Poonam has Rs.150 for her class outing. The park entry fee is Rs.40 and the museum entry fee is Rs.60. She also wants to buy an ice‑cream for Rs.20 and keep Rs.10 for a small souvenir. Can she afford all these activities? Show your calculation.
Answer
Yes, she can afford everything.
The correct answer is Yes, she can afford everything. — She will have Rs.150 - Rs.130 = Rs.20 left after the outing.
Step-by-step solution
- List all the expenses: park Rs.40, museum Rs.60, ice‑cream Rs.20, souvenir Rs.10.
- Add the expenses step by step:
- First add the park and museum fees: Rs.40 + Rs.60 = Rs.100.
- Add the ice‑cream cost: Rs.100 + Rs.20 = Rs.120.
- Finally add the souvenir amount: Rs.120 + Rs.10 = Rs.130.
- Compare the total expense Rs.130 with the money she has Rs.150.
- Since Rs.130 ≤ Rs.150, she has enough money.
- She will have Rs.150 - Rs.130 = Rs.20 left after the outing.
Common mistake: Adding the costs incorrectly, e.g., adding Rs.40 + Rs.60 + Rs.20 = Rs.110 and forgetting the souvenir amount.
Concept tested: Simple addition and budgeting for a day out.
