Answer 2

Step-by-step explanation:

Mrs. Limbu bought of oranges (c.p)=180kg

if oranges were rotten and not fit for selling = 15kg

she sold the remaining quantity of oranges = 180-15

=165 kg

she sold the remaining quantity of oranges(s. p) Rs. 78 par kg.

Now,

She sold the remaining quantity of oranges (s. p)

= 165×78

=Rs.12,870

gained/profit =10%

Now,

s. p = cp +profit%of c. p

or, 12870 = c. p + 10/100 ×c.p

or, 12870 =( 100c.p + 10c.p) /100

or, 12870×100 = 110c.p

or, 1287000/110= c. p

so, 11,700 = c. p

so c. p = 11700

the rate of cost price of oranges par kg = 11700/80

= Rs. 65

the rate of cost price of oranges par kg is Rs 65
