In a certain code,
'posing for the shoot' is coded as 'ot os zk dn' 'a game for change' is coded as 'yq sp os ge' 'the game gets ready' is coded as 'zk pk wv sp'
(all the codes are two letter coded only) What is the possible code for ‘change’?
Solution
To find the code for 'change', we use the method of elimination by comparing the given phrases. First, comparing 'a game for change' (yq sp os ge) with 'the game gets ready' (zk pk wv sp), the common word 'game' corresponds to the common code sp. Next, comparing 'a game for change' with 'posing for the shoot' (ot os zk dn), the common word 'for' corresponds to the common code os. This leaves the words 'a' and 'change' associated with the remaining codes 'yq' and 'ge'. Since there are no other sentences to further distinguish between these two, the code for 'change' could be either 'ge' or 'yq'.
