In a code language, ‘PRIGHT’ is written as ‘UFHGSN’ and ‘GARDEN’ is written as ‘OCEPBE’. How will ‘WINDOW’ be written in that language?

Solution

The logic followed here is: First, all the letters are written in reverse order. From the left end, letters in even positions are replaced by their second preceding letter while the letters at odd positions replaced by their immediate succeeding letter, as per English alphabetical series. P         R         I           G         H         T T          H         G         I           R         P + 1     -2       + 1       -2       + 1       -2 U         F          H         G         S         N So, PRIGHT is written as UFHGSN. G         A         R         D         E         N N         E         D         R         A         G + 1     -2       + 1       -2       + 1       -2 O         C         E         P         B         E So, GARDEN is written as OCEPBE. W        I           N         D         O         W W        O         D         N         I           D + 1     -2       + 1       -2       + 1       -2 X         M         E         L          J          B So, WINDOW is written as XMELJB.
