Question

Rakesh purchased a radio set for Rs 300 and sold to kishan at a profit of 25% . Kishan sold it to Madan at a loss of 10%. For how much did Madan buy it

Answer 1

25 % =+ 1/4 , + 1 represent profit upon 4
4 unit = 300
1 unit = 300/4 = 75
5 unit = 75 × 5 = 375
again Madan buy at 10% loss
10 % =- -1/10 ,here -1 represent loss upon 10
10 unit = 375
1 unit = 375/10
9 unit = 37.5 × 9 = 337.5
