Given : Sn = Rs.3750
n= 10
as given in equation
a, a-50, a-100 ...........
a= a
d= a-50-a= -50
Sn= n/2(2a +(n-1)d)
3750= 10/2(2a+9(-50))
3750=5 (2a-450)
750=2a - 450
a=600
put a= 600 to find value
Hence the prizes distributed are as follows.
Rs. 600,550,500,450,400,350,300,250,200,150.
Hope it helps you
