An example:

Question:

A shopkeeper 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:

No. of bulbs =200, Cost of each bulb =10

Total C.P=200×10=2000

5 of them were discarded so only (200−5)=195 were sold, at a rate of 12 per each bulb.

Total S.P=195×12=2340

Profit or loss =S.P–C.P=2340–2000=+340 (Profit)

Percent profit = $Profit\\C.P$  ×100= $340\\2000$  ×100=17

∴  Profit is Rs.340 or 17%.
