Given: A, B and C invest capital in the ratio of 5 : 2 : 1.
A gets 20% of the total profit as his salary.
The profit share of B at the end of the year is Rs. 2000.
Concept Used: P1 :
P2 =
I1T1 :
I2T2 Here, P = Profit, I = Investment, T = Time
Calculation: Let the total profit be x.
A's profit as his salary =
× x =
The remaining profit = x -
= (
)x
The profit share of B at the end of the year is Rs. 2000.
⇒ (
)x ×
= 2000
⇒ x = 10000
The profit share of A's =
× 10000 ×
= 5000
Then, A's profit as his salary =
= 2000
Total profit of A = 2000 + 5000 = 7000
∴ Total profit of A is Rs. 7000.
