Question

a shopkeeper buys 16 books at rs 250 per book. He sells 4 books at rs 200 per book and the remaining 12 books at rs 275 per book. Find his gain or loss percent

Answer 1

total cost =16×250=4000
cost of 4 books
4×200=800
cost of 12 books
12×275=3300
so total 16 books selling cost=800+3300=4100
so gain = 4100-4000=100
profit %=(100/4000)×100=2.5%

Answer 2

The shopkeeper had a gain of 2.5%.

Given:

Number of books bought = 16

Cost of buying each book = Rs. 250

4 books sold at Rs. 200 each

12 books sold at Rs. 275 each

To Find:

gain or loss percent

Solution:

Total cost price = 16 × 250

= 4000

Now, the selling price of 4 books = 4 × 200

= 800

The selling price of the remaining 12 books = 12 × 275

= 3300

⇒ Total selling price = 3300 + 800 = 4100

Profit = 4100 - 4000

= 100

Profit % = 100/4000 × 100

= 2.5

Thus, the shopkeeper had a gain of 2.5%.
