Question

A shopkeeper purchased a clock for 300 and sell it at a gain of 20% find the selling price of the clock

Answer 1

Let's compare :

If the clock was purchased for100 then it's sp was 120[20%gain] same way if the clock was purchased for 300 then sp was x(20%gain)

Now cross multiply

100 120

300 x

100x=120×300

100x=36000

x=36000/100

x=360

Therefore the sp of clock is Rs360
