To solve the problem, we need to determine how Lucy can use her available notes and coins (Rs 20, Rs 10, Rs 5, and Rs 2) to pay for each toy. Let's break it down step by step for each toy.
Toy 1: Car (Rs 40)
Lucy needs to pay
Rs 40. The possible combinations using her notes and coins are:
-
2 × Rs 20 = Rs 40
So, Lucy can give:
- 2 notes of Rs 20.
Toy 2: School Bus (Rs 25)
Lucy needs to pay
Rs 25. The possible combinations using her notes and coins are:
-
1 × Rs 20 + 1 × Rs 5 = Rs 25
So, Lucy can give:
- 1 note of Rs 20 and 1 coin of Rs 5.
Toy 3: Balloon (Rs 27)
Lucy needs to pay
Rs 27. The possible combinations using her notes and coins are:
-
1 × Rs 20 + 1 × Rs 5 + 1 × Rs 2 = Rs 27
So, Lucy can give:
- 1 note of Rs 20, 1 coin of Rs 5, and 1 coin of Rs 2.
Final Answer
Now, let's summarize the solution in the required format:
1.
Car (Rs 40):
\[
\text{Rs } 20 + \text{Rs } 20 + \text{Rs } 0 + \text{Rs } 0
\]
2.
School Bus (Rs 25):
\[
\text{Rs } 20 + \text{Rs } 0 + \text{Rs } 5 + \text{Rs } 0
\]
3.
Balloon (Rs 27):
\[
\text{Rs } 20 + \text{Rs } 0 + \text{Rs } 5 + \text{Rs } 2
\]
Boxed Final Answer:
\[
\boxed{
\begin{array}{l}
\text{Car (Rs 40): } \text{Rs } 20 + \text{Rs } 20 + \text{Rs } 0 + \text{Rs } 0 \\
\text{School Bus (Rs 25): } \text{Rs } 20 + \text{Rs } 0 + \text{Rs } 5 + \text{Rs } 0 \\
\text{Balloon (Rs 27): } \text{Rs } 20 + \text{Rs } 0 + \text{Rs } 5 + \text{Rs } 2
\end{array}
}
\]
