Question

Babita bought 160 kg of mangoes at Rs 48 per kg. She sold 70% of the mangoes at Rs 70 per kg and the remaining mangoes at Rs 40 per kg. Find Babita’s gain or loss per cent on the whole dealing.

Answer 1

Given that, Babita bought 160 kg of mangoes at Rs. 48 per kg.

And sold 70% of mangoes at Rs. 70 per kg.

And the remaining mangoes at Rs. 40 per kg.

⇒ Total amount she paid (cost pice) = 48 × 160

= Rs. 7680

And Cost of 70% mangoes she sold = `160 xx 70/100 xx 70`

= Rs. 7840

⇒ The remaining % of mangoes = (100 – 70)% = 30%

⇒ Cost of remaining mangoes = `160 xx 30/100 xx 40`

= Rs. 1920

∴ The total amount she got by selling (selling price) = 7840 + 1920

= Rs. 9760

Now, ∵ Selling price (S.P) > Cost price (C.P)  ⇒ Gain

And Gain = S.P – C.P

= 9760 – 7680

= Rs. 2080

⇒ Gain % = `"Gain"/"C.P." xx 100`

⇒ Gain % = `2080/7680 xx 100`

⇒ Gain % = 27.08%
