Question 1011890
the formula for compound interest is:
A= P(1+r/n)^nt
where: 
A is the final amount
P is the initial investment (rs 1000)
r is the interest rate (10%/100= 0.10)
n is the number of periods (compounded half yearly will be 2 periods)
and finally, the exponent:
nt is the number of periods times the number of years
Since I don't understand "interest of two years" and I don't want to give you a bad answer, please plug in the numbers in the above formula and work your calculator to get your answers.
