Correct option is D
Given:
Number = 28P3
The number is divisible by 11.
Formula Used:
A number is divisible by 11 if the difference between the sum of its digits at odd places and the sum of its digits at even places is either 0 or a multiple of 11.
Solution:
Find the sum of digits at odd places (1st and 3rd from left):
2 + P
Find the sum of digits at even places (2nd and 4th from left):
8 + 3 = 11
Set the difference equal to 0 for divisibility:
11 - (2 + P) = 0
9 - P = 0
P = 9
Final Answer
So the correct answer is (d)
