What is the value that must be assigned to A so that the 8-digit number 541A4888 is divisible by 9?
7
A number is divisible by 9 when the sum of its digits is divisible by 9.
Sum of digits = 5 + 4 + 1 + A + 4 + 8 + 8 + 8 = 38 + A
The multiple of 9 just above 38 is 45, so 38 + A = 45 ⇒ A = 7 (A is a single digit, and 54 would need A = 16).
Hence, the answer is 7.
