Answer 2

Answer:

Rs. 2525750

Step-by-step explanation:

1st donation = Rs.125000

2nd donation = Rs.54000

3rd donation = Rs.54000 + 5250 = Rs.59250

4th donation = Rs.59250 + 5250 = Rs.64500

and so on

The AP will be from 2nd donation

Here, a = 54000, d = 5250, n = 22

Amount collected in 22 donations

= Sum of 22 terms

= 22/2[2 x 54000 + (22-1)×5250]

= 11 [108000 + 110250]

= 2400750

Amount to collect after 23 donations

= 2400750 + 125000

= Rs.2525750
