A tank contains 10m^3 of free water, brine having a concentration of 15kgsalt/m^3 is sent into the tank at the rate of 200litres/min. The mixture is kept uniform by mixing and runs out at the rate of 100litres/min. What will be the exit brine concentration when the tank contains 15m^3 of brine

(a) Design a synchronous counter using J-K FFs that has the following sequence: 000, 010, 101, 110, and repeat. The undesired (unused) states 001, 011, 100, and 111 must always go to 000 on the next clock pulse.
(b) Redesign the counter of part (a) without any requirement on the unused states; that is, their NEXT states can be don’t cares. Compare with the design from (a).
