Question 56
A reduction of 20% in the price of rice enables a customer to purchase 4kg more for Rs.120. Then find original price of rice per kg
Solution
$$4$$ kg$$\rightarrow$$ Rs.$$120$$
then $$1$$kg $$\rightarrow$$ Rs.$$\Large\frac{120}{4}$$ $$=$$ Rs.$$30$$
Reduced price: $$30$$ $$\times$$ $$\Large\frac{20}{100}$$ $$=$$ Rs.$$6$$/kg
Original price: $$6$$ $$\times$$ $$\Large\frac{100}{(100-20)}$$ $$=$$ $$6$$ $$\times$$ $$\Large\frac{100}{80}$$ $$=$$ Rs.$$7.50$$/kg
