In a certain code language, '617' means 'sweet' and 'hot'.
'735' means 'coffee is sweet'.
'263' means 'tea is hot'.
Which of the following would mean 'coffee is hot'?
1
2
3
4
Solution
From 617 → sweet, hot
From 735 → coffee, is, sweet
Common word between 617 and 735 = sweet → common digit = 7 → 7 = sweet
From 617 → hot, sweet
From 263 → tea, hot
Common word = hot → common digit = 6 → 6 = hot
From 735 → coffee, is, sweet
Already 7 = sweet
Remaining digits 3 and 5 = coffee, is
We need coffee + is + hot → digits = coffee (3 or 5), is (remaining), hot (6)
Only option containing 6 + 3 + 7 but 7 = sweet, not needed.
We need coffee + is + hot = 3,5,6 in any order.
