Question

Que to the ratio of present ages of Rehana and have mother is 2:7
After 2 years, the seatio of
ages
?
their
will be
1:3 What is
Rehana's present age​

Answer 1

Let, the present age of Rehana and her mother be 2x and 7x respectively

Now, after 2 years their ages will be (2x+2) and (7x+2)

ATQ :

$\frac{(2x + 2)}{(7x + 2)} = \frac{1}{3} \\ \\ = > 6x + 6 = 7x + 2 \\ \\ = > 7x - 6x = 6 - 2 \\ \\ = > x = 4$

Now, present age of Rehana = 2x = 2×4 = 8 years.

and present age of her mother = 7x = 7×4 = 28 Years
