Select the option that will replace the question mark so that all three pairs are related in the same way.
16 : 69 :: 25 : ? :: 31 : 144
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 114
Two complete pairs are given, so find one rule that works for both, then apply it to 25. Both second numbers are a little less than five times the first.
\(16\times5=80\), and \(80-11=69\)
\(31\times5=155\), and \(155-11=144\)
So the rule is: multiply by 5 and subtract 11
For 25: \(25\times5=125\)
\(125-11=114\)
So the missing number is 114.
