Short Answer Question▾

### Write in Short

The word unimpressive was given. They asked us to do change 1st & 2nd, 3rd & 4th, so on. Then they asked what will be 10th letter from right?

### Explanation

Given word is unimpressive.

u = 1 and n = 2, changing their position, n = 1 and u = 2

i = 3 and m = 4, changing their position, m = 3 and i = 4

p = 5 and r = 6, changing their position, r = 5 and p = 6

e = 7 and s = 8, changing their position, s = 7 and e = 8

s = 9 and i = 10, changing their position, i = 9 and s = 10

v = 11 and e = 12, changing their position, e = 11 and v = 12

So, word will be ‘numirpseisev’

Counting from right ‘m’ is at the 10th position.
