Answer:
=======

Let the present age of Raj and Rajitha be 4x and 9x.

Now,

$9x = 2(9x - 12) - 3$

$9x = 18x - 24 - 3$

$9x = 18x - 27$

$27 = 18x - 9x$

$27 = 9x$

$\frac{27}{9} = x$

$x = 3$

Raj's present age

$= 4x = 12 \: years$

After 5 years Raj's age will be,

$12 + 5 = 17 \: years$

Therefore,

Correct option A) 17 years

Answer 2

Answer:

OptionA

Step-by-step explanation:

Ratio of present age of Raj's and Rajitha's is 4:9.

Let the age of Raj and Rajitha be 4x and 9x.

According to the given condition,

9x = 2(9x - 12) - 3

9x = 18x - 24 - 3

9x = 18x - 27

9x = 27

x = 3.

So, Raj's age after 5 years =  12 + 5 = 17 years.

Hope it helps you.
