Directions (1 – 5): Study the following information carefully and answer the questions given below.
There is 3*5 matrix which can produce signals which in turn help in the illumination of some bulbs. The row of the matrix are denoted by $, & and * from bottom to top and the columns are denoted by the alphabets P, Q, R, S and T from left to right.
$ row contains number which are consecutive multiple of 7, staring from 28 (from left to right).
& row contains numbers which are consecutive multiple of 11, starting from 11 (from left to right).
* row contains number which are consecutive multiple of 13, starting from 13 (from left to right).
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 4 lights A, B, C and D. Based on the outcome of the strings mentioned above one of the light blinks.
Condition for blink:
1. If the outcome is below 85, then A will blink
2. If outcome range is 85-110, then B blinks
3. If outcome range is 111-210, then C blinks
4. If outcome is greater than 210, then D blinks
For outcome of the string:
1. If the string has all even numbers, then 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 places of all the two-digit numbers are deleted and, tenth place are multiplied to get the outcome
3. If the string contains 2 prime number, then the tenth’s place is deleted from each of the two-digit number and remaining number are multiplied.
4. If no above logic is followed, then simple outcome is addition of the numbers.

D. C
E. Either A or B
4. If X = $P *Q $S &R, then which bulb blink?
A. D
B. B

E. Either C or D
Answers and Explanations
1. Answer - Option C
Explanation -
For matrix formation:
There is 3 × 5 matrix.
The row of the matrix are denoted by $, & and * from bottom to top and the columns are denoted by the alphabets P, Q, R, S and T from left to right.
$ row contains number which are consecutive multiple of 7, starting from 28 (from left to right).
& row contains number which are consecutive multiple of 11, starting from 11 (from left to right).
* row contains number which are consecutive multiple of 13, starting from 13 (from left to right).
X = *R &S *P *T
X = 39 44 13 65
Condition 2 is applicable here: If an odd number is followed by an even number then the one’s places of all the two-digit numbers are deleted and, tenth place are multiplied to get the outcome
X = 3 × 4 × 1 × 6 = 72
As the outcome is below 85, hence bulb A will blink.
2. Answer - Option D
Explanation -
X = $P $R *S &Q
X = 28 42 52 22
Condition 1 is applicable here: If the string has all even numbers, then outcome of the string is obtained by adding all the numbers.
X = 28 + 42 + 52 + 22 = 144
As the outcome of the string is between 111 – 210, hence bulb C will blink.
3. Answer - Option C
Explanation -
X = *P &T &P $Q
X = 13 55 11 35
Condition 3 is applicable here: If the string contains 2 prime number, then the tenth’s place is deleted from each of the two-digit number and remaining number are multiplied.
X = 3 × 5 × 1 × 5 = 75
As the outcome is below 85, hence bulb A will blink.
4. Answer - Option D
Explanation -
X = $P *Q $S &R
X = 28 26 49 33
Condition 4 is applicable here: If no above logic is followed, then simple outcome is addition of the numbers.
X = 28 + 26 + 49 + 33 = 136
As the outcome of the string is between 111 – 210, hence bulb C will blink.
5. Answer - Option A
Explanation -
X = $T *S $S *T
X = 56 52 49 65
Condition 4 is applicable here: If no above logic is followed, then simple outcome is addition of the numbers.
X = 56 + 52 + 49 + 65 = 222
As the outcome of the string is greater than 210, hence bulb D will blink.
