Answer: your mom must deposit ₹752.68 each month if you want to retire  ₹700.

Step-by-step explanation:

You want ₹700 per month.

The interest rate is equal to 7%, this means that the amount your mam puts in the bank, will be reduced by a 7%.

So each month your mom will put X in the bank, we must have that X minus the 7% of X is equal to ₹700, this can be written as:

X - X*0.07 = 700

X*0.93 = 700

X = 700/0.93 = 752.69

So your mom must deposit ₹752.68 each month if you want to retire  ₹700.
