The average of 25 numbers is 150. One more number is added and the new average became 160. What is that new number?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 410.
The average of 25 numbers is 150.
Sum of 25 numbers = 25 × 150 = 3750
One new number is added, and the average becomes 160.
Sum of 26 numbers = 26 × 160 = 4160
New number = 4160 - 3750 = 410
The new number added is 410.
