Q & A

What is the approximate benefit expense of the organization as a percentage of total expenses?

The benefit expense of the organization is approximately 27% of the total expenses.

How much is the total expense of the organization if the benefit expense is $216,000?

If the benefit expense is $216,000, and it represents 27% of the total expenses, the total expense can be calculated by dividing $216,000 by 27% (or 0.27), which equals $800,000.

What is the method to calculate the missing number in the circle with numbers 33 and 31?

The missing number is calculated by adding the numbers 33 and 31, then dividing the sum by 4. In this case, (33 + 31) / 4 = 16.

What word can be formed using all the letters t, f, a, l, c, u, p, m, and the definition of the word?

The word that can be formed is 'impactful', which means having a major impact or effect.

How many triangles are there in the given shape according to the video?

Transcripts

here's an amazing question with unusual

twist which tests your knowledge of the

pie chart

you're presented with stall spending for

the organization and you need to

calculate approximate benefits expense

in addition to benefits expense UC

payroll expense research and development

expense

as well as client entertainment

in your final selection is within one of

four possible choices choice a 170

000. 216

000 Choice C 296

000 and choose the 360 thousand dollars

take a close look maybe pause this video

to see if you can do a mental math and

come up with the solution radio not I am

moving forward to share with you my

version of the solution and obviously if

you have a better way to solve it please

make sure to share in comments first

step to solve it is to look at the chart

and identify the benefit segment

benefits represent 27 percent of all

expenses

to calculate the amount for benefits we

need to divide 800 000 which is total

expense by 100 and multiply by 27

because benefits represent 27 which

would be equal 8 000 multiplied by 27

which would be equal 216

000. so the correct Choice here is

Choice B two hundred and sixteen

thousand dollars

here is a puzzling question which has a

very surprising solution

you're presented with three circles each

circle is broken into three equal parts

the first Circle has numbers 8 19 and

13.

the second Circle has numbers 11 15 and

29. and then the third circle has

numbers 33 31 and then one number is

missing you need to calculate the

missing number out of four different

choices choice a 16. choose B17 Choice C

18 and then Choice d 20.

did you calculate the right answer

as I mentioned the solution to this

problem is really interesting so let's

move forward to get to the correct

solution together

if you're probably tired hearing this

and I'm tired repeating it but you need

to always look for patterns to solve

these types of problems

and the pattern here is that section 3

of the circle is calculated as sections

one plus two divided by four

so to calculate the missing number you

need to add 33 plus 31 and then divide

the sum by 4 and you will get to the

result which would be 16.

hopefully you enjoyed this tricky

question and now know how to answer

similar problems on the test

foreign

this question truly tests your knowledge

of English dictionary you need to form

the word using all the letters only once

in their nine letters that you can see

on the screen the letters are t f a l c

u p m I give yourself a little bit of

time it's a very complex nine letter

word

consider pausing the video to get to the

correct answer and ready or not I'm

going to move forward to get you to the

correct solution

as you might have guessed the correct

word is impactful

and the definition of impactful is

having a major impact or effect

sample usage of the word might be during

her presentation she made impactful

statements I get a lot of questions on

how to solve these types of challenges

the best way I found is when looking at

the letters try to draw lines connecting

the letters and see if you can come up

with the word in this case letters next

to each other in the real world are next

to each other also in this test question

so if we connect imp

a c t f u l you get to the correct

solution do you have a better way to

solve it please make sure to share in

comments so we can all learn

when I saw this question I couldn't

believe the answer you need to determine

how many triangles are presented in a

given shape

you see one triangle highlighted in red

but you have four different choices

choices a which is a triangles Choice B

10 triangles Choice C 12 triangles or

Choice D 14 triangles how many do you

see

give yourself a little bit of time to

see if you can come up with the solution

as I told you I was really amazed but

the correct Choice here is Choice D 14

triangles let me show them all to you

here they all are one

two

three four

five

six

seven

eight

nine

10 11.

12 13 and 14. did you see them all isn't

it amazing how many triangles can fit

into the simple shape I learned

something hopefully you did too and now

know how to answer similar problems on

the test

and now I think is an excellent time for

you to try your skills to see if you can

solve the challenge you need to

determine approximate percentage of

Tesla Model S Sales in 2023 you're

presented with the chart that shows

sales by model between period of 2021

and 2024 and you have four different

choices choice a 20 choose B 27 percent

Choice C 33 and then Choice D 40 give

yourself a little bit of time do the

mental math maybe pause this video to

see if you can get to the correct

solution once you're ready please make

sure to post your answer and comments so

I can give you my feedback thanks for

participating and good luck

I love this question because it really

makes you think in order to get to the

correct solution you need to determine

which shape comes next in the sequence

and you presented with the series of

five shapes squares one two three and

five have other smaller shapes inside

and you need to determine shape four you

have four different choices to choose

from choices a

B

C

and D

give yourself a little bit of time look

closely to see if you can get to the

correct answer

are you ready let's move forward and get

to the correct solution together

you're probably tired hearing it but my

advice as usual always look for patterns

and in this case the pattern is location

of the smaller shapes inside the square

you might have noticed that smaller

shapes inside the circles are always

Diamond filled with black

and oval with the black outline this

pattern is persistent for shapes 1 2 3

and 5.

we can safely assume that the square 4

will have similar shapes inside which

automatically exclude choices B and C

only live in possible choices as a and d

to solve this puzzle and get to the

correct solution we need to detect the

second pattern

and second pattern is that oval is

always next to the diamond either to the

right of the diamond or on top of the

diamond

based on this information the correct

Choice here is Choice D hopefully you'll

nail this question and now know how to

answer similar problems on the test but

in case you need more problems with

here is the frequently used question to

test how logical are you you need to

determine if conclusion is correct based

on a statement let's look at the

statement all soccer players are sports

persons and all sports persons are fit

conclusion

some soccer players are not fit and you

need to determine if this particular

conclusion is correct you have four

different choices to determine if

conclusion is accurate Choice a it's

reasonably correct choose B it is

correct Choice C it's incorrect and

choice D cannot be determined based on

the information available do you think

you know the answer give yourself a

little bit of time maybe pause this

video and take another look at the

statements and add the question itself

ready or not I'm going to move forward

and reveal the solution

as you might be well aware in logical

World there is a Formula if a equals b

and b equals c then you can reasonably

conclude that a equals c as well we can

look at our original statements as a b

and c for example the statement all

soccer players are sports persons could

be an equivalent of a equal B and then

all sports persons are fit could be b

equals c based on these two statements

we can reasonably say that a equals c

which would mean that all soccer players

are fit our question though asks us if

some soccer players are not fit do you

think it is correct based on the

information provided it is not correct

so the correct Choice here is Choice C

incorrect because the correct answer

based on the information we have is all

soccer players are fit do you have a

better way to solve this question please

make sure to share in comments and if

you're trying to get ready for the test

and need additional questions to

practice please make sure to check out

here's an interesting challenge where

you need to determine the relationship

between family members Amin is bhaskar's

sister

Catherine is bhaskar's Mother

then is Catherine's father and Alan is

Dan's mother you need to determine how

Amin is related to them

and you have four different choices

choice a grandfather Choice B

grandmother Choice C daughter and choice

D granddaughter

give yourself a little bit of time to

see if you can navigate in this puzzle

and get to the correct solution ready or

not I am going to move forward reveal

the answer to you and explain how I got

to the solution and as usual if you have

a better way to solve it please make

sure to share and comments

the easiest way to determine the

multi-generational relationship in the

family is to build a diagram let's do it

one step at a time

I mean is bhaskar's sister

Catherine is bhaskar's Mother

Dan is Catherine's father and Ellen is

Dan's mother now let's look at the

conclusions we can draw from this

diagram

a Catherine's children

since then is Catherine's father Amin

and Bhaskar are Dan's grandkids

which means that Amin is Dan's

granddaughter

so the correct Choice here is Choice D

granddaughter

hopefully you've nailed this question

and now know how to diagram and solve

similar problems on the test

here is one of my favorite questions

where you need to do mental math

calculations

you're presented with the group of four

numbers

in this group has an average of 24. the

first three numbers are 16 22 and 34.

you need to calculate the value of the

missing number which is represented as

the question mark and you have four

different choices choice a 24 choose b26

chose c18 and choose D21

can you do the math did you find the

answer

let's move forward so we can get to the

correct solution together

obviously to solve it you can plug in

one of the four Solutions instead of the

missing number calculate the average to

see which one is correct but we're going

to take the different route in the first

step we're going to calculate the sum of

three existing numbers so 16 plus 24

plus 34 equals 72.

in the next step we need to determine

what would be the sum of four numbers

for which average would be 24. to do

this we need to multiply 24 by 4 and the

end result of this would be 96.

and in the last step we need to subtract

the sum of three numbers from the total

where the average will be 24 to

calculate the force Number 96 minus 72

equals 24. let's verify this 16 plus 24

plus 34 plus missing number 24 divided

by 4 equals 96 divided by 4 equals 24.

hopefully nailed this question and now

know how to answer similar problems on

the test

and now here's the question for you to

try your skills you need to determine

how many triangles are shown on the

screen you have four different choices

Choice a eight Choice B 10 Choice C 12

and chose D14 feel free to pause this

video to calculate the right answer and

make sure to post your solution in

comments so I can give you my feedback

thanks for participating and good luck

here is an interesting question were you

presented with the set of numbers and

you need to determine which number is

not a prime number

you have four different choices choice a

31.

Choice B 61. Choice C 71 and choice d

91.

give yourself a little bit of time maybe

recall the definition of prime numbers

and see if you can come up with the

solution

did you solve it let's move forward and

get to the correct solution together

to solve this challenge let's start with

the definition of prime number

prime numbers cannot be divided by any

number other than 1 and number itself

without leaving a remainder

some examples of prime numbers would be

2 3 5 7 11 and you can continue the

chain

the opposite of prime numbers are

composite numbers and examples of those

would be 4 could be divided by two six

could be divided by two and three eight

which could be divided by two and four

nine ten and you can continue the

sequence

as you might have figured out out of the

numbers presented 91 can be divisible by

7. so 91 is not a prime number which

means that the correct solution is

Choice D 91. hopefully you've nailed

this question and now know how to answer

similar problems on the test

[Music]

here is a very interesting problem but

you might frequently get on the test you

need to determine the next item in my

sequence you're presented with the

sequence of large squares each large

Square contains nine small squares

inside and small squares are of the

different color you need to determine

next item in the sequence and you have

four different choices choices a b c and

d do you see the answer give yourself 10

to 15 seconds maybe longer maybe 20 to

30 seconds to see if you can come up

with the solution did you figure it out

let's go ahead move forward to get to

the correct solution together

as always my advice to you look for

patterns and determining the pattern is

key to solving this particular problem

which you need to know to answer this

particular question is that blue shape

moves within the row of the larger shape

in each row blue shape moves from left

to right one step at a time and once

blue shape reaches the end of the row on

the right it reappears on the left so

the correct answer here is Choice D

hopefully you've nailed this question

and now know how to answer similar
