Question
Mangoes are bought at 20 for Rs. 60. If they are sold at 33 percent profit. Find:
(i) selling price of each mango.
(ii) S.P. of 8 mangoes.
Solution
C.P. of 20 mangoes = Rs. 60
Gain = `33 1/3 % = 100/3 %`
∴ S.P. of 20 mangoes `= ("C.P." xx (100 + "gain %"))/100`
`= (60(100 + 100/3))/100`
= Rs. `(60 xx 400)/(100 xx 3)` = Rs. 80
(i) S.P. of 1 mango = Rs. `80/20` = Rs. 4
(ii) S.P. of 8 mangoes = Rs. 4 × 8 = Rs. 32
