Wye Delta Transformation finding equivalent resistance Help

[princeofkhi]

I need help in this one Assignment Question. I have tried to solve it but could not succeed in it. After applying one transformation from wye to delta or delta to wye the circuit is getting very complicated.

Can anyone can help me in this one question?

I would be very grateful


Regards,

wye-delta transfomation can be used to reduce the number of circuit nodes in multiple steps. The circuit becomes simpler each step, the only inconvenient point is that you have to calculate transformed and parallel circuit resistor values.
