Question

A sells goods to B at a profit of 20percent and B sells it C at a profit of 25percent if C pays rs225 for it,what was the cost price for A?

​

Answer 1

Answer:

Let Suppose cp for A is 100rs

Sp =Cp+profit

100+100×20/100

100+20= 120 rs

Now 120 rs is cp for B

Cp+ profit margin

120+25%

120+120×25/100

120+30=150rs

Sp will 150rs

If 150 pay the cp is 100

If paid 1 the cp is 100÷150

Therefore 225×100÷150=150 rs
