Directions (56-60): Study the following information carefully and answer the questions given below it.

There is a 5×5 matrix which can produce signals which in turn help in illumination of some bulbs. The rows of the matrix are denoted by @, %, &, £ and ¥ from bottom to top in the same order and the columns are denoted by A, B, C, D and E from left to right: ¥ row contains numbers which are consecutive multiple of „9‟ starting from „36‟.£ row contains numbers which are consecutive multiple of„13‟.& row contains numbers which are consecutive multiple of „8‟ starting from „32‟.% row contains numbers which are consecutive multiple of„7‟.@ row contains numbers which are consecutive multiple of„11‟.

Note: If the starting number of a multiple is not given; then start the row from the same number.

E g.: If a row contains numbers which are consecutive multiple of „5‟. Then the row might be as follows;

5          10        15        20        25

The matrix helps in producing signals which is a string of numbers. There are four bulbs P, Q, R and S. Based on the outcome of the string one of the bulb blinks.

1. If outcome of the string is below 80, the bulb Q blinks.
2. If outcome of the string is between 90 and 110, the bulb S blinks.

III.       If outcome of the string is between 125 and 150, the bulb P blinks.

1. If outcome of the string is between 175 and 200, the bulb R blinks.
2. If none of the above condition follows then, no bulb blinks.

For outcome of the string:

1. If all the numbers of the string is an even number then, outcome is obtained by multiplying unit digit of all the two digit numbers.
2. If a prime number is followed by another prime number then, outcome is obtained by sum of all two digits number.

III.       If a prime number is followed by a perfect square then, outcome is obtained by multiplying tenth place of all the numbers.

1. If Y = £B &E %D @D, then which of the following bulb blinks?A. R B. P C. Q D. S E. None blinks
2. If X = ¥C @D £B @B, then which of the following bulb blinks?A. R B. Q C. P D. S E. None blinks
3. If X = ¥A %D @B @D, then which of the following bulb blinks?A. S B. Q C. P D. R E. None blinks
4. If X = £E @D %A £A, then which of the following bulb blinks?A. R B. P C. Q D. S E. None blinks
5. If X = @A &E %C @B, then which of the following bulb blinks? A. R B. Q C. S       D. P E. None blinks
