    What is the ratio of total number of executives recruited by organization U in the years 2007 and 2009 together to the total number of executives recruited by organization P in the same years?

    Solution

    From above table, we have

    Total number of Executives recruited by organization U in the years 2007 and 2009 = 534 + 510 = 1044

    Total number of Executives recruited by organization P in the years 2007 and 2009 = 506 + 492 = 998

    Required ratio = total number of Executives recruited by organization U in the years 2007 and 2009 : the total number of Executives recruited by organization P in the same years

    Required ratio = 1044 : 998 = 522 : 499

    Hence, the correct option is (d).
