Question

Ratio of present age of Rakhi and Sita 5:7 in 8 years Rakhi will be of 28 years. What was the age
of Sita 5 Years earlier?

Answer 1

Explanation:

Ranjana's present age

= 15x years

Rakhi's present age = 17x years

After 6 years,

$\frac{15x + 6}{17x + 6} = \frac{9}{10}$

=> 153x - 150x = 60 - 54

=> 3x = 6 => x = 2

Therefore, Raniana's age after 6years

= 15x + 6

$(15 \times 2 + 6) \: years \: = \: 36years$

Answer 2

Answer:

Ranjana's present age

= 15x years

Rakhi's present age = 17x years

After 6 years,

\frac{15x + 6}{17x + 6} = \frac{9}{10}

17x+6

15x+6

=

10

9

=> 153x - 150x = 60 - 54

=> 3x = 6 => x = 2

Therefore, Raniana's age after 6years

= 15x + 6

(15 \times 2 + 6) \: years \: = \: 36years(15×2+6)years=36years
