Factory P produces 20,000 bags of cement per day while factory Q 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
correct option: a
P produces 20,000 bags
P reduces production by 5%
i.e. reduction = \(\frac{5}{100}\) x \(\frac{20000}{1}\)
= 1000
Q produces 15000 bags
Q increases production by 5%
i.e. increase = \(\frac{5}{100}\) x \(\frac{15000}{1}\)
= 750
Effective loss by the two = 1000 - 750
= 250 bags
P reduces production by 5%
i.e. reduction = \(\frac{5}{100}\) x \(\frac{20000}{1}\)
= 1000
Q produces 15000 bags
Q increases production by 5%
i.e. increase = \(\frac{5}{100}\) x \(\frac{15000}{1}\)
= 750
Effective loss by the two = 1000 - 750
= 250 bags
