Hi,

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.

**42) A**

**43) B**

Given

(X+Y+Z)/3 = 32

so,

X = 32*3 - (Y+Z)

Given

(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

**44) A**

The pattern tells that all the open crosses must be closed first, in that case transaction from 4th to 6th happen by closing the open at the bottom

**45) C**

statement (1) 762 - shoes are old

(2) 248 - grandpa is old

(3) 573 - buy good shoes

from the three, we can deduct that

2 - old [from (1) and (2)]

6 - are [only 6 left after above two which should be 'are'

**46) C**

it's like this

8 square - 5 square = 64 - 25 = 39

4 square - 1 square = 16 - 1 = 15

7 square - 4 square = 49 - 16 = 33

**47) No correct option (Ans is 15)**

Front - 3

right - 3

back - 2

left - 3

top - 3

bottom - 1

**48) A**

If you observe each pattern, that rectangle alternates in filled and empty, so pattern in R should have empty rectangle (either A or B)

and in each pattern that L shape with a bar at his head, flips and moves in opposite direction, it neither follows clock or anticlockwsie direction in each pattern. So, A suits after Q

**49) D**

**50) B**

by observation

**51) D**

Front - 1

Pretty simple, start with top left triangle numbered 1, followed by 4 or 3, after the first three, it's for sure that we have to use 5

**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

given

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

revrsing,

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

XI = 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!

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

ReplyDeleteohh ya, thanks :)

DeleteSir 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

ReplyDeleteSir in Question 73

ReplyDeleteyou 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

i agree with mirroring, but there isn't any option for mirror in the ques!

DeleteYa, it can be, I forgot to put that option too!

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

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

ReplyDeleteSir 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.

ReplyDeleteAnswer would be C.

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

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

DeleteBrother U might have saw question paper/answer paper of different code

DeleteWhat about m.des paper??

ReplyDelete37 is a paradoxical statement as if we write "two" there will be three three-lettered words

ReplyDeleteSir 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.

ReplyDeleteWhat about answerkey of Mdes DAT exam???

ReplyDeleteplease can you post it....

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

ReplyDeleteI too think that 37 will be D
