    According to question ,
    Mother’s age - Sum of her two daughters’ age = 6.
    The average age of two daughters = 22
    Total age of two daughters = 22 × 2 = 44 years
    ∴ The age of their mother = Total age of two daughters + 6 years

    Suppose that the present age of Geetha is P years
    10 years after , age of Hema = 40 years
    Present age of Hema = 40 – 10 = 30 years
    According to question
    10 years ago , 2( present age of Geetha – 10 years ) = present age of Hema – 10
    ⇒ 2( P – 10 ) = 30 – 10
    ⇒ 2P – 20 = 20
    ⇒ 2P = 20 + 20 = 40

    Correct Option: B

    Suppose that the present age of Geetha is P years
    10 years after , age of Hema = 40 years
    Present age of Hema = 40 – 10 = 30 years
    According to question
    10 years ago , 2( present age of Geetha – 10 years ) = present age of Hema – 10
    ⇒ 2( P – 10 ) = 30 – 10
    ⇒ 2P – 20 = 20
    ⇒ 2P = 20 + 20 = 40

    ∴ P =
    40
    = 20 years
    2

    Hence ,the present age of Geetha is 20 years .
