Question

After selling 12 balls a man suffer a loss equal to cost price of 6 balls. Find loss percent?

Answer 1

Let the S.P of one ball be $S$ and Cost price of one ball be $C$

Total Sale price = $12S$

Total Cost Price = $12C$

So,Loss = $12C-12S=6C$

Thus $\frac{S}{C}=\frac{1}{2}$

So Loss %=$50$%
