Answer 2

Question :-

The ratio of the present ages of Anjali and Ashu is 2 : 3. Five years from now, the ratio their ages will be 3 : 4. Find their present ages.

Solution :-

Given :-

• The ratio of the present ages of Anjali and Ashu is 2 : 3.
• Five years from now, the ratio their ages will be 3 : 4.

To Find :-

• Their Present age.

Step-by-Step-Explaination :-

Let Anjali's present age = 2x years

Ashu's present age = 3x years

Five years later, Anjali's age = (2x + 5) years

Ashu's age = (3x + 5) years

According to the question, we have

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \frac{(2x + 5)}{(3x + 5)} = \frac{3}{4}$

By cross multiplication, we have

4 (2x + 5) = 3 (3x + 5)

=> 8x + 20 = 9x + 15

=> 20 - 15 = 9x - 8x

=> 5 = x

Therefore, Anjali's present age = 2x years

= ( 2 × 5 ) years = 10 years

and Ashu's present age = 3x years

= ( 3 × 5) years = 15 years
