Solution :

Given :

• ‘HOST’ is coded as ‘9724’,
• ‘KINDO’ is coded as ‘45310’,
• ‘KNOWS’ is coded as ‘37654’.

‘KNOWS’ and ‘KINDO’ -> KNO are common letter, therefore remove common number 3,5,4
‘KNOWS’ and ‘HOST’ -> OS are common letter, therefore remove common number 4,7

Remaining letter in ‘KNOWS’ is W and remaining number is 6
