(d) 60,000​

Answer 1

Answer:

Step-by-step explanation:

if we have

1 month = x

2 month= x+100

3 month = x +100+100

.

.

.

we get the formula as = x +100(n-1) where x is the first month sum and n is the number of months

1st month = 2000

number of months = 10

total sum = 2000 +100(10-1)

=2000+900

=2900, Hope this helps

Answer 2

It is an A.P so we need to find n=10,a=2000 d=100. Sn=n/2(2a+(n-1)d. Sn=10/2(2*2000+(10-1)100
=5(4000+900)
=5(4900)
=24500
