The college has raised 75% of the total amount needed by receiving an average donation of ₹600 from 60% of the people who will be solicited.
Let the total number of people to be solicited be P, and the total amount required be A.
Formula used:
The amount raised so far = 75% of A = 0.75A.
The number of people already solicited = 60% of P = 0.60P.
The average donation from these people = ₹600.
Therefore, the total amount raised so far is:
Total amount raised so far = 0.60P × 600 = 0.75A.
Calculation:
⇒ 0.60P × 600 = 0.75A
⇒ 360P = 0.75A
⇒ A = (360P ÷ 0.75) = 480P
Now, the amount needed from the remaining 40% of people = A - 0.75A = 0.25A = 0.25 × 480P = 120P.
The remaining 40% of people = 0.40P.
The average donation required from the remaining people = (Amount to be raised) ÷ (Remaining people) = 120P ÷ 0.40P = ₹300.
∴ The average donation from the remaining people must be ₹300.
