Find the largest number which should replace P in the 7-digit number 87893P4 to make the number divisible by 4.
- A8
- B9
- C2
- D0
Solution & Step-by-step Explanation
A number is divisible by 4 if the number formed by its last two digits is divisible by 4.
The last two digits of the number 87893P4 are P4.
Let's test the largest single-digit options for P:
If P=9, the last two digits are 94.
4
94
=23.5 (not divisible).
If P=8, the last two digits are 84.
4
84
=21 (divisible).
Thus, the largest digit to replace P is 8.
