If m is an even integer, v is an odd integer, and m > v > 0, which of the following represents the number of even integers less than m and greater than v ?
A. \(\frac{m-v}{2} -1\)
B. \(\frac{m-v-1}{2}\)
C. \(\frac{m-v}{2}\)
D. \(m-v-1\)
E. \(m-v\)
Let m = 10 & v = 1...........There are 4 Even number less than 10 and greater than 1
A. \(\frac{10-1}{2} -1\)= Fraction number....
Eliminate B. \(\frac{10-1-1}{2}\) = 4.........................
KeepC. \(\frac{10-1}{2}\) = Fraction...................
EliminateD. \(10-1-1\) = 8........................................
EliminateE. \(10-1\)=9.............................................
EliminateAnswer: B
Why are we eliminating option D. Both option B and D are giving us the even integers as per the requirement. Can you explain with examples why we are eliminating D and not choosing B
