To all experts:

I am newbie in electronics, I just want to ask if you have there simple schematic diagrams about 0-99 counter with using only 74LS192, 74LS47, and NE555?

Any immediate response would be highly appreciated.

Is this homework for a course?

At what speed do you need the counter to count?

Have you looked up the datasheets for these parts?
