Question 5

Commercial Arithmetic

Factory P produces 20,000 bags of cement per day while Q factory produces 15,000 bags per day. If P reduces production by 5% and Q increases production by 5%, determine the effective loss in the number of bags produced per day by the two factories.

A.250
B.750
C.1000
D.1250

Show the answer and explanation

Answer: A (250)

Explanation

P loses 5% of 20,000 = 1,000 bags and Q gains 5% of 15,000 = 750 bags. The overall loss is 1,000 − 750 = 250 bags.
