उत्तर
Let the age of Rakesh be x years.
Then, the age of Sania = (x + 5) years
According to the question, the sum of the ages of Sania and Rakesh is 27 years.
∴ x + (x + 5) = 27
⇒ 2x + 5 = 27
⇒ 2x = 27 − 5
⇒ 2x = 22
⇒ x = `22/2`
⇒ x = 11
Sania’s age = x + 5
= 11 + 5
= 16 years
∴ The ages of Rakesh and Sania are 11 years and 16 years, respectively.
