The average of seven numbers is 13.4. The average of two of them is 11.6, while the average of the other two is 14.5. What is the average of the remaining three numbers?

12.5

13.86

14.7

14.8

Sum of the remaining two numbers = (13.4 x 7) – [(11.6 x 2) + (14.5 x 2)] = 93.8 - (23.2 + 29) = 41.6. Required average = 41.6/3 = 13.86
