Given a=20 and b= 30.
Therefore answer is a=20 b=30.
Therefore answer is a=20 b=30.

Its simple as answer is B since we pass as call the function value is 20 & 30 respectively.

Since both return type doesn't match, how it is possible. Can any one explain?

It is very simple. From main function the value of a=20 and b=30.
Here the value of b=40 in function definition will be ignored.
Hence the option B is correct.
