If n is an integer and 100 < n <200, what is the value

by bhumika.k.shah » Wed Jan 20, 2010 11:10 am
If n is an integer and 100 < n <200, what is the value of n?
(1) (n/36) is an odd integer.
(2) (n/45) is an even integer.


OA C but i think its B.

I know this has already been posted earlier.But there was no firm answer .
Can someone please tell me what will be the real answer .

Thanks

let me try.....

LCM of 36 and 45 is 180.

and 100 < 180 <200. so, n is 180

180/36 = 5 is an odd integer

180/45 = 4 is an even integer.

OA is C since we can't determine value of n by any one option. we need 1 and 2 to identify the value of n.

Hope, this helps.

Let me add my two cents :)

it is B..

multiples of 35 between 100 and 200
36 * 3 = 108
36 * 4 = 144
36 * 5 = 180
so it can be 108 or 180 with odd multiple

multiple of 45 between 100 and 200 is
45 * 3 = 135
45 * 4 = 180
multiple shoudl be even integer so it is sure to be 180

IMO B

Hey onedayi'll and Bhumika,

If you are talking about multiples of 36 and 45 that means you are using both the options.
I think , IMO should be C.

kewltot,

Statement II is giving u one unique answer. And so we select Answer option B

IF neither statements give u a unique answer then we go for combining these two statements and hence the answer can be C or E accordingly.

So it is B IMO

Answer should be B because n is between 100 and 200 and only 180 / 45 gives an even integer.
