SSC CHSL Average question with solution
AverageModerate
The average of 8 numbers is 34. If one number is removed, the average of the remaining numbers becomes 33. What is the removed number?
- (A)49
- (B)41
- (C)8
- (D)33
Correct answer: (B) 41
Sum of all 8 numbers = 8 × 34 = 272. Sum of the remaining 7 numbers = 7 × 33 = 231. The removed number is the difference: 272 − 231 = 41.
Shortcut: Removed number = old average + (n − 1) × (old average − new average) = 34 + 7 × (1).
