    D Any two of them Correct Answer Incorrect Answer
    E Questions can’t be answered even after using all the information. Correct Answer Incorrect Answer

    Solution

    Let the present ages of father and daughter be F and D years respectively. A. [if gte msEquation 12]> F D+5 [if !msEquation]-->[endif]-->= `(F)/(D + 5)` = `(5)/(2)` [if gte msEquation 12]> 5 2 [if !msEquation]-->[endif]--> 2F = 5D + 20 2F – 5 D = 20 B. 2 F – 5 D = 20 C. [if gte msEquation 12]> F+ 5 D+6 [if !msEquation]-->[endif]--> = `(F + 5)/(D + 6)` = `(5)/(2)` [if gte msEquation 12]> 5 2 [if !msEquation]-->[endif]--> 2 F + 10 = 5 D + 30 2 F – 5 D = 20 Here, all the three equations are the same.
