Question

by selling 60kg of rice, a shopkeeper make a profit equivalent to the cost price of 8kg of rice. what percent profit does the shopkeeper make?​

Answer 1

Answer:

13.33%

Step-by-step explanation:

so by selling 60kg of rice he gets the money equivalent to (60+8)=the price of 68 kg rice.

let's assume that the cost price of 1 kg rice to him is 1 rupee.

so, he makes 8 rupees of profit out of 60 rupees.

so, the profit is (8/60)×100 =40/3 = 13.33%

(mark this as brainliest if I helped you out )

Answer 2

Step-by-step explanation:

let CP of 1 kg rice= x rs

then CP of 8 kg rice=8x rs

let SP of 1kg rice=y rs

then SP of 60 kg rice=60y rs

CP of 60kg rice= 60x rs

profit on selling 60 kg rice = 60y-60x=60(y-x)

according to the question , profit=CP of 8kg rice

then ,60(y-x)=8x

60y=68x

y=68x/60=17x/15

then profit %= (y-x)100/x

now put value of y in it

(17x/15 -x)100/x=13.33%
