Answer:

Step-by-step explanation:

Let the PRESENT agr of Sana be 'a'. So the present age of Ratna is:

5 year more than age of Sana

= 5 year more than a

= a + 5

After 4 years;

= > age of Sana = pres. age + 4 = a + 4

= > age of Ratna = pres. age + 4 = a + 5 + 4 = a + 9.

Difference in their ages:

= > a + 9 - (a + 4)

= > a + 9 - a - 4

= > 9 - 4

= > 5

Moreover, DIFFERECE in ages will always be same, no matter after how MANY YEARS you count.
