Question

The selling price of 15 articles is equal to the cost price of 12 articles. Find the gain or loss as percent.

Answer 1

*.P. of 15 articles = C.P. of 12 articles

Let C.P. of 1 article = Re.1

C.P. of 12 article = Rs.12 and

C.P. of 15 articles = Rs.15

*.P. of 15 articles = Rs.12

[*.P. of 15 articles = C.P. of 12 articles]

Loss = Rs.15 – Rs.12 = Rs.3

Loss% = (3/15) x 100 = 20%
