Step 1: Identify the numbers in the complete (left) circle.
The left circle has top = 102, left = 09, right = 90, and bottom = 201.
Step 2: Look for a relationship between the four numbers.
Check whether the bottom number equals the sum of the other three numbers.
Top + Left + Right = 102 + 09 + 90 = 201, which is exactly equal to the bottom number, 201.
Step 3: Confirm the rule.
The rule connecting the four numbers in each circle is: Bottom = Top + Left + Right.
Step 4: Apply the rule to the incomplete (right) circle.
The right circle has top = 203, left = 07, right = 70, and the bottom value is unknown.
Using the rule: Bottom = 203 + 07 + 70 = 280.
Step 5: Match with the given options.
The value 280 corresponds to option (1). The other options, 303, 362 and 382, do not satisfy the sum rule found from the complete circle, so they are incorrect.
