# Mrs. Menon Plans to Save for Her Daughter'S Marriage. - Mathematics and Statistics

Sum

Mrs. Menon plans to save for her daughter's marriage. She wants to accumulate a sum of ₹ 4,00,000 at the end of 4 years. How much should she invest at the end of each year from now, if she can get interest compounded at 10% p.a. ?

[Given (1.1)4 = 1.4641]

#### Solution

Given A = ₹ 4,00,000

Period (n) = 4 years

Rate of interest (r) = 10%

Annuity immediate (C) = ?

i = "r"/100 = 0/100 = 0.1

A = "C"/"i" [(1 + "i")^"n" - 1]

400000 xx 0.1 = "C" [(1.1)^4 - 1]

40000 = C  [1.4641 - 1]

40000 = C [0.4641]

C = 40000/0.4641

C = 86188.32

C = 86188

∴ Mrs. Menon should invest ₹ 86188 at the end of each year.
