What is the Average of New Set Number? If
The average of ten numbers is 7. If each number is multiplied by 12, then the average of the new set of numbers is:
- 7
- 19
- 82
- 84
Answer: (4) 84
Explanation:-
The average of ten number = 7
Then, the sum of ten number = 10 x 7 = 0
Each number is multiplied by 12,
Then, the sum of 10 numbers = 70 x 12
= 840
The average of 10 numbers = 840/10
= 84
Hence, the answer is (4) 84.
