If I invest 2000000 compounded monthly at 1.5% rate per month.what will amount after 16 years or 192 months

the formula for compunding interest is:

FV = PV(1+i)^n

where PV = present value, or 2000000 for this problem.
I = interst rate in percent per time reriod, or 0.015.
n = number of times, or 192.

Plug this into your calculator and see what you get.
