Question

A radio set was being sold at a profit of 25% The C.P. and S.P. increased by Rs. 100 each. If the profit in the new transaction was 20%, find the original CP

Answer 1

Cost price will be 400

Step-by-step explanation:

Let the cost price of radio set is x

Profit = 25 %

So profit = 0.25x

So selling price = cost price + profit = x+0.25x = 1.25x

Now the cost price and selling price both are increased by 100

So new cost price = x+100

And new selling price = 1.25x+100

So  new profit = 1.25x+100-(x+100) = 0.25x

According to question new profit is 20 %

$=\frac{(x+100)\times 20}{100}$

So $\frac{(x+100)\times 20}{100}=0.25x$

$1.25x=x+100$

x = 400
