In the given question, 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 question below the rows of numbers is to be answered. The operations on numbers progress from left to right. Rules :
(i) If an even number is followed by another even number, then they are to be added.
(ii) If an even number is followed by a prime number, then they are to be multiplied. (iii) If an odd number is followed by an even number, then the even number is to be subtracted from the odd number.
(iv) If an odd number is followed by another odd number, then the first number is to be added to the square of the second number.
(V) If an even number is followed by a composite odd number, then the even number is to be divided by the odd number.
`{:(84,21,13),(15,11,44):}`
What is the half of the sum of the resultants of the two rows?

Options

A. 232
B. 132
C. 116
D. 154

Answer

C

Explanation

For first row : 84 21 13
`= 84 div 21 13`
`= 4 " "13`
`4 xx 13`
= 52
So, resutant of first row = 52
For second row : 15 11 44
`= 15 + (11)^(2) 44`
`=136 + 44`
`= 180`
So, resulatant of second row = 180
Now, required number `=(1)/(2) (180 + 52) = 116`
