Meenu bought two fans for Rs 1200 each. She sold one at a loss of 5% and the other at a profit of 10%. Find the selling price of each. Also find out the total profit or loss.

Solution: For the first fan,
C.P. $=1200$ Rs
Loss $=5\%$
So, S.P. $=1200\ast \frac{95}{100}=1140$ Rs
For second fan,C.P. $=1200$ Rs
Profit $=10\%$
So, S.P. $=1200\ast \frac{110}{100}=1320$ Rs
Cost price of both fans $=1200+1200=2400$ Rs
Selling price of both fans $=1140+1320=2460$ Rs
So, Meenu${}^{\prime }$s total profit $=2460-2400=60$ Rs
