Answer 1

Answer:

The present age of his daughter is 8 years  .

Step-by-step explanation:

Given as :

The statement are as

(i) The age of man is 4 times the age of his daughter

Let The Age of man = M years

let The Age of daughter = D years

According to statement

The Age of man = 4 × The Age of daughter

i,e M = 4 × D

Or, M = 4 D               .......1

Again

(ii ) After 16 years, The age of man is twice the age of his daughter

So, After 16 years , Age of man = (16 + M) years

And The age of daughter = (D + 16) years

According to statement

After 16 years, The age of man = 2 × the age of his daughter

i.e M + 16 = 2 × (D + 16)

Or, M + 16 = 2 D + 32

Or, M - 2 D = 32 - 16

Or, M - 2 D = 16           .........2

Solving eq 1 and eq 2

∵ M = 4 D

So, 4 D - 2 D = 16

Or, 2 D = 16

∴     D = $\dfrac{16}{2}$

i,e D = 8 years

So, the present age of daughter = D = 8 years

Hence, The present age of his daughter is 8 years  . Answer
