Question

The cost price of 36kg rice is Rs 1040. On selling 36kg rice, a shopkeeper earns a profit equal to the selling price of 10kg rice. Find the selling price of 5kg rice.

Answer 1

Answer:

184.567902 rs

Step-by-step explanation:

rupees of 36 kg rice = 1040

rupees of 1 kg rice = 1040 / 36

= 28.889 rs.

rupees of 10 kg rice = 28.89 * 10

= 288.89 rs

total = price of rice + profit earn equal to 10 kg

total = 1040 + 288.89

total = 1328.89 rs.

then the selling price of 5 kg rice is :-

= ( 1328.89 / 36 ) * 5

= 184.567902 rs.

Answer 2

Answer:

200

Step-by-step explanation:

let x be the profit on 36 kg rice

from given condition

((1040+x)/36)*10=x

Solve for x.

10400/36+10x/36=x

x-10x/36=10400/36

36x-10x=10400

26x=10400

x=400

selling price of one kg

((1040+400)36)=40

selling price of 5 kg

40*5=200
