Question

THE PRESENT AGE OF SAHIL MOTHER IS THREE TIMES THE PRESENT AGE OF SAHIL. AFTER 5 YEARS THEIR AGES WILL ADD TO 66 YEARS. FIND THEIR PRESENT AGES

Answer 1

let the present age of Sahil be x,sahil's mother age be 3x.5years later sahil's age is x+5,sahil's mother's age is 3x+5.sum if their ages after 5years is 4x+10.

4x+10=66
4x=66-10
x=56÷4
x=14.
sahil's present age is 14& sahil's mothers age is 3×14=42 years.
after 5 years
sahil's age is 14+5=19
sahil's mother age is 42+5=47
19+42=66years

Answer 2

Let the present age of Sahil = y years

Let the present age of Sahil's mother= x years.

Given that present age of Sahil's mother is three times the present age of Sahil

$x = 3y$

After five years Sahil's age will be

$y + 5$

After five years Sahil's mother age will be

$x + 5 \\ = 3y + 5$

Now, it is given that after 5 years the sum of their ages will be 66.

$y + 5 + 3y + 5 = 66 \\ 4y + 10 = 66 \\ 4y = 66 - 10 \\ 4y = 56 \\ y = 56 \div 4 \\ y = 14$

Sahil's age

$y = 14 \: years$

Sahil's mother age is

$x = 3y \\ = 3 \times 14 \\ = 42 \: years$

Therefore, present ages of Sahil and Sahil's mother are 14 years and 42 years
