A and B started a business with the investments in the ratio of 5 : 3 respectively. After 6 months from the start of the business, C joined and the respective ratio between the investments of B and C was 2 : 3. If the annual profit earned by them was INR 12300/- what was the difference between B’s share and C’s share in the profit
A:B = 5:3
B:C = 2:3
A:B:C = 10:6:9
Ratio of annual profit of A, B and C
=(10×12) : (6×12) : (9×6)
=20:12:9
Let the common ratio be x.
According to question,
20x+12x+9x=12300
41x=12300
x=INR 300/-
∴ Difference between B's share and C's share in the profit = 12x-9x=3x
=3x300
=INR 900/-
