Answer:
The correct answer is 5.
Explanation:
For the first circle,
When we add 6,18,12,
we get 6+18+12 = 36
Now
when we divide 36 with 6 we get 6.
again,
for second circle,
When we add 10,53,18
we get 10 + 53 + 18 = 81
when we divide 81 with 9 we get 9.
Now
let the unknown number be x.
so,
Pattern : When we add all of the number in the circle excluding the smallest number and dividing it by the smallest number we get the same number.
following the pattern,
Here in the options x>=5 (smallest number in the circle 3)
so, we can take smallest number as 5.
As the pattern,
(x+10+10)/5 = x
or, (x+20)/5 = x
or, x+20 = 5x
or, 5x-x = 20
or, 4x = 20
so, x = 5
