Vikas is planning his retirement , and planning to invest 5,000 per month in a Mutual fund for 20 yrs where he expects a return of 15% , then take out all the amount after 20 yrs and then put it in a FD for 15 yrs which gives him 9.5% return .
Here , we there are two parts
A. He makes monthly payment for 20 yrs (here we have to apply annuity)
B. then he takes the money out after 20 yrs and then put it in FD for 15 yrs (as this is one time payment , here we will apply compound interest)
A )
n = 240 and i = 1.25% (as the payment are monthly)
A = P * [{(1+i)^n - 1 }/i] * (1+i) (if payment are being made at the start)
His money after 20 years = [5,000 * (1 + .0125)^240 - 1) / .0125] * ( 1.0125) = 75,80,000 (75 lacs)

Now he invests this money into a FD for 15 yrs at 9.5% .
B) Final amount = 75,80,000 * (1.095)^15 = 2,95,00,000 (2.95 crores OR 29.5 millions)
