Logical Reasoning(Master ) Ranking and ordering

Directions: 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 question below the rows of numbers is to be answered, the operation of numbers progresses from left to right.

Conditions:
(I) If an even number is followed by an odd number, then 25 is added to the difference of both numbers.
(II) If an odd number is followed by an even number, then 20 is subtracted from the sum of both numbers.
(III) If an even number is followed by an even number or an odd number is followed by an odd number, then 25 is subtracted from the product of both numbers.

Explanation:

We have,
c = 28 11 25
d = 63 18 17
Now, c = 28 11 25
Reference:
(I) If an even number is followed by an odd number, then 25 is added to the difference of both numbers.
⇒ c = [(28 – 11) + 25] 25
⇒ c = 42 25
(I) If an even number is followed by an odd number, then 25 is added to the difference of both numbers.
⇒ c = [(42 – 25) + 25]
∴ c = 52
And, d = 63 18 17
Reference:
(II) If an odd number is followed by an even number, then 20 is subtracted from the sum of both numbers.
⇒ d = [(63 + 18) – 20] 17
⇒ d = 61 17
(III) If an odd number is followed by an odd number, then 25 is subtracted from the product of both numbers.
⇒ d = [(61 × 17) – 25]
∴ d = 1012
Required Value = (d/4 - c)/3
= (1012/4 - 52)/3
= (201)/3
∴ Required Value = 67
