SSC CGL Average question with solution
AverageModerateSSC CGL 2024
The average of 5 numbers is 23. If one number is removed, the average of the remaining numbers becomes 24. What is the removed number?
- (A)23
- (B)19
- (C)14
- (D)24
Correct answer: (B) 19
Sum of all 5 numbers = 5 × 23 = 115. Sum of the remaining 4 numbers = 4 × 24 = 96. The removed number is the difference: 115 − 96 = 19.
Shortcut: Removed number = old average + (n − 1) × (old average − new average) = 23 + 4 × (-1).
