Question

If the purchase is 4/5 times of the sale, what will be the percentage of profit or loss?​

Answer 1

Answer:

Profit%=25%

Step-by-step explanation:

Let the Selling price be 100

Then, according to the question

Cost price = 4/5of 100

=4/5×100=80

SP is greater than CP so there will be a profit

Profit% =Profit×100/CP

=(100-80)×100/80=25%answer

We can use other method

Let SP be X

Then, CP= 4/5of X =4x/5

Profit%=(x-4x/5)×100/4x/5

=25% answer
