12. You have 30 rupees with you. Find out how much money will be left after buying the following items: One ball, one doll and one toy giraffe. Total cost of Rs. 21.50. Money left
Rs. 8.50.
Ans. Cost of 1 ball = Rs. 7
Cost of 1 doll = Rs. 8
Cost of 1 toy giraffe = Rs. 6.50
So, Total cost = Rs. 7 + Rs. 8 + Rs. 6.50 = Rs. 21.50
Money left = Total Money – Money Spent = Rs. 30 – Rs. 12.50 = Rs. 8.50.

13. Two bananas, one pack of biscuits and two glasses of lemon juice. Total cost Rs. 13.50.

Cost of 1 pack of biscuits = RS. 4.50
Cost of 2 glasses of lemon juice = Rs. 3 x 2 = Rs. 6
So, Total cost = Rs. 3 + Rs. 4.50 + Rs. 6 = Rs. 13.50
Money left = Total money – Money spent
= Rs. 30 – Rs. 13.50 = Rs. 16.50.
