Question

A man has Rs. 20,000 in his account in a bank. He withdraws Rs. 3000 per month for the first two months and deposits double of this amount on the third month. What will be the balance in his account after 3 months?

Answer 1

A man debited 3000 in two consecutive months from 20,000.
Therefore, he had 20,000 - 2×3000 = 14,000

Now he also credits double of what he debited in two months
Therefore amount he credits will be 2×(2×3000) = 12,000.

Total amount in bank after 3rd month
= 14,000 + 12,000 = 26,000 Rs

Answer 2

Given:

Total amount = 20,000

Amount withdrawn per month for first 2 months = 3000

To Find:

balance after 3 months = ?

Solution:

we have,

Initial balance  = 20,000

now, 3000 is withdrawn per month for 2 months

balance = 20,000 - (3000 * 2)

balance = 20,000 - 6000

balance = 14,000

now, after 2 months 3rd month double is deposited.

balance = 14,000 + 6000 * 2

balance = 14,000 + 12,000

balance = 26,000

So, the balance in his account after 3 months = Rs 26,000.
