Answer:-
Let
Daughter's age be x
Reena's age =3x(5 years after)
Daughter's age be x-5
Reena's age be 3x-5
Sum of age at this time=(x - 5)+(3x - 5)=62
⇒4x+(-10)=62
⇒4x=62+10[bringing (- 10) to this side]
⇒x=72/4=18
⇒(3x - 5)=3×18 - 5
⇒54 - 5 =49↦Reena's age
⇒18 - 5 = 13↦daughter's age

Step-by-step explanation:
Solution :
Let,
- Present age of Reena's daughter = x
- Present age of Reena = 3x
In 5 years,
- Age of Reena's daughter = x + 5
- Age of Reena = 3x + 5
★ According to the Question :
The sum of their ages will be 62 years
⇒ (x + 5) + (3x + 5) = 62
⇒ 4x + 10 = 62
⇒ 4x = 62 - 10
⇒ 4x = 52
⇒ x = 52/4
⇒ x = 13
Present age of Reena's daughter = 13 year
Therefore, the daughter’s present age is 13 year
