Which of the following options, when placed at sign of interrogation…

The correct answer is Option (4) → \(\displaystyle\frac{\text{o}}{12}\)

The letters at the top and the numbers at the bottom follow two rules, both based on the positions of the letters in the alphabet (a = 1, ..., z = 26).

The letters (the gap grows by one each time):

• e (5) +1 → f (6), +2 → h (8), +3 → k (11), +4 → o (15)

The numbers (the letter’s position counted from z and from a, by turns):

• e: 22, its position from z (\(27-5=22\))

• f: 6, its position from a

• h: 19, its position from z (\(27-8=19\))

• k: 11, its position from a

• o: next comes the position from z, \(27-15=\) 12
