AnswEr :

Let the Present Age of Son be n.

• P R E S E N S T ⠀A G E S :

◗ Son = n

◗ Father = 3(Son) = 3n

· · ──────────── · ·

• A F T E R ⠀3 ⠀Y E A R S :

◗ Son = Present + 3 = (n + 3)

◗ Father = Present + 3 = (3n + 3)

━━━━━━━━━━━━━━━━━━━━━━━━

• According to the Question Now :

↠ Father = Twice the Age of Son + 7 yrs

↠ (3n + 3) = 2(n + 3) + 7

↠ 3n + 3 = 2n + 6 + 7

↠ 3n + 3 = 2n + 13

↠ 3n – 2n = 13 – 3

↠ n = 10 ⠀⠀[ Son Present Age ]

∴ Present Age of Son will be 10 years.

Answer 2

Answer:

Son's Present Age is 10 years

Step-by-step explanation:

We Have :-

Father's Age = 3 * ( Son's Age )

After 3 years :-

Father' Age = Present Age + 3

Son's Age = Present Age + 3

To Find :-

Present age of Son

Solution :-

Let Son's present age be x

Father's present age = 3x

After 3 years :-

Father's age = 3x + 3

Son's age = x + 3

Acc to the question

( 3x + 3 ) = 2 ( x + 3 ) + 7

3x + 3 = 2x + 6 + 7

3x - 2x = 6 + 7 - 3

x = 10

Son's present age is 10 years
