In the following question, select the number which can be placed at the sign of question mark (?) from the given alternatives. 3 4 17 5 4 2 14 6 5 2 13 ?
3
This is a missing-number (diagram) problem: within each box, three of the numbers combine to produce the fourth by one repeated rule.
Label each box by its top pair and its two lower numbers. Test the rule: (top-left × top-right) + bottom-right = bottom-left value.
Box 1: \(3 \times 4 = 12\), then \(12 + 5 = 17\), matching the given 17.
Box 2: \(4 \times 2 = 8\), then \(8 + 6 = 14\), matching the given 14.
So the rule holds: product of the top two numbers plus the bottom-right number gives the remaining number.
Box 3: \(5 \times 2 = 10\), and this must satisfy \(10 + ? = 13\), so \(? = 3\).
The key concept is confirming a single multiply-then-add relationship on the solved boxes before applying it. Hence the missing number is 3.
Choose the correct alternative to replace the question mark (?).
