SOLUTION
Old Ratio (A, B and C) = 8 : 4 : 3
B retires from the firm.
His profit share = 4/15
B’s share taken by A and C in ratio of 1: 1
Share taken by A = 4/15 × 1/2 = 2/15
Share taken by C = 4/15 × 1/2 = 2/15
New Ratio = Old Ratio + Share acquired from B
A’s New Share = 8/15+2/15 = 10/15 = 2/3
C’s New Share = 3/15+2/15 = 5/15 = 1/3
∴ New Profit Ratio (A and C) = 2: 1
