Question

a bookseller sells 100 pens and gains rupees one on each Pens by selling 10 dozen pencils he losses 10 paise per pencil what is his gain or loss

Answer 1

Answer:

Gain = Rs. 88

Explanation:

Profit per pen = Rs. 1

Total profit on 100 pens = 100 × Profit per pen = 100 × 1 = Rs. 100

10 dozen = 10 × 12 = 120 (1 dozen = 12)

Loss per pencil = Rs. 0.1 (Rs. 1 = 100 paisa)

Total loss on 120 pencil = 120 × loss per pencil = 120 × 0.1 = Rs. 12

Final profit or loss = Total profit on 100 pens - Total loss on 120 pencil

= 100 - 12

= Rs. 88

As final result is positve. Therefore, it is profit.

So, bookseller's gain is Rs. 88.
