Answer 2

Concept:

Here the concept of percentage is used here.

So, to solve the problem of percentage we just need to divide the given number by hundred i.e. x%= x/100.

Given:

We know that shopkeeper always weighs 20% less than the correct weight.

Find:

We need to find the effective percentage of profit in this transaction.

Solutions:

Let we assume that correct weight be 100 kg and the cost price (C.P) be Rs. 100.

Then profit on the correct weight is 20% , therefore selling price (S.P.) = Rs. 120

As we know that he weighs 20% less than the original weight i.e.= 100*0.8= 80 kg

Now  one day he weight 20% more than 80 = 80*1.2= 96 kg

That means he sold 96 kg for Rs 120 and C.P of 96 kg is Rs 96.

Now, profit % = (120-96)/96 * 100 = 25%

Hence, the final answer is 25%.
