Good day.
Got this statue from my grandma. I don’t know what metal and age. Please help me 
That’s a very nice object which I’m sure would appeal to a lot of people. It does not seem to be silver so we are probably looking at some sort of base metal such as pewter or spelter. It is going to be very difficult to say for sure what metal it is without actually handling it so I suggest that you take it to a local antique dealer for an opinion.
Unless of course somebody has a check list / flow chart for remote metallurgical analysis …
