Question

simran bought pet food worth rs 56000.she then sold 1/3rd of it incurring a loss of 40%.what profit shw must earn on rest of the supplies to nullifies this loss​

Answer 1

Answer:

The price of pet food is useless here.

Let ‘s do the problem in another way.

Suppose she bought x kgs of pet food with price of 1 Rs. per kg.

The total buying cost was = (x. 1) = x Rs.

She sold x/3 kg of food at 40% loss.

So, the selling price of x/3 kg of food was = (x/3.1.60/100) = x/5 Rs.

The remaining food was of (x-x/3) = 2x/3 Rs.

She had to sell the remaining food in = (x-x/5) = 4x/5 Rs. for nullify the loss occurred.

So, she had to sell the remaining at= (4x/5–2x/3) = 2x/15 Rs. profit.

So, her profit % on the remaining part was = (2x/15.3/2x.100) = 100/5 = 20% (answer)

Answer 2

Given:

Simran bought pet food worth Rs. 56000. She then sold 1/3rd of it incurring a loss of 40%.

To Find:

What profit she must earn on rest of the supplies to nullifies this loss​

Solution:

Suppose Simran bought x kgs of pet food with price of 1 Rs. per kg.

The total buying cost was = (x. 1) =  Rs. x

She sold x/3 kg of food at 40% loss.

So, the selling price of x/3 kg of food was = ($\frac{x}{3} * 0.60$) =  Rs. x/5

The remaining food quantity = (x-x/3) = 2x/3

She had to sell the remaining food in = (x-x/5) = 4x/5 Rs. to nullify the loss occurred.

So, she had to sell the remaining at = (4x/5–2x/3) =  Rs.2x/15 profit.

So, her profit % on the remaining part was = (2x/15.3/2x.100) = 100/5 = 20%

Hence, Simran must earn 20% profit on rest of the supplies to nullify this loss​.
