May Cheng and Hannah Webster are partners who share in the income equally and have capital balances of 207000 and 62500 respectively. Cheng with the consent of Webster sells one-third of her interest?

It's a statement and not a question ! From the intent of the questioner, my answer is that even after selling 1/3rd shares , the future income on residual shares would be shared on equal proportion as agreed upon between them.
