Question Members of a school council have raised ₹ 70,500. They plan to setup a Maths Lab with some games and models worth ₹ 39,785, buy library books worth ₹ 9,545, and purchase sports equipment worth ₹ 19,548.
(a) Estimate whether the school council has raised enough money to make the purchases. Share your thoughts in the class.
(b) Check your estimate with calculations.
(a) Estimated amount required for Math lab with some games and models (₹ 39,785) = ₹ 40,000.
Estimated amount required for library books (19,545) = ₹ 10,000
Estimated amount required for sports equipment (₹ 19,548) = ₹ 20,000
Total estimated amount
= ₹ 40,000 + ₹ 10,000 + ₹ 20,000 = ₹ 70,000
Amount raised = ₹ 70,500.
So, school council has enough money.
(b) Now, calculating actual total cost:
₹ 39,785 + ₹ 9,545 + ₹ 19,548 = ₹ 68,878
Money raised by school council = ₹ 70,500.
Balance amount = ₹ 70,500 – ₹ 68,878 = ₹ 1,622.
Therefore, school council will be left with ₹ 1,622 after all the purchases.
