It is under future value of annuity immediate
Given future value of annuity (F) = Rs. 10,00,000
Number of years = 5, r = 16%
∴ We have to find the value of annuity

⇒ 10,00,000 × 0.16 = A[(1.16)5 – 1]
1,60,000 = A[2.0990 – 1]
1.099 A = 1,60,000
∴ A = $$\frac{160000}{1.099}$$ = 1,45,586.90
Calculate (1.16)5
(5 log to 6 = AL (5 × 0.00644)
= AL)0.322) = 2.990
The company set aside Rs. 1,45,586.90 each year to get Rs. 10,00,000 at the end of 5 years.
