Question

A man gets a profit of 28% after allowing discount of 11(1/9)%. Find how much percent the cost price should be increased to make this Mark Price?

Answer 1

Let the cost price be $C$

And let the marked price be $M$

According to question $C\times \frac{128}{100}$ $=M\times \frac{8}{9}$

i.e $M=\frac{144}{100}C$

So he has to increase cost price by $44$%
