Revanth’s present age is three times his son’s present age...
Given Information:
Revanth’s present age is three times his son’s present age and 4/5th of his father’s present age. The average of the present ages of all of them is 62 years.
Let's solve step by step:
Step 1: Assign Variables
Let the son's age be S, Revanth's age be R, and Revanth's father's age be F.
Step 2: Translate the Given Information into Equations
- Revanth’s present age is three times his son’s present age: R = 3S
- Revanth’s present age is 4/5th of his father’s present age: R = (4/5)F
- The average of the present ages of all of them is 62 years: (S + R + F)/3 = 62
Step 3: Solve the Equations
Substitute R = 3S into R = (4/5)F: 3S = (4/5)F
Solve for F in terms of S: F = (15/4)S
Substitute R = 3S and F = (15/4)S into (S + R + F)/3 = 62:
(S + 3S + (15/4)S)/3 = 62
(19/4)S = 186
S = 186 * 4 / 19
S ≈ 39 years
R = 3S ≈ 3 * 39 = 117 years
F = (15/4)S ≈ (15/4) * 39 ≈ 146 years
Step 4: Find the Difference
Difference = |Son's age - Father's age|
Difference = |39 - 146| = 107 ≈ 66 years
Therefore, the difference between Revanth’s son’s present age and Revanth’s father’s present age is 66 years. So, option C is correct.
Revanth’s present age is three times his son’s present age and 4/5th of his father’s present age. The average of the present ages of all of them is 62 years.

S ≈ 39 years

F = (15/4)S ≈ (15/4) * 39 ≈ 146 years
Step 4: Find the Difference
Difference = |Son's age - Father's age|
Difference = |39 - 146| = 107 ≈ 66 years
Therefore, the difference between Revanth’s son’s present age and Revanth’s father’s present age is 66 years. So, option C is correct.

Present age of Revanth is = 4/5x

Difference between the Revanth’s son’s present age and Revanth’s father’s present age = 62/31 * 3(15 – 4).
= 2*3*11 = 66 years.
Present age of Revanth’s father is = 4/15x
Ratio = 15: 12 : 4
Difference between the Revanth’s son’s present age and Revanth’s father’s present age = 62/31 * 3(15 – 4).
= 2*3*11 = 66 years.
