Question

A 500-kVA single-phase transformer "A" with a percentage impedance of 0.010+j0.05 is connected in parallel with a 250-kVA transformer "B" with a percentage impedance of 0.015+j0.04. If the transformers are serving a single-phase load rated 800 kVA, 80% lagging power factor, determine the operating power factor of transformer B. State your answer in %.
