[ A ] 17
[ B ] 12

[ D ] 16

Answer : Option C

Explanation :

The average of 6 quantities is 10. Therefore, the sum of all 6 quantities is 60. The average of 4 of them is 8. Therefore the sum of 4 quantities = 32 Therefore, the sum of the remaining two quantities = (60 – 32) = 28 Hence the sum average of the 2 qunatities
= $28\over2$= 14
