Question

    The ratio of the salaries of Amit, Raj, and Dev is

    5:6:7 respectively. Sumit’s salary is 10 rupees less than Amit’s. If the difference between Dev and Amit's salary is 30 rupees, find the ratio of Raj’s salary to Sumit’s salary.
    A 15:13 Correct Answer Incorrect Answer
    B 18:13 Correct Answer Incorrect Answer
    C 13:18 Correct Answer Incorrect Answer
    D 17:14 Correct Answer Incorrect Answer

    Solution

    Let their salaries be 5x, 6x, and 7x respectively. 
    So, Sumit's salary = 5x - 10
    ATQ, 
    7x - 5x = 30 
    Or, 2x = 30 
    Or, x = 15
    So, Raj’s salary = 6 × 15 = 90 
    And, Sumit’s salary = 5 × 15 - 10 = 75 - 10 = 65
    Required ratio = 90:65 = 18:13
