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.

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

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

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
