4.
Q9. U PEOPLE PROBABLY MUST HAVE DONE THE OPENSEESAME SAMPLE

SIMILAR QUESTION AND THE INSECT WAS JUMPING IN A CIRCULAR
QUESTIONS.
Q10. Now A NEW ELEMENT.
THERE WERE2-3 VISUALIZING QUESTIONS ALSO.
A CUBE WAS GIVEN IN 1D. WITH DOTTED LINES. FACE WERE
MARKED. WITH 1 FACE AS X. U HAD TO TELL THAT WHAT WILL BE FACE OPPOSITE X WHEN
IT IS FOLDED AS A CUBE.
Q11:
DI QUES
THERE WERE AT LEAST 6-7 QUESTIONS
LINES WERE GIVEN TO INTERPRET. WHOLE LOT OF LINES THEN WE HAD TO
ANSWER 1 QUESTION BASED ON THE CONCLUSION
SOMETHING LIKE THIS(THIS QUES IS JUST A SAMPLE)
Directions for Q. 1 to Q. 5: Refer the data:
J, K, L, M and N collected stamps. They collected a total of 100
stamps. None of them collected less than 10. No two among them collected the
same number.
(i) 3 collected the same number as K and M
together.
(ii) L collected 3 more than the cube of an integer
(iii) The no. collected by J was the square of an integer.
(iv) Total no. collected by K was either the square or cube of
an integer
1. The no. collected by J was:
(1) 27 (2) 49 (3) 36 (4) 64
2. The no. collected by K was:
(1) 16 (2) 27 (3) 25 (4) 36
3. The difference of numbers collected by L & M was:
(1) 3 (2) 2 (3) 5 (4)

Solution
TCS New Aptitude Test New Delhi –Solution
Answer
in which at the center there
common part of two triangle is hexagon so from he center of the circle draw 6
triangle in hexagon.
so total there is equilateral 12 triangle
after that their find altitude of one of the main triangle that is
(sqrt(3)/4)*(a*a)=1/2 * 12(base) * altitude
so total there is equilateral 12 triangle
after that their find altitude of one of the main triangle that is
(sqrt(3)/4)*(a*a)=1/2 * 12(base) * altitude
so altitude is=6sqrt(3)
now the small triangle below
that altitude having the altitude is
(sqrt(3)/4)*(a*a) where a=4 because all 12 triangle is equilateral = 1/2 * 4(base) * altitude
(sqrt(3)/4)*(a*a) where a=4 because all 12 triangle is equilateral = 1/2 * 4(base) * altitude
sp altitude=2sqrt(3)
so diameter of
circle=6sqrt(3) + 2sqrt(3) = 8sqrt(3)
so radius is = 4sqrt(3)
so radius is = 4sqrt(3)
remaining area (ans) = pi *
r * r – 12* (sqrt(3)/4) * a * a where a=4
so ans is=67.58
2. m+d+I = 74
M=46+i+d
I=0.4*D
46+d+d0.4d+d+0.4d=74
D=10
6. APPLY PERIMETER FORMULA
2(Length+breadth)
8. A, B are common to
all Three. And another is common
1
2
3
A B
A B
A B
Now one is common in 1 and 2
One is common in 2 and
3
One is common in 3 and 1
So total no of common is
4(a+b+1+1)
9.
Calculate after 5 sec the
fly will come to no 1.
So as 5 is a factor of 60 so
fly will be in 1 after 60 min.
Directions for Q. 1 to Q. 5:
Refer the data:
L=12,N=11,J=27,M=14,K=36
Given,
K+M+J+L+N=100 ———(i)
K,M,J,L,N>10 ———(ii)
K≠M≠N≠J≠L ———(iii)
K+M=J+L+N ———(iv)
L=3 + X^3 , where X is an
integer ———(v)
J= Y^3, where Y is an
integer (Modify the question here it should be like that) ———(vi)
K=Z^2 or Z^3, where Z is an
integer ———(vii)
Now from the ques value of J
can be 27 or 64
but if we take 64 then eqn
iv would not satisfy so J=27
Again considering eqn ii, iv
& ii we can say that L+N = 23 & K+M=50
Now from eqn v the value of
L must be 11, thus L=11
That conclude N = 12
Now from the question part
3,
The difference of numbers
collected by L & M was:
(1) 3 (2) 2 (3) 5 (4) 9
Considering the fact M-L=any
of those values
Now M=L+any of those values
M=11+any of those values
Now considering each values,
M= 14, value =3; K=50-14 =36 which is a square of integer, thus satisfies
again M=13, value = 2; K=37
which is neither square or cube of any integer
M=16, value = 5; K=34 which
is neither square or cube of any integer
M=20, value = 9; K=30 which
is neither square or cube of any integer
Thus M = 14 & K = 36.
