Test: Number System- 1 - Question 6

What values of A, B, C and D satisfy the following simultaneous boolean equation?

1. A = 1. B = 0, C = 0, D = 1
2. A = 1, B = 1, C= 0, D = 0
3. A = 1, B = 0, C = 1, D = 1
4. A = 1, B = 0, C = 0, D = 0

Detailed Solution for Test: Number System- 1 - Question 6

i.e. A must be 1 and B must be 0 From (ii) we have

i.e. C is also 0.
Putting the values of A, B and C in (iii)

For, the above equation to be true D is independent.

Test: Number System- 1 - Question 7

The number of 1s in the binary representation of (3* 4096 + 15*256 + 5* 16 + 3) are

Detailed Solution for Test: Number System- 1 - Question 7

3*4096 + 15*256 + 5*16 + 3
As we can see that

Hence, they only remains as same in number of 1’s and when any other number is multiplied by themselves, the number of 1 ’s is only the count of the number of 1 ’s in other multiplicant.

∴ correct option is (c)
