  1. Sachin was twice as old as Ajay 10 years back. How old is Ajay today if Sachin will be 40 years old 10 years later?

    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
