GIVEN: The arithmetic mean of a, b, c, and d is 14
In other words: (a + b + c + d)/4 = 14
Multiply both sides by 4 to get: a + b + c + d = 56

The mean of a + 3b + 2d and a - b + 2c - 48 = [(a + 3b + 2d) + (a - b + 2c - 48)]/2
= [2a + 2b + 2c + 2d - 48]/2
= a + b + c + d - 24
= 56 - 24
= 32

We get:
QUANTITY A: 32
QUANTITY B: 32

Answer: C
