tix
Length of 'Robert is
is picked up as the
in Tina's employee
employee number
character of 'Tina
length i.e. 2. So 'X​

Answer 1

Answer:

tiX

Explanation:

Length of 'Robert' is 6 and 6 is present in Robert's employ number 69737. 't is picked up as the sixth character of 'Robert Length of 'Tina' is 4 and 4 is not present in Tina's employ number i.e. 67281 so the maximum digit present in Tina's employee number which is less then it's length is 2. Hence 'T' is picked up as the 2nd charater of 'Tina'. For 'Jo' no number is present which is less then or equal to the length Le. 2. So 'X' is added to output. Hence the output is 'tiX'
