If the eight-digit number 32043p88 is divisible by 4, then the maximum value of p is: Option: A.7 B.5 C.4 D.9
To determine divisibility by 4, we check the last two digits of the number.
The number is 32043p88 - the last two digits are 8 and 8, i.e. 88.
Rule: A number is divisible by 4 if its last two digits form a number divisible by 4.
Since 88 ÷ 4 = 22, remainder 0, the number is divisible by 4 for any value of p.
Hence, p can take any value from 0 to 9.
The maximum value of p = 9.
Ans: D. 9
