P and Q are two partners sharing profit and losses in 3:2 ratio. They admit Y as a new partner with 1/5th share.

What will be the new profit-sharing ratio?

Why the other options don't fit:A) 12:4:7: This would imply Q lost half his proportional share while Y took a larger portion.C) 12:5:8: This swaps the ratios of Q and Y.D) 8:5:12: This suggests the new partner Y has the largest share, which is incorrect as Y was only admitted for {1}\{5}20%.
