Let the CP be Rs. x
then,SP= Rs. x-x/5
According to the question,
x-x/5=45
4x/5=45
x=45×5÷4 =225/4=56.25
CP= Rs.56.25
loss= 56.25-45=Rs. 11.25
loss%=11.25/56.25×100=20%
then,SP= Rs. x-x/5
According to the question,
x-x/5=45
4x/5=45
x=45×5÷4 =225/4=56.25
CP= Rs.56.25
loss= 56.25-45=Rs. 11.25
loss%=11.25/56.25×100=20%
