NID-DAT 2017 Bdes Answer Key with explanation


For now, I've quickly given the answers with little explanation and supportive images, If you're preparing for NID 2018, remind me to update the explanations. I've denied to many comments and messages in the blog and FB when they asked to solve this paper coz I was running out of time and busy with CEED/UCEED students.  Sorry for my previous rejections :)

Anyway, somehow managed time to cover this.

X = 32*3 - (Y+Z)

(Y+Z)/2 = 27
so Y+Z = 54

from the above
X = 32*3 - (Y+Z)
X = 32*3 - 54 = 42

They asked to average X and 2X
which will be (X+2X)/2 = 1.5*X = 63

66) C

The question has unnecessary data confusing. But the simple answer is, 
let x,y be the ages of elder and younger bros
A,B be ages of father and mother

x-y = A-B
also given that A-B = 4
when the younger has just born, i.e. y =0, so

x-0 = 4
x= 4, when his mother was 30 years
so when the elder is 4, his father is 30+4, since mom and dad age diff are only 4
whent eh elder is just born, i.e. four years back, his father will be 34-4 = 30

67) A

one possible pattern could be
sid, Baldev, Mahesh, Ram, Krish

68) D

69) C

It tells the no. of overlapped rectangles, so '?' should be 3

70) B

say x is the distance to the hill
so, to cover x km, time taken is x/20 hrs
similarlyy time taken downhill to cover same distance = x/60

Now, total distance = x+x = 2x
and total time taken = x/20+x/60 = 4x/60 = x/15

so 2x distance takes x/15 hr
x/15 hr time is needed to cover 2x distance
so, for 1 hr, distance covered = 2x/(x/15) = 30 kms

71) C

72) A

I've shown which pattern will appear in which surface for the third given cube in the question based on rest images i nthe question.

73) A, B

XI + I = X
if you turn the paper by 180 deg

you get 
X = I + IX
equating above two

XI + I = I +IX

So, if you place IX in the place of XI in the first statement, second statement will be valid, so it is possible option

74) A

75) A

B for sure denote Rabbit!


  1. Sir 34th is just mirror image joined with original text... Place finger on top half to get answer

  2. Sir 37th is wrong... Answer will be D. Answer can't be two cause it is three lettered word itself. If we read whole sentence then we will find that there are 3 3-lettered words which are 'the', 'nor' and 'are'. Correct me if I am wrong

    1. "The" is in previous sentence...
      But we answer two ...Then there are three three letter words as two itself is a three letter word

  3. Sir in Question 73
    you get the same result by rotating it by 180 degrees and by viewing it in a mirror
    So both A and B should be correct

    1. i agree with mirroring, but there isn't any option for mirror in the ques!
      Ya, it can be, I forgot to put that option too!

  4. Sir,in Q10 I think its phonograph & bulb both invented by Thomas Alva Edison.....and will we be awarded marks in Q47?

  5. We had awarded marks in q.47 by Nid or not?

  6. Sir 73rd is not possible since the Numbers are written in roman, XI is not equal to IX cuz XI means 11 and IX means 9.... Hence the statement is false.
    Answer would be C.

  7. question 27, i also got ans as C)............but they have marked it as wrong ?.........what to do

    1. dude, they marked it correct, C for 27 only, this page is for bdes, i think u r looking for mdes paper!

    2. Brother U might have saw question paper/answer paper of different code

  8. What about m.des paper??

  9. 37 is a paradoxical statement as if we write "two" there will be three three-lettered words

  10. Sir 37th is wrong... Answer will be 3. "Two" is a 3-lettered word hence it will contradict the statement. I we read the whole sentence we will find 3 3-lettered words which are "the", "nor" and "are". Hence the answer will be 3.

    1. I also have the doubt in the same question are we supposed to take both sentences into consideration

  11. What about answerkey of Mdes DAT exam???
    please can you post it....

  12. In question 50, won't it be A), considering the 4 black crosses and the white one in the negative space?

    1. I was thinking the same...as in question it isn't mentioned that you only have to identify the black crosses...if we count the white one...there would be 5

  13. I too think that 37 will be D

  14. Q59 -C ... CUT to the chase means ... Get to the point. Can you explain the choice of C ..why not A ( which has only one CUT)
