Average questions with solutions
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
Show answer and explanation
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).
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
Show answer and explanation
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).
The average of 8 numbers is 48. If one number is removed, the average of the remaining numbers becomes 46. What is the removed number?
- (A)54
- (B)16
- (C)62
- (D)48
Show answer and explanation
Correct answer: (C) 62
Sum of all 8 numbers = 8 × 48 = 384. Sum of the remaining 7 numbers = 7 × 46 = 322. The removed number is the difference: 384 − 322 = 62.
Shortcut: Removed number = old average + (n − 1) × (old average − new average) = 48 + 7 × (2).
The average of 10 numbers is 47. If one number is removed, the average of the remaining numbers becomes 50. What is the removed number?
- (A)10
- (B)50
- (C)20
- (D)47
Show answer and explanation
Correct answer: (C) 20
Sum of all 10 numbers = 10 × 47 = 470. Sum of the remaining 9 numbers = 9 × 50 = 450. The removed number is the difference: 470 − 450 = 20.
Shortcut: Removed number = old average + (n − 1) × (old average − new average) = 47 + 9 × (-3).
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
Show answer and explanation
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).
