Avg of a and b = 7
Therefore a + b = 7(2) = 14;
Avg of b and c = 11
Therefore b + c = 11(2) = 22;
Avg of a and c = 10
Therefore a + c = 10(2) = 20;
Adding (2) and (3):
= a + b + 2c = 42
= 14 + 2c = 42...(Since, a + b = 14)
= 2c = 28
= c = 14;
Avg of a, b and c:
= (a + b + c) / 3
= (14 + 14) / 3
= 28 / 3
= 9.333...
9.3333... > 9.3
Hence, Quantity A is greater
Therefore a + b = 7(2) = 14;
Avg of b and c = 11
