Question for Practice Questions Level 1: Coding & Decoding
Try yourself:If 'black' means 'pink', 'pink' means 'blue', 'blue' means 'white', 'white' means 'yellow', 'yellow' means 'red' and 'red' means 'brown', then what is the colour of sky?
Explanation
Sky is blue in colour and blue is the code of pink.
In these type of questions where the word 'means' is used, we use the backward method and the colour of clear sky is blue which is the code for pink.
But if the word 'called' is used (For example - blue is called white, the the colour of sky would be white), then we use the forward method.
Hence, pink is the correct answer.
