Question

a perfume is sold at a gain of 5%. had it been sold for rs 49 more the gain would have been 12%. find the cost price of the perfume​

Answer 1

let,

the cp(cost price) = Rs. x

5℅ of x = x × 5/100 =x × 1/20 = x/20

Again,

12℅ of x = x × 12/100=x × 3/25 = 3x/25

Now,

x/20 + 49 = 3x/25

=>49=3x/25 - x/20

=>49=12x-5x/100

=>49=7x/100

=>4900=7x

=>7x=4900

=>x=4900/7

=>x=700

so the cp of the perfume is = Rs. x = Rs. 700.

hope it's useful ☺☺
