Geeta’s share of profit = 6/20, to be taken by A and B equally.
Sita gains = 6/20 X 1/2 = 6/40
Meeta gains = 6/20 X 1/2 = 6/40
New share of Sita = 7/20 + 6/40 = 14/40 + 6/40 = 20/40 = 1/2
New share of Meeta = 7/20 + 6/40 = 14/40 + 6/40 = 20/40 = 1/2
New profit ratio (Sita and Meeta) = 20 : 20 or 1 : 1
