Identify extreme values
Given the numbers 472, 281, 359, 816, 634: The highest number is 816 and the lowest number is 281.
Extract specific digits
The first digit of the highest number (816) is 8. The third digit of the lowest number (281) is 1.
Perform calculation
The resultant is obtained by dividing the identified first digit by the identified third digit: 8 / 1 = 8.
A: Result 2 is incorrect because the calculation 8 divided by 1 is 8. B: Result 4 is incorrect because 8 divided by 1 does not yield 4. C: Result 6 is incorrect because 8 divided by 1 does not yield 6.
D is correct because the highest number is 816 (first digit 8) and the lowest number is 281 (third digit 1), and 8 divided by 1 equals 8.
In number series questions involving comparisons, always write down the numbers in a vertical list to instantly visualize the min/max values without skipping any digits.
