Description of Literate and Illiterate population of six villages.

 

  1. The number of literate women in village B is 39760 and that of illiterate women in village C is 25600. By what percent is the population of village B is less that that of village C?
    A)  13.07
    B) 13.25
    C)10.10
    D) 11.25
    E) 21.5
    View Answer
      Option D
    Solution:
    Literate men in village B = (8/7)*39760 = 45440
    Literate males and females = 45440 + 39760 = 85200
    If 60% ==== 85200
    then 100% ==== (85200/60)*100 = 142000
    Illiterate males in village C = (3/4)*25600 = 19200
    Illiterate population = 25600 + 19200 = 44800
    If 28% ====44800
    then 100%====(44800/28)*100 = 160000
    Therefore ,required % = (160000 – 142000)*100/160000 = 11.25
  2. If the number of literate women in village D is 32200, what is the number of illiterate population in the same village ?
    A)  48575
    B) 57042
    C)45000
    D) 54050
    E) 48300
    View Answer
      Option E
    Solution:
    Literate males in village D = (5/4)*32200 = 40250
    Total literates = 32200 + 40250 = 72450
    60%====72450
    40%====(72450*40)/60 = 48300
  3. If the population of village F is 168000, what is the number of literate males ?
    A)76800
    B) 67200
    C)45072
    D) 57480
    E) 65770
    View Answer
      Option B
    Solution:
    Literate population in village F = (168000*64)/100 = 107520
    Number of literate males = (5/8)*107520 = 67200
  4. If the illiterate female population of village E be 77000, what is the total population of that village ?
    A)  257850
    B) 331250
    C) 350000
    D) 425600
    E) 324560
    View Answer
      Option C
    Solution:
    Illiterate males in village E = (14/11)*77000 = 98000
    Total illiterate = 77000 + 98000 = 175000
    Therefore ,total population = 2 *175000 = 350000
  5. If the number of literate males in village A be 35840, the number of illiterate males in the same village ?
    A)  45022
    B) 43264
    C) 41500
    D) 40000
    E) 42781
    View Answer
      Option B
    Solution:
    Literate females in village A =(5/7)*35840 = 25600
    Total literate population = 25600 + 35840 = 61440
    48% ====61440
    52%====(61440/48)*52 = 66560
    Illiterate males = (13/20)*66560 = 43264

  9. Revolver Rani

    Maam/Sir ,
    will ibps 2017 be fully based on sbi mains 2017? or we can expect these kinds of DI’s too in the exam? because sbi mains was full of DI based on miscellaneous chapters. pls reply sbi mains troubled me a lot .. 🙁 🙁

    1. It cannot be said that whether IBPS would be fully based on SBI

      Last year it was, but cannot be said for sure
      So keep practicing such questions
      But yes this is for sure that IBPS PO will have DIs based on chapters, all DIs or some – cannot be said

      1. Navya

        mam, Mains mai chapter based DI ayegi but pre mai to calculative k hi chances hain na..;(

        1. yes pre me calculative

          but vo itne b calculative nhi hote

          like in 1 DI, we will have 5 questions, so 10 questions in 2 DIs
          from those 10 questions, you will be able to solve 7-8 very easily. Need not solve all 5 in 1 DI, leave the one in which much calculation – thats it. very simple way to crack pre
