a business. Q's investment was 20% more than P's investment. After a year, Q earned a profit of ₹1800. How much profit did P earn?Solution
ATQ, Let the amount invested by P be Rs. ‘a’. Therefore, amount invested by Q = a + 0.20 × a = Rs. 6a/5 Ratio of the amount invested by P to Q = a:(6a/5) = 5:6 Ratio of the profit share of P to Q after 1 year = 5:6 Profit of Q after one year = Rs. 1800 Therefore, profit of P = 1800 × (5/6) = Rs. 1500
