# Is my circuit analysis correct in this problem?

This is the problem:

My solution:

I'm new the delta-to-y and y-to-delta transformation, it is obvious we need to use them. I got the same answer but I'm a bit skeptical about my solution.

Is my solution and analysis correct?

1. $\frac{1}{3}={0.333333…}$ in this case if you consider the result 0.3 then it will result in poor accuracy in the final result. Take at least 2 or 3 digits after decimal point like 0.33 or 0.333.
2. When applying delta-y and y-delta conversion if you find all of the three resistor with same value then use $R_y=\frac{R_d}{3}$ and $R_d = 3R_y$.
