Question 1

Which of the following numbers is divisible by 3?

Accepted Answer

85,019,457

Answer

A number is divisible by 3 if the sum of its digits is divisible by 3. For 85,019,457, the sum of its digits is 8+5+0+1+9+4+5+7 = 39. Since 39 is divisible by 3 (39 ÷ 3 = 13), the original number 85,019,457 is also divisible by 3.

Question 2

What should come next in the following sequence? 64a, 55b, 46c, 37d, 28e, ?

Accepted Answer

5 years 4 months

Answer

The pattern is descending increments of 9 followed by the first letter, second letter, third letter, and so on.

Question 3

If y + 3y + 5y = −18, then what is the value of y?

Accepted Answer

−2

Answer

First, combine the like terms on the left side of the equation: y + 3y + 5y simplifies to 9y. The equation then becomes 9y = -18. To solve for y, divide both sides of the equation by 9. This gives y = -18 / 9, which results in y = -2.

Question 4

The sum of 7 numbers is greater than 140 and less than 210. Which of the following could be the average (arithmetic mean) of the numbers?

Accepted Answer

26

Answer

The average (arithmetic mean) of a set of numbers is their sum divided by the count of numbers. Given that the sum of 7 numbers is greater than 140 and less than 210, the average must be between 140/7 and 210/7. This means the average must be greater than 20 and less than 30. Of the given options, only 26 falls within this range.

Question 5

If b does not equal zero, and ab = b/4, what is the value of a?

Accepted Answer

1/4

Answer

To find the value of 'a', we need to isolate 'a' in the given equation `ab = b/4`. Since 'b' does not equal zero, we can divide both sides of the equation by 'b'. This simplifies the equation to `a = (b/4) / b`, which further reduces to `a = 1/4`.
