SSC CGL Average question with solution
AverageModerateSSC CGL 2024
The average of 7 numbers is 26. If one number is removed, the average of the remaining numbers becomes 25. What is the removed number?
- (A)26
- (B)32
- (C)7
- (D)25
Correct answer: (B) 32
Sum of all 7 numbers = 7 × 26 = 182. Sum of the remaining 6 numbers = 6 × 25 = 150. The removed number is the difference: 182 − 150 = 32.
Shortcut: Removed number = old average + (n − 1) × (old average − new average) = 26 + 6 × (1).
