Question

The cost of your article is first decreased by 25percent and then further decreased by 40percent cahnge in cost of the article.

Answer 1

Let Cost price = 100

25 % decrease

25% of 100 = 25

So CP becomes 100 -25 = 75

now again 40 % is decreased.

now CP was 75

40% of 75 = 30

New CP 75 - 30 = 45

CP WAS reduced from 100 to 45

so total reduction is 55 out of 100.

so answer is 55 %
