Show answer & explanation
Correct answer: A
First, determine the standard alphabetical position of each letter. For 'NOIDA', positions are N=14, O=15, I=9, D=4, A=1.
The code given is 1, 4, 9, 15, 14, which is the reverse of these positions. Similarly for 'INDIA', positions are I=9, N=14, D=4, I=9, A=1.
The code 1, 9, 4, 14, 9 confirms the pattern is reversing the standard positions.
For 'HELLO', standard positions are H=8, E=5, L=12, L=12, O=15.
Reversing this sequence gives 15, 12, 12, 5, 8.
