Then, How many for modulus-5?

Decade counter counts from 0-9 i.e 0000 to 1001.
How many FF required means 2^n FF.
Suppose if we use 3 FF i.e 2^3=8 states (000 to 111).
Decade counter means total of 10 (0 to 9).
Therefore we require 4FF (2^4=16 states).

Can anyone please explain how to find the number of flip-flops required for counters?

A decade counter is one that counts in decimal digits, rather than binary. It counts from 0 to 9 and then resets to zero. The counter output can be set to zero by pulsing the reset line low.

2^4=16and2^3=8..there for 4 flip flops needed
