There are two rows given and to find out the resultant of a particular row we need to follow the following steps: -
STEP 1: If an even number is followed by an odd number then the resultant will be the addition of both the numbers.
STEP 2: If an odd number is followed by a perfect square then the resultant will be the difference of that square number from the odd number.
STEP 3: If an odd number is followed by another odd number (but not a perfect square) then the resultant will be the addition of both the numbers.
STEP 4: If an odd number is followed by an even number fbutnot a perfect square) then the resultant comes by zmultiplying the numbers.
STEP-5:-If an even number is followed by another even number then the resultant will be the division of first number by the second number.
If the resultant of the first row is double the resultant of the second row. Then find the value of X.
