In The decimal 3.1de, d and e each represent a digit. If X represents the decimal 3.1de rounded to the nearest tenth, what is the value of x?
1) D=4
2) E=8
Ok, so me being the simpleton I am go through this question as follows:
1) 3.14E, Not sufficient. How could this be sufficient, you don't know what E is. In any sort of Mathematics taught from K- college 3.14 could go either way depending on E aka whether or not the hundredths digit is below or above 5. It could be 3.149, which rounds to 3.15 which rounds to 3.2 or it could be 3.141 which rounds down 3.14 which rounds to 3.1
2) Obviously not sufficient
C- obviously you have both so you know
How is this A and not c?
