Question

A farmer bought hundred hens for rupees 4000 and sold 20 of them at a gain of 5%.At what gain percent must he sell the remaining so as to gain 20% on the whole transaction.​

Answer 1

Answer:

Now,

Selling price of 80 articles =4800−840=Rs.3960

Cost price of 80 articles =40×80=Rs.3200

Gain =3960−3200=Rs.760

Therefore,

Gain % on 80 articles =

3200

760

×100=23.75%

Hence Ravish must sell the remaining articles at 23.75% gain.
