Question
In a business, A invested Rs. 1800 more than that by B.
After 10 months, A left the business. If at the end of the year, profit earned by B is equal to the profit earned by A, then find the amount invested by A in the business.Solution
Let the amount invested by B be Rs.x. According to question, => x × 12 = (x + 1800) × 10 => 12x = 10x + 18000 => 2x = 18000 => x = 9000 Amount invested by A = 9000 + 1800 = Rs.10800
