Let’s solve each problem step by step.
---
Problem 1:
It costs 15 rupees for one child to go swimming.
How much would it cost for 3 children?
→ We multiply the cost for one child by the number of children:
15 × 3 = 45
✔ So, it costs
45 rupees for 3 children.

Problem 2:
Baloo bought 3 chocolate bars at 13.25 rupees each.
How much did he spend altogether?
→ Multiply 13.25 by 3:
First, think of 13.25 as 13 + 0.25
13 × 3 = 39
0.25 × 3 = 0.75
Add them: 39 + 0.75 = 39.75
Or do it directly:
13.25
× 3
------
39.75
✔ So, Baloo spent
39.75 rupees.

Problem 3:
How much change will he get if he pays 50 rupees?
→ He spent 39.75 rupees (from Problem 2).
He paid with 50 rupees.
Change = Amount Paid – Amount Spent
= 50 – 39.75
Let’s subtract:
50.00
–39.75
-------
10.25
✔ So, he gets
10.25 rupees in change.

Problem 4:
A sandwich costs 8 rupees. How much will it cost in total to buy a sandwich for 5 kids?
→ Multiply 8 by 5:
8 × 5 = 40
✔ So, it costs
40 rupees for 5 sandwiches.

Final Answer:
1. 45 rupees
2. 39.75 rupees
3. 10.25 rupees
