9 × 2 : 9 × 9 :: 9 × 5 : ?

The correct answer is Option (2) → 9 × 6

Work out each product and compare the two numbers of the first pair: the second number is the first number with its digits reversed.

• First pair: \(9\times2=18\) and \(9\times9=81\); 81 is 18 with its digits reversed

• Second pair: \(9\times5=45\), so the missing term is 45 reversed, that is 54

• \(54=9\times6\)
