Question

a shopkeeper purchased 200 bulbs for rs 10 each however 5 bulbs were fused and put them into scrap the remaining were sold at rs 12 each find the gain or loss percent

Answer 1

Hey sup!

As per the question,

Cost price of bulb= 200×10=2000Rs.

Selling price of bulb= 195×12=2340Rs.

Profit= 2340-2000=340Rs.

Profit%=340/2000 × 100.
=34/2.
=17%.

Hope it helps.

Answer 2

Total Cost price of bulbs = 200 × 10
C.P = ₹ 2000

Selling price of the total bulbs when 5 are fused = 195 × 12

S.P = ₹2340

So, When S.P > CP it is gain .

Gain = S.P - C.P

= 2340 - 2000

= ₹ 340

So, he gained ₹340

$gain\% = \frac{gain}{c.p} \times 100$

$= \frac{340}{2000} \times 100$

= 17 %

So, he gained 17%
