ANS 

90

GATE CSE 1998 | Question: 2.12

Function fun (x:integer):integer;
Begin
    If x > 100 then fun = x – 10
    Else fun = fun(fun (x+11))
End;

ANS

Now fun(100) = fun(fun(111)) // Since 100 is not > 100.

= fun(101) // since 111 > 100

 now this is unlike the other terms which were < 100, so we need to add 11. 

Here 101 > 100, thus we again subtract 10 from 101

→ fun = 101-10 = 91

95  ->106 
96  ->107`
97 ->108
98 ->109
99 ->110
100->111

101->91

=======

quick ANS 

100+11-10=91

99+11-10=90
