In each of the following questions two rows of number are given. The resultant number in each row is to be worked out separately based on the following rules and the question below the row is to be answered. The operations of number progress from the left to right.
Rules: (i) If an even number is followed by another even number they are to be added.
(ii) If an even number is followed by a prime number, they are to be multiplied.
(iii) If an odd number is followed by an even number, even number is to be subtracted from
the odd number.
(iv) If an odd number is followed by another odd number 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, the even number is to be
divided by odd number.
I. 12 7 16 II. 79 28 15
What is the difference between the resultants of second row and the first row ?
For the first row, we have
12 7 16
By using rule no.2 we get
12*7 = 84
84 16, Now by rule no. 1, we get
84+16 = 100
For second row
79 28 15
By rule no. 3 we have,
79-28 = 51
51 15
Now by rule no. 4 we have,
51+225 = 276.
So the difference between the two rows is
276-100 = 176.
