    A 68 yrs Correct Answer Incorrect Answer
    B 55 yrs Correct Answer Incorrect Answer
    C 48 yrs Correct Answer Incorrect Answer
    D 30 yrs Correct Answer Incorrect Answer

    Solution

    ATQ,

    Sum of present ages of Neha and her uncle = 40 × 2 = 80 years

    Let the present age of Neha = x years

    Then, present age of her uncle = (80 - x) years

    According to the question,

    (x + 5) × 4 = (80 - x)

    ⇒ 4x + 20 = 80 - x

    ⇒ 5x = 60

    ⇒ x = 60 / 5 = 12

    So, present age of Neha's uncle = 80 - 12 = 68 years
