1. 101010
2. 11011
3. 1011
4. 1110
5. 0001

2. 100110
3. 101010
4. 000000
5. 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.)
