In a certain code language, 'banks needs focus' means 'tg hj ws', 'banks on their' means 'ws qa nb' and 'their core' means 'nb xd'. Find the code for 'focus safe'.

'banks needs focus' means 'tgh jws'   ……….. (i) 'banks on their' means 'wsq anb'   …………. (ii) 'their core' means 'nb xd' ……….. (iii) From statement (i) and (ii), we conclude that 'banks' is coded as 'ws' From statement (ii) and (iii), we conclude that 'their' is coded as 'nb' From statement (i) alone, we conclude that 'needs' and 'focus' is coded as 'tg' and 'hj', however not necessarily on the same order. From statement (ii) alone, we conclude that 'on' is coded as 'qa. From statement (iii) alone, we conclude that 'core' is coded as 'xd' So, we cannot determine the code for 'focus safe'.
