Question

23. A shopkeeper purchased 400 glasses for 20 each. During transportation 10 glasses were broken. The remaining were sold at 724 each. Find the gain 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 =

Answer 2

cp for 400 Glasses - rs 400 cp for 1 Glass-rs 20

10 Glasses were broken during

Transportation = 400-10-390

Now,

cp of 390 glasses = 390*20-7800

Now he sell 390 glasses for RS24 for each

Now sp of 390 glasses = 390*24 =9560 rs

Gain = sp-cp

= 9560-7800

=1760 rs
