SSC CHSL Average question with solution
AverageModerate
The average of 11 numbers is 28. If one number is removed, the average of the remaining numbers becomes 26. What is the removed number?
- (A)26
- (B)37
- (C)48
- (D)22
Correct answer: (C) 48
Sum of all 11 numbers = 11 × 28 = 308. Sum of the remaining 10 numbers = 10 × 26 = 260. The removed number is the difference: 308 − 260 = 48.
Shortcut: Removed number = old average + (n − 1) × (old average − new average) = 28 + 10 × (2).
