Question

if selling price = 75 and profit = 10 then the cost price is​

Answer 1

Answer:

If the cost price(x) is numerically equal to the profit percentage ,then the formula to be used is : x+x(square)/100=SP

It can be noticed that when x is substituted by 50,then L.H.S=R.H.S

That is, 50+2500/100=75

So the answer is 50.
