Question and options
The highest possible value of the ratio of a four-digit number and the sum of its four digits is
- 1000
- 277.75
- 900.1
- 999
Answer and explanation
Correct answer: A - 1000
Ratio N/(digit sum) is at most 1000: 1000/1 = 1000 (also 2000/2, ..., 9000/9). Any number with a nonzero digit beyond the leading one adds to the digit sum faster than to N in relative terms (e.g., 1009/10 = 100.9). Max = 1000.
