Investing the corpus fund of a trust in a business

I have a scenario here,

A trust wants to invest its corpus fund in a business that is not run by it. Also, such investment would fetch the trust an amount as return on investment. Now, my question is:

          1) Whether the trust can do such kind of investment from its corpus fund without affecting its IT Exemption?

          2) Whether if the trust utilises such RoI for charity purposes, it would affect the trust's 12A regn?

Thanks & Regards,
