    The ratio of the marks obtained by Priya, Neha, and Riya

    is 4:7:9 respectively. Sheetal scored 5 marks less than Neha. If the difference between Riya’s and Priya’s marks is 40 marks, what is the ratio of Neha’s marks to Sheetal’s marks?
    A 56:51 Correct Answer Incorrect Answer
    B 48:43 Correct Answer Incorrect Answer
    C 12:11 Correct Answer Incorrect Answer
    D 49:44 Correct Answer Incorrect Answer

    Solution

    Let marks be 4x, 7x, and 9x respectively. 
    Sheetal’s marks = 7x - 5

    ATQ, 
    9x - 4x = 40 
    Or, 5x = 40 
    Or, x = 8

    Neha = 7 × 8 = 56 
    Sheetal = 56 - 5 = 51

    Required ratio = 56:51
