Question

Pls solve this , 1. The selling price of 12 pencil boxes is equal to the cost price of 15 pencil boxes . Find the gain percent or loss per cent ?

Answer 1

Let the C.P of 1 pencil box be Rs.1

Therefore,

The C.P of 15 pencil box = Rs. 15

Given,

C.P of 15 pencil box = S.P of 12 pens.

So, S.P of 12 pencil box = Rs.15

Selling Price of 1 pencil box = Rs. 1.25

Gain= Rs. 0.25

Gain percent= Gain x 100/C.P %

  = 0.25 x 100/1 %

  =25/1 %

  = 25 %

Therefore, the gain percent is 25
