Question

a shopkeeper purchased 200 bulbs for Rs 10 each. however 5 bulbs were fused and had to be thrown away. The remaining were sold at Rs 12 each. Find gain or loss percent.​

Answer 1

Answer:

17%

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

Profit

×100=

2000

340

×100=17

∴ Profit is Rs.340 or 17%.

Answer 2

Answer:

total cp is 200 *10 which is 2000

and price of fused one is 50 so 2000-50

which is 1050.

then 105 remaining bulbs

105*12 which is 1260

and then 1260-1050 =210

gain percent =sp-cp /cp*100

=210/1050*100

=20%
