In each of the following questions, 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 questions below the rows of numbers are to be answered. The operations of numbers progress from the left to the right. Rules: (i) If an odd number is followed by another composite odd number, they are to be multiplied (ii) If an even number is followed by an odd number, they are to be added. (iii) If an even number is followed by a number which is the perfect square, the even number is to be subtracted from the perfect square. (iv) If an odd number is followed by an even number, the first number is to be subtracted from the first one. (v) If an odd number is followed by an prime odd number, the first number is to be divided by the second number. 67 12 11 20 x 11 Which of the following will be the answer if the resultant of the two rows are added ? 1) 45 2) 54 3) 36 4) 18 5) None of these
