Question

A man has 100 rupees in his hand. He went to buy a bulb. So, he bought a bulb for 10 rupees.

Answer 1

Cost Price of 200 bulbs=Rs 10

Cost Price of 1 bulb=Rs(200×10)=Rs 2000

Number of bulbs fused =5

Number of bulbs remaining=(200-5)=195

Selling Price of 1 bulb=12

Selling Price of 195 bulbs=Rs(195×12)=Rs 2340

Since S.P.>C.P. ,so GAIN

Gain=(S.P.-C.P.)

       =Rs(2340-2000)=Rs 340
