Question

. Suman bought 100 bulbs at Rs.25 each. 12 bulbs out of it are defective and thrown away. The remaining are sold for Rs.30 each. Find her profit or loss%.

Answer 1

Step-by-step 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
