SSC CGL Average question with solution
AverageModerateSSC CGL 2024
The average of 5 numbers is 26. If one number is removed, the average of the remaining numbers becomes 29. What is the removed number?
- (A)14
- (B)19
- (C)29
- (D)26
Correct answer: (A) 14
Sum of all 5 numbers = 5 × 26 = 130. Sum of the remaining 4 numbers = 4 × 29 = 116. The removed number is the difference: 130 − 116 = 14.
Shortcut: Removed number = old average + (n − 1) × (old average − new average) = 26 + 4 × (-3).
