Matrix based puzzle
Directions (1-4): Study the following information carefully and answer the below questions.
There is a 3*5 matrix that can produce signals which in turn help in the illumination of some bulbs. The row of the matrix is denoted by @, % and # from the bottom to top respectively and the columns are denoted by A, B, C, D and E from left to right respectively.
@ row contains a number which are consecutive multiples of 13, starting from 39 from left to right. % row contains a number which are consecutive multiples of 15, starting from 30 from left to right. # row contains a number which are consecutive multiples of 17 starting from 34 from right to left.
The matrix helps in producing signals which can be either a single string of number X or two line string X and Y. There are four lights P, Q, R and S. Based on the outcome of the string mentioned above one of the light blinks.
Condition for blink:
a) If the outcome is below 50 then P will blink
b) If the outcome range is 51-200, then Q will blink
c) If the outcome range is 201-270, then R will blink
d) If the outcome is greater than 270 then S will blink
For outcome of the string:
1) If the string has all even numbers then the outcome of the string is obtained by adding all the numbers.
2) If an odd number is followed by an even number then, the one’s place of all the two digit numbers is deleted and 10th place is multiplied to get the outcome.
3) If the string has a prime number, then the 10th place is deleted from each of the two digit numbers and the remaining numbers are multiplied.
4) If no above logic is followed then outcome is an addition of the number.
1) Which of the following bulb will illuminate for the given input
X = @B%A#A@D?
A.P will blink
B.Q will blink
C.R will blink
D.S will blink
E. Cannot be determined
2) Which of the following bulb will illuminate for the given input
X = %B@C#E%A?
A.P will blink
B.Q will blink
C.R will blink
D.S will blink
E. Cannot be determined
3) Which of the following bulb will illuminate for the given input
X = @B#E%E#A?
A.P will blink
B.Q will blink
C.R will blink
D.S will blink
E. Cannot be determined
4) Which of the following bulb will illuminate for the given input
X = @E#D@A%B?
A.P will blink
B.Q will blink
C.R will blink
D.S will blink
E.Cannot be determined
Number series conditions based
Direction (5-7): Two rows of numbers are given. The resultant number in each row is to be worked out separately based on the following rules and the question below the rows of numbers is to be answered. The operations of numbers progress from left to right.
 Step I: If an odd number is followed by an even number then the resultant will be the addition of both the numbers.
Step II:Â If an even number is followed by a perfect square then the resultant will be the subtraction of the square number from the even number.
Step III:Â If an odd number is followed by another odd number then the resultant will be the addition of both the numbers.
Step IV:Â If an even number is followed by even number then the resultant comes by multiplying the number.
Note:Â If two conditions apply for the same number then the step which comes first as in ascending order is only considered. (If 48 and 16 ->Â Step II and Step IV followed for this number so, we can take only step II)
5) Find the sum of the resultants of the two rows.

From point J, Tom takes a left turn of 16m to reach point H, which is 32m south of point C. Roy standing at point M, which is 28m west of point I. Point D is 12m south of point F and is 16m east of point B. Mike standing at point P, walks 28m towards west to reach point N.

Answers :
Directions (1-4) :
From the given data we can create the following table;
1) Answer: C
X = @B%A#A@D
X = 52 30 102 78
Here all the outcome of the string is in even number; So,
X = 52+30+102+78=262
Hence R blinks.
2) Answer: C
X = %B@C#E%A
X = 45 65 34 30
Here in the outcome of the string odd number is followed by an even number; So,
X = 4 x 6 x 3 x 3 = 216
Hence R blinks.
3) Answer: D
X = @B#E%E#A
X = 52 34 90 102
Here all the outcome of the string is in even number; So,
X = 52+34+90+102=278
Hence S blinks.
4) Answer: A
X = @E#D@A%B
X = 91 51 39 45
Here in the outcome of the string there is a prime number; So,
X = 1 x 1 x 9 x 5 = 45
Hence P blinks.
Directions (5-7) :
5) Answer: C
1st row step III applied 21+5=26; Step II applied 26-9=17
2nd row step IV applied 8×6=48; step II => 48-16=32
Sum of resultant is 32+17=49
6) Answer: E
2nd row step III 3+7=10 step IV => 10×6=60
1st row Step II 60-25=35; Step I => 35+2=37
Sum of two rows are 60+37 =97
7) Answer: D
1st row step IV => 16×2=32, step II => 32-25=7
2nd row step I => 5+8=13, step III => 13+9=22
Difference is 22-7=15
Directions (8-10) :
We have:
- Mike standing at point P, walks 28m towards west to reach point N.
- Point N is 36m north of point Q.
- Point Q is 18m east of town hall.
- Point F is 42m west of point Q, that means point F must be 24m west of town hall.
Based ontheabove given information we have:
Again, we have:
- Point D is 12m south of point F and is 16m east of point B, that means point F is 12m north of point D.
- From point M Roy walks 28m towards his left to reach point B.
- Point B is 28m south of point M.
- Roy standing at point M, which is 28m west of pointI.
Based on the above given information we have:
Again, we have:
- Point K is 12m west of point C and is 48m north of town hall, that means point K is 48m north of town hall.
- Point H is 32m south of point C.
- From point J, Tom takes a left turn of 16m to reach point H.
- Point G is 48m south of point J and is 28m east of point L, that means point J is 16m east of point H.
- Tom standing at point A, walks 12m towards east to reach point E, takes a left turn of 24m to reach point L, which means point L is 24m north of point E.
Based on the above given information we have thefinal arrangement as follow:
8) Answer: B
9) Answer: C
We have:
Clearly, Base = (24 + 16) – 28 = 12m.
Perpendicular = (28 – 12) = 16m
Shortest distance = √(162 + 122) = 20m.
10) Answer: E
