IF, 18/9=2 & 9/9=1 then 2/1= 2 (centre number of 1st elipse) and
24/2=12 & 36/6=6 then 12/6=2 (2nd elipse) so…
Following the same pattern of thinking,
30/5=6 & 4/2 =2 leaving 6/2=3

By this reckoning the missing number in the fianl elipse would be a 3.

(Well, not necesarily THE answer but an answer nonetheless – are there others?)

Method: Division of te numbers on the both sides of the elipse, both bottom and down and then divide the top answer by the bottom answer.

Example. in the first elipse, divide 18 by 9(which are present in either sides of the first elipse at the top) , which is 2. The next step, divide 9 by 9 (which is present in either sides of the first elipse at the bottom), which is 1. Now divide 2 by 1, which equals 2. Same is followed. for the last elipse you will get 3!

i am going to say three…..i took the top and bottom of each side of the shape, and multiplied them together, then divided the two numbers by each other, to get 2, so 30*2 divided by 5*4, would be 60/20, or 3

Jay| Guest June 3rd, 2007 - 2:39 pmThe answer is 3…

Ian Mckinnon| Guest June 3rd, 2007 - 3:14 pmtop left divided by top right times bottom left divided by bottom right.

The anwser is 3. I got the pattern in about 8 seconds.

Joe| Guest June 3rd, 2007 - 7:00 pmA—-B

—E—

C—-D

A/B=X

D/C=Y

X/Y=E

So in the first example, 18/9=2, 9/9=1, and 2/1=2.

For the last one, 30/5=6, 4/2=2, and 6/2=3. So the answer is 3.

Karl| Guest June 3rd, 2007 - 8:41 pmit may be much more simple than what i’m thinking…

“3” because the multiplier between the top two numbers divided by the multiplier between the bottom two numbers.

e.g.

18 & 9 -> 2

9 & 9 -> 1

2/1 = 2

e.g.2

24 & 2 -> 12

36 & 6 -> 6

12/6 = 2

e.g.3

30 & 5 -> 6

2 & 4 -> 2

6/2=3

Vishvas Vasuki| Guest June 4th, 2007 - 2:36 pm3 seems plausible to me.

Ian Mckinnon| Guest June 4th, 2007 - 3:36 pmI like these. you need to post more like this.

Ahmad Al-Sharman Al-Barmawi| Guest June 4th, 2007 - 7:02 pmafter some analysis…I think!!

for the first ellipse: (18/9)/(9/9)=2

for the second ellipse: (24/2)/(36/6)=2

for the third ellipse: (30/5)/(4/2)=3

so the answer is= 3

!!

Mihret K| Guest June 4th, 2007 - 7:11 pmDivide diagonals and them multiplate them? I’m not so sure… but it works:

(18/9)x(9/9)=2

(24/35)x(6/2)=2

(30/4)x(2/5)=3

So the answer should be 3

behnam| Guest June 4th, 2007 - 8:14 pm1) (18/9) / (9/9) = 2

2) (24/36) / (2/6) = 2

3) (30/4) / (5/2) = 3

The answer is: 3

RLP| Profile June 4th, 2007 - 10:37 pmYes, as many of you correctly figured out the answer is 3.

Kruzzei| Guest June 11th, 2007 - 1:46 amThis was extremely easy though.

I also get 3.
