A. 15

B. $$15\frac{1}{5}$$

C. 14

D. $$14\frac{1}{5}$$

Answer: Option B

Solution(By Examveda Team)

Average of 12 numbers = 15
Total of 12 numbers = 15 × 12 = 180
Average of first two number = 14
Total of first two number = 14 × 2 = 28
Total of remaining ten numbers = 180 - 28 = 152
Required average of remaining ten number
$$\eqalign{ & = \frac{{152}}{{10}} \cr & = \frac{{76}}{5} \cr & = 15\frac{1}{5} \cr} $$
