Question

Rajiv bought 20 glasses for rupees 60 each. she sold 7 of them at rupees 65 each. five glass broke. rest were sold at rupees 70 each. find the gain or loss per cent

Answer 1

c. p. of 20 glasses = 20*60 =1200
S. p. of 7 glasses = 7*65= 455
5 glasses broke so, = 60*-5= -300
remaining glasses = 20- (7+5) = 20 - 12 =8
so, S. p. of 8 glasses = 8*70= 560
so, total S p. = 455 +560 - 300 =715
loss = c. p. - S p.
= 1200-715= 485
loss percent = loss /c. p. *100
= 485 / 1200 *100
=40.41
40.41 percent loss

Answer 2

20 glasses for rupees 60 each

1 glass 60, 20 glasses= 20x60

cost price of 20 glasses =1200

7 glasses were sold at rupees 65 each

1 glass 65, 7 glasses =7x65

selling price of 7 glasses =455

5 glasses broke. it means there is no selling price(0 rupees) for it.

rest(8 glasses) glasses for rupees 70 each

(7 glasses+5 glasses=12 glasses)(20 glasses - 12 glasses=8 glasses)

1 glass 70 ,8 glasses =70x8

selling price of rest 8 glasses = 560

total cp =1200

total sp =455+0+560=1015

therefore there is a loss as selling price is less than cost price.

cp-sp=l

1200-1015=185

there is a loss of 185 rupees.

l%=l/cp x 100

l%=185/1200 x 100

zeroes get cancelled.

l%=185/12

l%=15.4(divide by 12)

there is 15.4 % loss
