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%
