(A) 8
(B) 64
(C) 96
(D) 102
(E) 144
OA is C
If 80% of the packages weigh more than 25 pounds, then 20% weigh less. The problem states that there are 48 packages weighing less than 25 pounds.
Thus, 20% of X = 48, where X is the total number of packages
X = 240.
If 60% of the packages weigh less than 75 lbs, then that means 144 packages weigh less.
60% of 240 = 144
Question is how many weigh more than 25 lbs but less than 75 lbs.
Thus, 144 - 48 = 96 packages
The answer is C
