The correct option is B 262
The digits of the number inside the circle are the differences between the corresponding numbers above and below the circle.
In the first figure, 1=(2−1),3=(6−3),1=(5−4)
In the second figure, 2=(4−2),4=(6−2),8=(8−0)
Thus the digits of the missing number are (7−5),(9−3) and (3−1) i.e., 2,6 and 2.
So, the missing number is 262.
Hence, (A) is the correct answer.
