The average of 12 numbers is 15 and the average of the first two numbers is 14. What is the average of the remaining numbers?

15.2

14.2

✅ Correct Option: 2

Sum of 12 numbers = 12 x 15 = 180.

Sum of first 2 numbers = 2 x 14 = 28.

Sum of remaining 10 numbers = 180 - 28 = 152.

Average of remaining 10 numbers = 152/10 = 15.2.
