GMAT Club Tests | M03-12

Hi Bunuel,

A small confusion with my methodology:

Answer = Total ODD numbers (100-1000) Less: numbers where the digit 5 appears

Odd numbers between 100-1000 = 450 [1000-100/2 +1]

Cases where 5 appears:

_ _ 5 = 8*9 = 72 cases
_ 5 _ = 8*4 = 32 cases
5 _ _ = 9*4 = 36 cases
i.e. total 140 cases

Hence, Answer = 450 -140 = 310!

Thanks in advance

Regards
Srinath
