Question

The price of an article is reduced by 25% and it's daily sale increased by 30%. Find the net % effect on daily sale.

Answer 1

100 * 75/100 * 130/100        Here, reduce 25 -> 100-25=75, increase 30 -> 100+30
= 3/4 * 130
= 390/4
= 97.5
then, 100 - 97.5 = 2.5% loss
(I don't sure for this is correct or not)
