SSC CHSL Average question with solution
AverageModerateSSC CHSL 2024
The average of 6 numbers is 52. If one number is removed, the average of the remaining numbers becomes 49. What is the removed number?
- (A)61
- (B)67
- (C)18
- (D)52
Correct answer: (B) 67
Sum of all 6 numbers = 6 × 52 = 312. Sum of the remaining 5 numbers = 5 × 49 = 245. The removed number is the difference: 312 − 245 = 67.
Shortcut: Removed number = old average + (n − 1) × (old average − new average) = 52 + 5 × (3).
