Detailed Solution

Given some roman numerals VX, XV, XXV and XXXV
For roman numerals, only X which equals 10, and C which equals 100, can be deducted from a roman numeral.
VX is completely meaningless because V = 5, L = 50, and D = 500 can never be subtracted from a numeral.
As a result, option 1, which is VX, is the proper choice.
Hence, option 1 is correct.
