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 left to right. Rules. (i) If a two-digit odd number is followed by a two-digit odd number they are to be added. (ii) If a two-digit even number is followed by a two - digit odd number which is a perfect square, the even number is to be subtracted from the odd number. (iii) If a three-digit number is followed by a two-digit number the first number is to be divided by the second number. (iv) If a prime number is followed by an even number the both two are to be added. (v) If an even number is followed by another even number the both two are to be multiplied. {:(23,15,12),(X,24,49):} If X is the resultant of the first row, what is the resultant of the second row ?
