Answer 2

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%.
