The average of four numbers is 44. The average of the first and second is 40, and that of the third and fourth is 48. What is the second number if the first is 36?

Show answer & explanation

Correct answer: A

Explanation

Given:

Average of four numbers = 44

Average of the first and second = 40

Average of the third and fourth = 48

First number = 36

Formula:

Average = (Sum of numbers) / (Number of numbers)

First + second = 40 × 2 = 80

36 + second = 80

Second = 80 − 36 = 44
