Correct Answer - Option 4 : Nufrit
The logic follows here is:
'bujmiz' → backbone ---(1)
'kolmiz' → kickback ---(2)
'ritbuj → barebone ---(3)
After comparing (1), (2) and (3) we get,
In statement (1) and (2) 'miz' and 'back' are common
∴ back = miz
In statement (1) and (3) 'bone' and 'buj' are common
∴ bone = buj
'Kick' and' bare' which can be separated according to remaining words.
∴ kick = kol
∴ bare = rit
Similarly,
We need 'rit', as last three alphabets choose from the option, we can see 'rit' available only in option 4.
From the above logic, we can say the meaning of threadbare is 'Nufrit'
Hence, "Nufrit" is the correct answer.
