In the following question, select the number which can be placed at the sign of question mark (?) from the given alternatives.4 3 20 8 4 6 26 2 2 5 13 ?
3
Each box holds four numbers, and the aim is a single rule that links the two top numbers and the bottom-right number to the bottom-left number.
Try 'product of the two top numbers plus the bottom-right number' on Box 1: \(4\times3=12\), then \(12+8=20\), which is the bottom-left value.
Check Box 2: \(4\times6=24\), then \(24+2=26\), again the bottom-left value, so the rule holds.
Now apply it to Box 3, whose top numbers are 2 and 5 and whose bottom-left value is 13.
Compute the product first: \(2\times5=10\).
The rule requires \(10+?=13\), so \(?=13-10=3\).
Verifying the operation on two boxes before extending it to the third is what makes the answer secure.
Hence the number in place of the question mark is 3.
