A, B and C were partners in a firm sharing profits in 3 : 2 : 1 ratio. They admitted D for 10% profits. Calculate the new profit sharing ratio.
Existing profit sharing ratio of A, B and C is 3 : 2 : 1
D's share = 10% or 110
Let Total share = 1
Remaining share of A, B and C = 1−110=910
A's new share =910×36=2760
B's new share = 910×26=1860
C's new share = 910×16=960
New profit sharing ratio of A : B : C : D
2760:1860:960:110
or 2760:1860:960:660
or 27 18 : 9 : 6
or 9 : 6 : 3 : 2
