@Reya • 15 Sep, 2011 answer is 3.
@born_star16 • 16 Sep, 2011 • 1 like Answer : 6

Explanation : Looking at the diagram in rows, the central circle equals half the sum of the numbers in the other circles to the left and right of the centre.

@Reya • 16 Sep, 2011 @AKD: What is the right answer?
@Ankita Katdare • 16 Sep, 2011 Bornstar is correct. She has got the correct explanation too.

Find the number that should appear instead of the question mark.
@akhu • 27 Jun, 2012 ans pls...
@Ankita Katdare • 27 Jun, 2012 Let there be some answer guessing.
@Vanita Ladkat • 02 Jul, 2012 ans is:3
Right?
@Vanita Ladkat • 05 Jul, 2012 sure @Prashnath
i think its like :
In first row if we divide circles horizontally and adding numbers in each semicircle then finding difference between calculated addtion for first row its 5,6,7 resp for each circle
same for second row so that of 1st circle is 2 so next should be 3 so the answer
but is it right?

You mean 3 is the the difference and also the answer???
For Ex: In sec row as you said 2 is obtained by (1+7)-(2+4).
and 3 is obtained by (9+?)-(6+3). So ? is 3.

Can be a valid answer, but I think there is a solution and justifies the connection between the circles.

Anyways, good answer!!! By looking at the arrangement of the circles, it is valid!!!

Let's see what AbraKaDabra has to say.
But I think we will have to give another try, before she outs the answer.

ans is:3
Right?
Yes. 3 is the correct answer.
Using the lower two circles as a source, the values in corresponding segments of the upper left circle equal the sums of the numbers in the lower two circles. The values in the upper central circle equal the products of the values in the lower two circles, and the upper right circle equals the difference between values in the lower two circles.

ok
but mine logic was different.
Anyways i got another way of thinking from this 😀

Yes so is 3
but AKD's logic is different
And as we all knw 1 question can be solved by different ways
and different people may come up wid different logic 😀

Find the number that should appear instead of the question mark.
i think the number is 9 because in first circle 8-7=1 and 10-10=0 and (1*0=0)...same as in 2nd circle..and in 3rd circle and 4th circle if we will perform the same operation then the answer will be 12.so there is a sequence of 0,0,12,12...so the next sequece should be 0 which will be if we use 9 at the place of question mark...am i right?
@Ankita Katdare • 08 Jul, 2012 nibhani Answer is 3. Check my post #15 in this thread.
