No. of fwd path = 3.
No. of loop = 0.
No. of loop = 0.

Number of forward paths are 2.
Number of loops are 2.
That too no loop are not repeated.
The transfer function of the system is: G1G2/ (1-G1G2-G2).
Number of loops are 2.
That too no loop are not repeated.
The transfer function of the system is: G1G2/ (1-G1G2-G2).

The above answer is not correct. Number of forward path = 2.
Number of loops = 1.
Answer is [G1G2+G2]/[1-G2].
Number of loops = 1.
Answer is [G1G2+G2]/[1-G2].

There is only one loop.
Number of +ve loop = 1.
So, (G1G2 + G2) / (1 - G2).
Number of +ve loop = 1.
So, (G1G2 + G2) / (1 - G2).

Answer (G2+G1G2)/(1-G2).
Explanation:
Forward path = 2 (G2 & G1G2).
Loop = 1(G2).
Using Masson formula:
We get (G2+G1G2)/(1-G2);
Explanation:
Forward path = 2 (G2 & G1G2).
Loop = 1(G2).
Using Masson formula:
We get (G2+G1G2)/(1-G2);

If anyone knows any answer which is different from my answer please explain it clearly so that everyone will understand.

@Anish.
You are calculating TF between C and are. So there is only one forward path and that is G1G2.
