Best Ans:

Percent of people’s who is given by Tk.120 = 100 - 30 - 45 = 25%

Number of peoples who is given by Tk. 120 = 18,000/120 = 150

Now, 25% of people’s = 150

So, Total number of people’s = (150*100/25) = 600

Total contribution = (600*0.3*2,400) + (600*0.45*1,200) + 18,000 = 774,000 Tk.

Ans: 774,000 Tk.
