If ∆ represents ‘0’ and ○ represents ‘1’. What will be
the one’s complement of - ○∆∆○○∆?
-
011001
-
100110
-
101010
-
000000
-
111111
Solution:
○∆∆○○∆ represents
100110. For finding one’s complement we change each 1 to 0 and each
0 to 1. Hence One’s complement of 100110 will be 011001. (Note:
this is not the same question as the one asked in SBI Clerk mains.)
