Question

A dealer sells a toy for 24ru. and gains as much percent as the cost price of toy.find cost price of toy?

Answer 1

Step-by-step explanation:

1. let cost price - 100
2. and profit 100% that is Rs.100
3. so selling price will be 100+100 = 200

so when selling price is 200 , cost price is 100

in the same way

when selling price is 24 then cost price will be

$24 \times 100 \div 200 = 12$
