In the question, two quantities I and II are given. You have to solve both the quantities and establish the correct relation between Quantity - I and Quantity - II and choose the correct option accordingly.

'M', 'N', and 'P' are three two-digit natural numbers where the unit digit of each number is 'odd' and the ten's digit is 'even'. 'M' is the largest possible number and 'P' is the smallest possible number.

Quantity I : If all the numbers are divided by '2', then find the sum of reminders.

Quantity II : If the average of 'M', 'N', and 'P' is 51, then find the sum of digits of 'N'.
