    Let Ajay's age 10 years back be x years.
    Then Sachin's age 10 years back = 2x years
    ∴ 2x + 20 = 40

    Correct Option: A

    Let Ajay's age 10 years back be x years.
    Then Sachin's age 10 years back = 2x years
    ∴ 2x + 20 = 40
    ⇒ x = 10
    ∴ Present age of Ajay = x + 10 = 20 years

    ∵ 3x + 5x = 80
    ⇒ x = 10
    Ratio of their ages after 10 years = (3x + 10) : (5x + 10)

    Correct Option: A

    ∵ 3x + 5x = 80
    ⇒ x = 10
    Ratio of their ages after 10 years = (3x + 10) : (5x + 10) = 40 : 60 = 2 : 3
