Step-by-step explanation
Let initial moles of reactant taken = n
Total moles obtained for benzene sulphonic acid (with % yield = 60%) = 0.6n
Moles of benzene sulphonic acid before reaction II = 0.6n
Moles obtained for phenol (with % yield = 50%) = 0.6 × 0.5n = 0.3n
So over all % yield of complete reaction
