Question

Mohan deposits rs 500 in the first month ,rs 550 in the second month, rs 600 in the third month and so on find the total deposits at the end of 5 years

Answer 1

Answer:

Here, we are given first term i.e. 500 , then we have common difference of Rs. 50.

We can calculate number of months he deposited his money. According to the question, he deposited money for 5 years and in each month, so total months = 5 × 12 = 60 months -

So, now we have -

a = 500

d = 50

n = 60

=60/2 [2*500+(60 -1)50]

=30[2*500+(59)50]

=30[2*500+2950]

=30[1000+2950]

=30[3950]

=118500

Total money he deposited at the end of 5 years = Rs. 118500
