Then,present age of his father=3x
ATQ
After 5 yrs sum of their ages=70
After 5 yrs age of Rohan=x+5
And,Age of his father after 5 yrs=3x+5
So,x+5+3x+5=70
4x+10=70
4x=60
x=60/4=15
Hence,present age of Rohan=x=15
And,Present age of his father=3x=3×15=45

Answer 2

• The present age of Rohan is 15 years.
• The present age of Rohan's father is 45 years.

Step-by-step explanation:

• Let the present age of Rohan be x years

• Let the present age of Rohan's father be 3x

◑ After 5 years :-

• Rohan's age = (x + 5) years

• Rohan's father's age = (3x + 5) years

◑ Equation :-

= (x + 5) + (3x + 5) = 70

= x + 5 + 3x + 5 = 70

= 4x + 10 = 70

= 4x = 70 - 10

= 4x = 60

= x = 60/4

= x = 15

◑ Their present age :

• Rohan's age = x = 15 years

• Rohan's father's age = 3x = 15(3) = 45 years
