In a certain code language, BHOPAL is written as BOHAPL, and KANPUR is written as KNAUPR. How will INDORE be written in that language?

Let's analyze the pattern by pairing the letters of the words:
For BHOPAL→BOHAPL:

Positions 1 and 2: BH→BO (Wait, let's look at it as alternating or split pairs)
Let's divide into pairs of two letters:
(B,H),(O,P),(A,L)

B and O are the 1st and 3rd letters. Let's look closely at standard positions:

1
B
​

2
H
​

3
O
​

4
P
​

5
A
​

6
L
​

In the coded word BOHAPL:

B
1
​

O
3
​

H
2
​

A
5
​

P
4
​

L
6
​

The rearranged positions index is: 1,3,2,5,4,6.

Let's test this pattern on KANPUR:

1
K
​

2
A
​

3
N
​

4
P
​

5
U
​

6
R
​

Rearranging to the index 1,3,2,5,4,6:

1→K

3→N

2→A

5→U

4→P

6→R
This yields KNAUPR, which matches the given code perfectly.

Now, let's apply this exact rule to INDORE:

1
I
​

2
N
​

3
D
​

4
O
​

5
R
​

6
E
​

Rearranging according to the positional index sequence 1,3,2,5,4,6:

1→I

3→D

2→N

5→R

4→O

6→E

The resulting coded word is IDNROE.
