In a certain code language, 'FASHION' is written as 'NISFAHO'. How will 'BLANKET' be written in that language?

Let's analyze the pattern for the word 'FASHION' → 'NISFAHO'.
Let the indices of the original word be:

F
1
​

A
2
​

S
3
​

H
4
​

I
5
​

O
6
​

N
7
​

The coded form 'NISFAHO' corresponds to the indices:

N
7
​

I
5
​

S
3
​

F
1
​

A
2
​

H
4
​

O
6
​

First, it picks all odd positions in descending order: 7,5,3,1 (N, I, S, F).
Next, it picks all even positions in ascending order: 2,4,6 (A, H, O).

Let's apply this logic to 'BLANKET':

B
1
​

L
2
​

A
3
​

N
4
​

K
5
​

E
6
​

T
7
​

Odd positions in descending order: 7,5,3,1→T, K, A, B

Even positions in ascending order: 2,4,6→L, N, E

Combining them gives: TKABLNE.
