    E none of these Correct Answer Incorrect Answer

    Solution

    ATQ, We can say that the present age of Mohani is = ‘m’ years  Then, the Present age of Deepika  is = (m – 6) years  So, the Present age of Shivani is  = (m – 12) years  (m - 6)/(m + 6) = 5/7 7m – 42 = 5m + 30 7m – 5m = 30 + 42 2m = 72 m = 36 So, present age Deepika is = (m - 6) = (36 - 6) = 30 yrs.
