Question
A and B enter into a partnership with their initial sum
of Rs.30000 and Rs.45000 respectively. After 9 months, a third person C also joins them with his initial sum Rs.20000. After a year if total profit is Rs.4800 then find the profit share of B.Solution
Profit of A : B : C = 30000 x 12 : 45000 x 12 : 20000 x 3 = 6:9:1 Therefore, profit of B = (9/16) x 4800 = Rs.2700
