Correct Answer - Option 5 : 141225181522
Logic: Position of the reverse letter in the alphabetical series.
Consider A → 1, B → 2, C → 3, D → 4 and so on...
PILLOW = 11181515124
P → 16 (27 - 16 = 11)
I → 9 (27 - 9 = 18)
L → 12 (27 - 12 = 15)
L → 12 (27 - 12 = 15)
O → 15 (27 - 15 = 12)
W → 23 (27 - 23 = 4)
Similarly,
M → 13 (27 - 13 = 14)
O → 15 (27 - 15 = 12)
B → 2 (27 - 2 = 25)
I → 9 (27 - 9 = 18)
L → 12 (27 - 12 = 15)
E → 5 (27 - 5 = 22)
Implies MOBILE = 141225181522
Hence, the correct answer is 141225181522.
