A counter has N flip flop. The total number of states are

A counter has N flip flop. The total number of states are Correct Answer 2<sup>n</sup>

Each counter can have two states (0 or 1)

For N counter the number of states is ( 2.2.2.2.2…… n times) = 2n

E.g.

For the 2-bit counter, the number of states is 4

00, 01, 10, 11

For the 3-bit counter, the number of states is 8

000, 001, 010, 011, 100, 101, 110, 111

Each of the question below consists of a question and three statements number I, II and III given below it. You have to decide whether the data provided in the statement are sufficient to answer the question. Two person X and Y together can make 25% of total number of bricks in 4.8 days. Another person Z can make 50 bricks in a day. What is the time taken by person X and Z together to make the total number of bricks? I. Dimensions of a brick is (3cm × 4cm × 5cm) while the dimension of a cuboids when all the bricks are put together is (72cm × 80cm × 50cm) and ratio of number of days taken by X and Y alone to make the total number of bricks is 3 : 2.
