Logic is basically human reasoning that tells us if certain proposition or declarative statement is true.

(a)There are five boards of directors (kojo, kofi, menash musah, and mawule) of a School. The board of director kojo owns 10% shares, kofi owns 30% shares, mensah owns 20% shares, musah owns 25% shares and mawule 15% shares of the total shares. For the adoption of the particular policy to be passed in the board’s meeting more than 66% should vote in favour of the policy. The weightage to the votes depend upon the percentage shares owned by the directors. In the board’s room each director has a switch which he turns ON if votes in favour of policy. Design a switching circuit to ring a bell if policy is accepted in the board’s meeting. Only the NAND gates should be used to realize the circuit.

(b) What is a universal gate? Give examples. Realize the basic gates with any one universal gate.
