A and B started a business by investing ₹10000 and ₹12000 respectively. After a year, they make a profit of ₹2200. Then, find the profit earned by A.
A's investment = ₹10000
B's investment = ₹12000
A's investment : B's investment = 10000 : 12000 = 5 : 6
A's part in the total profit = 511
In ₹2200, A's profit = 2200 × 511
⇒ ₹1000
