Maths logic problems HELP
A publisher produces magazines, all of which have a number of pages which is a multiple of 32. Thus, a magazine can have 32, 64, 96....... pages. The front cover is always counted as page 1.
The centre spread of the magazine could have pages numbered
A 15 and 16.
B 30 and 31.
C 50 and 51.
D 63 and 64.
E 96 and 97.
The centre spread of the magazine could have pages numbered
A 15 and 16.
B 30 and 31.
C 50 and 51.
D 63 and 64.
E 96 and 97.

A and D could be eliminated right away (E would be my final answer, I think)

Oh if it's multiple choice, the first page of the inner 2 will be half of a multiple of 32 i think
A 15 and 16. - Odd first number - not poss.
B 30 and 31. - 30 pages in first half = 60 pages total (not a multiple of 32)
C 50 and 51. - 20 pages in first half = 100 pages total (not multiple of 32)
D 63 and 64. - odd first num - not poss
E 96 and 97. - 96 pages first hale - 192 pages total = multiple of 32 (6x32 = 192)
think that's correct - Double first number to see if multiple of 32.
B 30 and 31. - 30 pages in first half = 60 pages total (not a multiple of 32)
C 50 and 51. - 20 pages in first half = 100 pages total (not multiple of 32)
D 63 and 64. - odd first num - not poss
E 96 and 97. - 96 pages first hale - 192 pages total = multiple of 32 (6x32 = 192)
think that's correct - Double first number to see if multiple of 32.

My mother still makes tea with the old saying:
"one spoon per person and one for the pot".
We used to buy a packet of tea every week but since grandmother came to live with us we have to buy two packets every fifth week and one otherwise.
How many people were at home before grandmother arrived?

Your looking for the biggest difference in gas bills between the months, so it's January {If the bottom numbers denote gas}.
