1. If the average of two numbers is M and the larger number is L, what is the other number?
- A. M - L
- B. M - L
- C. M - L
- D. M - L
Answer: Option C
Explanation:
average of two numbers is M
one number is L
let second number be X
average = L + X/2
= > M = L + X/2
= > 2M = L + X
= > 2M - L = X
therefore,second number is 2M - L
