Question

Megha bought 10 note-books for Rs.40 and sold them at Rs.4.75 per note-book. Find, her gain percent.

Answer 1

C.P. of 10 note-books = Rs. 40

S.P. of 10 note-books @Rs. 4.75 per note-book

= 4.75 × 10 = Rs. 47.50

Gain = S.P. − C.P.

= Rs. 47.50 − Rs. 40 = Rs. 7.50

Gain%`="Gain"/"C.P."xx100`

`=7.50/40xx100=750/40%`

`=75/4%`

`=18 3/4%`
