Question

By selling a radio rupees 500 Manish lost 10
percent for how much should he sell the radios so as to gain 8%

Answer 1

500 = 90/100
(50000/90 ) 108= (90/90) 108
60000 = 108
60000/100

he should sell = 600

Answer 2

Find the percentage of the selling price:

100 - 10 = 90%

Find the cost Price:

90% = Rs 500

1% = 500 ÷ 90 = Rs 50/9

100% = 50/9 x 100 = Rs 5000/9

Find the price if he wants to sell it with a 8% gain:

8% of 5000/9 = 0.8 x 5000/9 = Rs 400/9

Selling Price = 5000/9 + 400/9 = RS 600

Answer: He should sell the radio at Rs 600
