Question
Arjun Singh invested Rs. 12,000 to start a business.
After 'M' months, Bhagat Singh joined him with an investment of Rs. 20,000. At the end of one year, the total profit was Rs. 6,100, out of which Bhagat Singh's share was Rs. 2,500. Determine the value of 'M'.Solution
Ratio of profit shares of Arjun Singh and Bhagat Singh = (12000 x 12) :{(12 - M) x 20000} = 36:(60 - 5M) Profit share of Arjun Singh = 6100 - 2500 = Rs. 3,600 ATQ; {36/(60 - 5M) } = (3600/2500) Or, 60 - 5M = 36 x (25/36) Or, 5M = 35 Or, M = 7
