    Best answer
    1. (d) 111000
      Solution:-
      The ratio of pass and fail applicants in E city = 3: 2
      The total number of applicants in E city = 1.85 lakh = 1, 85, 000
      Then, pass applicants in in E city = 1, 85, 000 x 3/5
      = 37, 000 x 3
      = 1, 11, 000

      So, total number of pass applicants in E city is 1, 11, 000.

      Hence, the correct answer is option (d) 111000.

    2. (d) D

      Solution:-
      The ratio of applicants in A city = 7: 3
      The total number of applicants in A city = 1.25 lakh => 1, 25, 000
      Then, failure applicants in A city = 1, 25, 000 x 3/10
      = 12, 500 x 3
      = 37, 500
      The ratio of applicants in B city = 5: 3
      The total number of applicants in B city = 3.14 lakh => 3, 14, 000
      Then, failure applicants in B city =3, 14, 000 x 3/8
      = 1, 17, 750

      The ratio of applicants in C city = 4: 5
      The total number of applicants in C city = 1.08 lakh => 1, 08, 000
      Then, failure applicants in C city = 1, 08, 000 x 5/9
      = 60, 000

      The ratio of applicants in D city = 1: 3
      The total number of applicants in D city = 2.27 lakh => 2, 27, 000
      Then, failure applicants in D city = 2, 27, 000 x 3/4
      = 1, 70, 250

      The ratio of pass and fail applicants in E city = 3: 2
      The total number of applicants in E city = 1.85 lakh = 1, 85, 000
      Then, failure applicants in in E city = 1, 85, 000 x 3/5
      = 37, 000 x 3
      = 1, 11, 000

      The ratio of pass and fail applicants in F city = 7: 5
      The total number of applicants in F city = 2.73 lakh = 2, 73, 000
      Then, failure applicants in in E city = 2, 73, 000 x 5/12
      = 1, 13, 375

      Then, maximum number of failure applicants in D city.

      Hence, the correct answer is option (d) D.
