Question

A shop keeper purchased 200 bulbs for 10 each. However 5 bulbs were fused and put them into scrap. The remaining were sold at R 12 each. Find the gain or loss percent.






​

Answer 1

Explanation:

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 =

C.P

Profit

×100=

2000
