Deepti received Rs500 as pocket money. She bought a new dress using 40% of her pocket money. She bought crackers worth Rs100 and also a gift for her parents with the remaining amount. What was the cost of the gift she bought for her parents?

Answer

To solve the problem step by step, we can follow these calculations:

1. **Calculate the amount spent on the dress:**
Deepti received Rs 500 as pocket money. She spent 40% of her pocket money on a dress.
\[ \text{Amount spent on dress} = 40\% \text{ of } 500 = \frac{40}{100} \times 500 = 200 \text{ Rs} \]

2. **Calculate the amount spent on crackers:**
Deepti bought crackers worth Rs 100.
\[ \text{Amount spent on crackers} = 100 \text{ Rs} \]

3. **Calculate the total amount spent so far:**
Now, we add the amount spent on the dress and the crackers.
\[ \text{Total spent} = \text{Amount spent on dress} + \text{Amount spent on crackers} = 200 + 100 = 300 \text{ Rs} \]

4. **Calculate the remaining amount:**
To find out how much money is left for the gift, we subtract the total amount spent from the total pocket money.
\[ \text{Remaining amount} = \text{Total pocket money} - \text{Total spent} = 500 - 300 = 200 \text{ Rs} \]

5. **Conclusion:**
The remaining amount is the cost of the gift she bought for her parents.
\[ \text{Cost of the gift} = 200 \text{ Rs} \]

Thus, the cost of the gift Deepti bought for her parents is **Rs 200**.
