I have a setup as below:

PC A --> Microtik --> C3750 --> ISP router

Both Microtik & C3750 is configured with 0.0.0.0 0.0.0.0 ISP IP static route.
This means that traffic from PC A will go to microtik, then C3750 and finally to ISP IP before going to destination.

My question is:
If i have a new device connecting to C3750, how do i configure on microtik and C3750 to ensure that PC A reaches the new device via C3750?

If you need more information, do let me know. Appreciate the kind comments. Thanks!

EDIT_1: From C3750, i can reach the new device. But i'm still unable to reach the new device from PC A or Microtik.

Post your configuration.

You are most likely missing a return route or a firewall rule to allow communications to between the 2 devices..

PC_A is behind your Mirotik which most likely using a basic firewall to protect it from any traffic that is deemed as "external" aka the internet.
