    D 28 years Correct Answer Incorrect Answer
    E 30 years Correct Answer Incorrect Answer

    Solution

    Let the age of P = x and her sister’s age = x - 7 Sister’s friend age = (x – 7) + 25 = x + 18 Ratio between the ages of P and her sister’s friend is 3:5. => x/(x+18) = 3/5 => 5x = 3x + 54 => 2x = 54 => x = 27 P’s sister age = 27 – 7 = 20 After 3 years P’s sister age = 20 + 3 = 23 years
