Answer 2

Given :-

Ratio of the ages of Sona and Sonali = 5 : 3

Ratio of their ages five years later = 10 : 7

To Find :-

The present age of Sona.

The present age of Sonali.

Analysis :-

Consider the common ratio as a variable.

Make an equation accordingly.

Once you get the value of the variable, substitute it in the ratio of the present age given in the question.

Solution :-

Consider the common ratio as a variable. Then their present ages would be 5x and 3x years respectively.

Ages after 5 years,

Sona = 5x + 5 years

Sonali = 3x + 5 years

Making an equation,

5x + 5/3x + 5 = 10/7

7(5x + 5) = 10(3x + 5)

35x + 35 = 30x + 50

Taking like terms,

35x - 30x = 50 - 35

5x = 15

By transposing,

x = 15/5

x = 3

Finding their ages,

Present age of Sona = 5x

= 5 × 3 = 15 years

Present age of Sonali = 3x

= 3 × 3 = 9 years

Therefore, the present age of Sona and Sonali are 15 years and 9 years respectively.
