Answer 1

In general, a divide by M×N counter can be realized by using the MOD-M counter followed by the MOD-N counter.

∴ Divide by 50 counter can be realized by using one MOD-5 counter followed by one MOD-10 counter or vice versa.

Analysis: For a MOD-5 counter followed by a MOD-10 counter:

The count of the MOD-5 counter will be incremented with each pulse of the incoming signal and will overflow for every 5 counts of such pulses.

The MOD-10 counter will be incremented with each time that the MOD-5 counter overflows.
The MOD-10 counter will overflow after every 10 of its counts.

∴ MOD-10 counter will overflow after every 5 × 10 = 50 pulses of the incoming signal.
