In the following question, select the number which can be placed at the sign of question mark (?) from the given alternatives.4 5 2 14 4 6 3 22 4 ? 2 12
4
Each box has a top row of two numbers and a bottom row of two numbers, and the same rule links them in every box.
Box 1 has top numbers 4, 5 and bottom numbers 2, 14. Box 2 has top numbers 4, 6 and bottom numbers 3, 22.
Test the rule: bottom right number = (top right number) x (bottom left number) + (top left number).
For Box 1: \(5\times 2 + 4 = 10 + 4 = 14\), which matches.
For Box 2: \(6\times 3 + 4 = 18 + 4 = 22\), which also matches.
Apply the same rule to Box 3, where top numbers are 4, ? and bottom numbers are 2, 12: \(? \times 2 + 4 = 12\).
So \(? \times 2 = 12 - 4 = 8\), giving \(? = 4\).
Hence the number in place of the question mark is 4.
