Question

1)Two cycles were bought at the same cost. One was sold at the profit of 15% and another was sold at a loss of 10% . If the difference in selling price is Rs.200 ,find the cost price of the cycles.

Answer 1

Let the cost of radios be x.
sp of radio-1
s.p=cp(100+p%/100)
=x(100+12/100)
=112x/100
sp of radio-2
x(100+17/100)
=117x/100

given, sp of radio-1 - sp of radio-2 =125
117x/100 - 112x/100 = 125
5x/100=125
5x=125 X 100
5x=12500
x=12500/5
x=RS.2500
cp of radios=2500
sp of radio-1=2500(100+12/100)
                  =2500 X 112/100
                  =RS.2800
sp of radio-2=2500(100+17/100)
                  =2500 X 117/100
                  =RS.2925
