Question

In a certain code language, 'bright colour rainbow' is coded as 'mq bj st' and 'sunny bright day' is coded as 'nv bj fm'. How is 'bright' coded in that language?

1. A. st
2. B. mq
3. C. nv
4. D. bj (Correct answer)

Correct Answer

Option D — bj

Detailed Solution & Explanation

The correct answer is bj.

Key Points

• The word common to both phrases is 'bright', and the code common to both is 'bj'.
• Therefore 'bright' is coded as bj.

Additional Information

• Sentence-substitution codes are solved by intersection: the word appearing in both phrases must map to the code appearing in both.
• No word order is implied. The codes are deliberately scrambled, so position within the coded phrase carries no information.
• With two phrases sharing exactly one word, one common code identifies it outright. Three phrases are needed to pin down words that appear twice.
