Among a group of students, 20 like mathematics, 15 like science, and 10 like both mathematics and science. If every student in the group likes at least one subject, what is the minimum number of students in the group?

The minimum number of students in the group is the sum of students who like mathematics and those who like science, minus the number of students who like both subjects. So, 20+15−10 = 25 Since every student likes at least one subject, the minimum number of students is 25 + 10 = 35.

In a group of employees, 60% are women, 40% are managers, and 20% are both women and managers. If every manager is a woman, what percentage of the women are managers?

Since every manager is a woman, the percentage of women who are managers is the same as the percentage of managers, which is 40%. Therefore, the percentage of women who are managers is 60%×40%=33.33%.

A cylindrical container has a diameter of 14 inches and a height of 6 inches. Since one gallon equals 231 cubic inches, the capacity of the tank is approximately

The capacity of the tank is given by πr^2h = π(7^2)(6) = 923.628 cubic inches Since 1 gallon is equal to 231 cubic inches, the capacity of the tank in gallons is 923.628 / 231 = 3.998 gallons Which is approximately 4 gallons. So the answer is B.

Kajol took loan from a bank at the rate of 12% p.a. simple interest. After 3 years, she had to pay PKR 5400 interest only for the period. The principal amount borrowed by her was:

We can use the following formula to calculate the simple interest: Simple Interest = (Principal * Rate * Time) / 100 Where: Principal is the amount of money borrowed. Rate is the interest rate per year. Time is the number of years the loan is borrowed for. We know that the simple interest is PKR 5400, the rate is 12% p.a., and the time is 3 years. We need to calculate the principal. Substituting the known values into the formula, we get: 5400 = (Principal * 12 * 3) / 100 Multiplying both sides of the equation by 100, we get: 540000 = Principal * 12 * 3 Dividing both sides of the equation by 12 * 3, we get: Principal = 540000 / (12 * 3) Principal = PKR 15000 Therefore, the principal amount borrowed by Kajol was PKR 15000.

If an equilateral triangle and a square have the same perimeter, what is the ratio of the length of the sides of the equilateral triangle to the lengths of the sides of the square?

Let the side length of the equilateral triangle be x and the side length of the square be y. Since they have the same perimeter, we know that: 3x=4y Dividing both sides by 3, we get: x= 4/3(y) Therefore, the ratio of the side lengths of the equilateral triangle to the side lengths of the square is 4:3.

If half the range of increasing series {11, A, 23, B, C, 68, 73} is equal to its median, what is the median of the series?

Let's analyze the given series: {11, A, 23, B, C, 68, 73}. The median of a series is the middle value when the values are arranged in ascending order. In this case, the series is already in increasing order: {11, A, 23, B, C, 68, 73} Now, if half the range is equal to the median, we need to find the range and divide it by 2. Range = Largest value - Smallest value In this series, the largest value is 73, and the smallest value is 11. Range = 73 - 11 = 62 Half the range = 62 / 2 = 31 Now, we need to find the element in the series that is 31 units away from the smallest value (11). Counting 31 units from 11, we get: 11 + 31 = 42 So, the element with the value 42 is the median of the series. Therefore, the median of the series {11, A, 23, B, C, 68, 73} is 42.
