In the following circuit, X is given by GATE ECE 2007 Digital Circuits - Combinational Circuits Question 28 English

$$X = \,A\overline B \,\overline C + \overline A \,B\,\overline C + \overline A \,\overline B C + ABC$$

$$X = \,\overline A \,BC + A\overline B C + AB\overline C + \overline A \,\overline B \,\overline C $$

$$X = AB + BC + AC$$

$$X = \,\overline A \,\overline B \, + \overline B \,\overline C \, + \overline A \,\overline C $$

GATE ECE 2007 Digital Circuits - Sequential Circuits Question 26 English

P = 1, Q = 0; P = 1, Q = 0; P = 1, Q = 0 or P = 0, Q = 1

P = 1, Q = 0; P = 0, Q = 1; or P = 0, Q = 1; P = 0, Q = 1

P = 1, Q = 0; P = 1, Q = 1; P = 1, Q = 0 or P = 0, Q = 1

P = 1, Q = 0; P = 1, Q = 1; P = 1, Q = 1
