Sonu went to a shop. He wanted to buy a chiki and a toffee. One chiki costs Rs. 0.75 and a toffee costs Rs.0.50. If he buys one each of them how much he has to pay to the shop keeper. Sonu's mother gave him Rs.2. He gave it to shopkeeper and bought items of Rs.1.25. How much he will get in return? Suppose if his mother gave her Rs.5 then how much will the shopkeeper return?
Price of one Chiki = Rs. 0.75
Price of one Toffee = Rs. 0.50
Sonu buys one each of them, so he has to pay =1×0.75+1×0.50=Rs1.25
Sonu's mother gave him Rs. 2
Sonu paid Rs. 1.25 to the shopkeeper.
The money, Sonu will get in return =2.00−1.25=Rs. 0.75
If his mother gave him Rs. 5 and Sonu paid Rs. 1.25 to the shopkeeper.
The money, Sonu will get in return =5.00−1.25=Rs. 3.75
