Q. 74.7( 34 Votes )
A shop keeper purchased 200 bulbs for Rs. 10 each. However 5 bulbs were fused and put them into scrap. The remaining were sold at Rs. 12 each. Find the gain or loss percent.
Answer :
Number of bulbs purchased at Rs. 10 = 200
Purchase price = 200 × 10 = Rs. 2000
If 5 bulbs were defective, remaining bulbs = 195
Sale price = 12
Sale price of 195 bulbs = 195×12 = Rs. 2340
Profit = sale price – purchase price
= 2340 – 2000
= Rs. 340
= 17%
∴ The gain percent is 17%
