Detailed Explanation & Answer
Given:
‘617’ = Sweet and hot
‘735’ = Coffee is sweet
‘263’ = Tea is hot

Now, compare:
From 617 (Sweet and hot) and 735 (Coffee is sweet)
Common word: Sweet
Common code: 7

From 617 (Sweet and hot) and 263 (Tea is hot)
Common word: Hot
Common code: 6

From 735 (Coffee is sweet)
We already know:
Sweet = 7
So Coffee = 3 or 5
Also, from 735, remaining codes are 3 and 5

Now, from 263 (Tea is hot), and we know:
Hot = 6
So Tea = 2 or 3

So putting it together:
Hot = 6
Sweet = 7
From 735, if Sweet is 7, Coffee must be 3
So, Coffee = 3
Is = 5 (remaining word in 735)
So, for Coffee is hot → Coffee = 3, Is = 5, Hot = 6

That gives us: 3, 5, 6 → Option 3: 536

Correct answer: 3. 536 ✅
