Answer:

3.5Ω

Explanation:

Resistance in series(Rs) = R₁ + R₂

                             Rₐ = 5Ω + 10Ω

                                  = 15Ω

                             Rᵇ = 15Ω + 20Ω

                                  = 35Ω

Resistance in parallels(1/Rp) = 1/Rᵃ + 1/Rᵇ

                                      1/Rp = 1/15Ω + 1/35Ω

                                      1/Rp = 7+3/35Ω

                                      1/Rp = 10/35Ω

                                         Rp = 35/10Ω

∴R = 3.5Ω
