Question

Raman's current age is 7 time the age of his daughter, Dia. Five years from now, Dia's age will be
twice her present age. Find Raman's age when his daughter was born .​

Answer 1

Answer:

Required Answer:-

Let the age of Raman's daughter be x and age of Raman be y. Then according to question..

⇒ x = 7y

⇒ Or, x - 7y = 0 -------(1)

Now adding 5 years to each of them. This is to equate the relation between their age after five years. Dia's age will be twice her present age.

Then,

⇒ x + 5 = 2x

⇒ x = 5

Raman's present age will be 7 × 5 = 35. When Dia was born, she was 0 years old. Then, Raman must be 35 - 5 = 30 years (Ans) old then.

Answer 2

Answer :

• Raman's age when his daughter was born is 30 years

Given :

• Raman's current age is 7 time the age of his daughter Dia
• After five years Dia's age will be twice of her present age

To find :

• Raman's age when his daughter was born

Solution :

• Let the Raman's age be x years
• Let the Dia's age be y years

Given that ,

Raman's current age is 7 times the age of his daughter Dia so,

》x = 7y

Now After 5 years ,

• Dia's age is (y + 5)

According To Question, Given that, Dia's age will be twice her present age so ,

》y + 5 = 2y

》2y - y = 5

》y = 5

• Present age of Dia's is 5 years

• Present age of Raman's is x = 7y = 7 × 5 = 35years

Now we have to find the Raman's age when his daughter was born ,

》(35 - 5) years

》30 years

Hence , Raman's age when his daughter was born is 30 years
