  • B. 23 : 33 : 60
  • C. 20 : 22 : 40
  • D. None of these

  • Correct Answer
  • 23 : 33 : 60 

    Explanation

    Ratio of salaries
    Akash : Babloo : Cintu 2 : 3 : 5
    Let the common ratio be 'k'
    Then, salaries of Akash, Babloo and chintu will be 2k, 3k and 5k, respectively.

    Now, 15% increase in Akash's salary = 15% of 2k
    = 15 x 2k/100 = 0.3k
    New salary = 2k + 0.3k = 2.3k

    Also, 10% increase in Babloo's salary = 10% of 3k
    = 10 x 3k/100 = 0.3k
    ? New salary = 3k + 0.3k = 3.3k

    Again, 20%increase in Chintu's salary = 20% of 5k
    = 20 x 5k/100 = 1k
    New salary = 5k + k = 6k

    ? New ratio = Ratio of new salaries = 2.3k : 3.3k : 6k
    On multiplying with 10 and dividing by k ratio will be 23 : 33 : 60.
