Q & A

How many combinations are there for a 4-digit password where each digit ranges from 0 to 9?

There are 10,000 possible combinations. This is calculated as 10^4 (10 choices for each of the 4 digits).

What is the total time Alice will take to try all 10,000 password combinations, if each try takes 3 seconds?

Alice will take a total of 30,000 seconds (10,000 combinations × 3 seconds per try). This is equivalent to 500 minutes.

If Ben's father's age is 5 times Ben's age 10 years ago, what is the current age of Ben's father?

The current age of Ben's father is 50 years. This is calculated by setting up an equation based on the age ratio 10 years ago.

What is the total volume of a mixture after removing 5 liters of a 70% orange juice solution and adding pure orange juice, when the final mixture is 73% orange juice?

The total volume of the mixture is 50 liters. This is calculated by solving the equation based on the percentage of orange juice before and after the addition.

In a train problem with 15 stations, how many different tickets are required for smooth ticketing operations?

A total of 210 tickets are needed. Each of the 15 stations needs tickets for 14 other stations (15 × 14).

What is the probability of picking a prime-numbered ticket from a set of tickets numbered 1 to 30?

The probability is 1/3. There are 10 prime numbers between 1 and 30, so 10/30 simplifies to 1/3.

Which of the following is the correct form of the sentence 'The Lions a strong team compete against the Cowboys that play tough defense'?

The correct sentence is: 'The Lions, a strong team, compete against the Cowboys who play tough defense.'

In the sentence 'Bob is so Dash that it is nearly impossible to offer him constructive criticism without him taking it personally,' what is the correct word to fill in the blank?

The correct word is 'obdurate,' meaning stubborn.

What is the best alternative for the phrase 'a large number of courses' in the sentence 'Universities today offer a large number of courses and it has improved the quality of education'?

The best alternative is: 'Universities today offer so many courses that they have improved the quality of education.'

In a simple interest problem, if the principal of Rs 6,500 earns the same interest in 1 year as Rs 4,500 earns in 2 years, what are the rates of interest?

The rates of interest are 40/11% and 70/11%, respectively, based on the conditions given in the problem.
