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
