Previous Year Question (PYQs)



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'?





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.
