Question

Mr thapa bought 150 kg of oranges.18 kg were rptten and not fit for selling.if she sold the remaining quantity of oramges at the rate of 80per kg and gained 10% find the costpride of oranges

Answer 1

Step-by-step explanation:

total kg of oranges available for selling= 150-18

= 132 kg

s.p. of 1kg= 80 rs

so, s.p. of 132 kg= 132*80

= 10560 rs.

c.p. = s.p.* [100/(100+gain%)]

therefore,

c.p. = 10560*(100/110)

= 1056000/110

= 9600 rs.

c.p. per kg = 9600/150

= 64 rs.

Therefore, cost price of 150 kg is 9600 rs., 64 rs. per kg.

hope it helps :)
