Question

Ratna is 5 years younger than Sana. After 4 years , what will be the age difference between the two please say answer

Answer 1

Answer:

5

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.

Answer 2

Sana's present age = x years.

Ratna's present age = x-5 years

Sana's age after 4 years = x+4 years.

Ratna's age after 4 years = x-5+4 = x-1 years.

Difference in their ages after four years:-

↣x + 4 - (x - 1)

↣x + 4 - x + 1

↣5

∴ Difference in their ages after four years = 5

【 The difference of their ages will always be equal to 5. It doesn't matter the number of years we count. 】
