1. A school has raised 75% of the amount it needs for a new building by receiving an average donation of Tk 60 from the people already solicited. The people already solicited represent 60% of the people the college will ask for donations If the college is to raise exactly the amount needed for the new building , how much must the remaining people donate per person?
- A. Tk 25
- B. Tk 25
- C. Tk 25
- D. Tk 25
Answer: Option B
Explanation:
Let Total people = 100
60% people of total people = 60
They donate amount = 60×60 = 3600
Remaining people = 100 - 60 = 40
And remaining amount = ( 3600×100) 75 - 3600 = 4800 - 3600 = 1200
They donate per person = 1200/40 = 30Tk.
