    Answer: (c) 20 years
    Explanation:-
    Let be the age of Kiran = X years and the age of Lila = Y years

    According to question,   (X-10) = 4(Y- 10)
    X – 10 = 4Y – 40
    X – 4Y = – 30                        ……………………..(1)

    Again,                                   (X +10) = 2(Y +10)
    X +10 = 2Y + 20
    X – 2Y = 10                           …………………………..(2)

    Solve equation (1) & (2)
    Y = 20 and X = 50

    Hence, the Lila’s present age is 20 Years.
