Correct option is (2) 1/13
Applying Kirchhoff law
\(i = i_1 + i_2\) ......(1)
Apply Kirchhoff's second law first loop
\(2i + i + 2i = 2 - 1\)
\(3i + 2i_1 = 1\)
\(3(i_1 + i_2) + 2i_1 = 1\)
\(3i_2 + 5i_1 = 1\) .....(2)
Applying Kirchhoff's second law second loop
\(3i_2 + i_2 - 2i_1 = 3 - 1\)
\(4i_2 + 2i_1 = 2\) ......(3)
Solving equation (2) and (3)
\(i_1 = \frac 1{13}A\)
Reading of ammeter is \(\frac 1{13}A\).
