P and Q started a business with Rs. 6000 and Rs. 7500
respectively. Q remained in the business 4 months longer than P. If P received Rs. 1800 from the total profit of Rs. 6300, then for how many months did Q invest his money?Solution
ATQ,
Let P invested for ‘x’ months
According to question;
Or, 5×6000x=2×7500(x+4)
30000x = 15000(x+4)
30000x = 15000x+60000
15000x = 60000
x = 4
So, Q invested for (4 + 4) = 8 months
