How many odd integers between 100 and 300 are there such that their tens digit is even?  Choose the correct choice from the following options
A) 100  B) 200  C) 300  D) 50  E) 75
I guess the easier way to do this would be.   200 numbers between - 100 and 300   Out of which half would be even, half odd.   Number of odd = 100. Of this.. the one with even tenth digit would be half again. hence 50.   correct option is 50
