## Karnataka 1st PUC Basic Maths Question Bank Chapter 9 Annuities

Question 1.

A company needs Rs. 10,00,000 at the end of 5 years from now. It would like to set aside an equal amount each year out of its profits. If the present marker rate of interest is 16%, how much should be annual amount to be invested?

Answer:

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 = A^{L} (5 × 0.00644)

= A^{L})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.
