  3. 01010101
  4. 10101101
  5. 11111111
Solution:
Binary number has only two digits i.e. 0 and 1


2. Which among the following is an appropriate binary conversion for the number 013 (which is of base 8)?
  1. 101010
  2. 11011
  3. 1011
  4. 1110
  5. 0001

3.The following image represents which logic gate?

  1. AND
  2. OR
  3. NOR
  4. NAND
  5. NOT

4. If ∆ represents ‘0’ and ○ represents ‘1’. What will be the one’s complement of - ○∆∆○○∆?
  1. 011001
  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.)
