 I am welcome to the session. Let's work out the following question. The question says, A starts a business with a capital of Rs. 4 lakhs. After 3 months B joins him with a capital of Rs. 6 lakhs and at the end of another 3 months C joins with Rs. 10 lakhs. If at the end of the year the total profit B Rs. 5,40,000 and they share it in the ratio of their effective capital, calculate the shares of A, B and C in the total profit. So let us see the solution to this question. First we find equivalent capital of A, B and C. So we see that A's equivalent capital will be Rs. 4 lakh into 12 because he has invested for the entire year. These equivalent capital is Rs. 6 lakhs into 9 because after 3 months he has joined and sees equivalent capital is Rs. 10 lakhs into 6. So ratio of equivalent capital is 4 lakh into 12 is 2, 6 lakhs into 9 is 2, 10 lakhs into 6. This ratio is same as 48 is 2, 54 is 2, 16. This ratio is further same as 8 is 2, 9 is 2, 10. Now we see that sum of the ratios is equal to 8 plus 9 plus 10 that is equal to 27. Also it is given to us in the question that total profit is Rs. 5,40,000 that is given to us. So we can say that A's share in profit is equal to 8 by 27 into 5,40,000 that is equal to Rs. 1,60,000. Now B's share in profit is equal to 9 by 27 into 5,40,000 that is equal to Rs. 1,80,000 and C's share in profit is equal to 10 by 27 into 5,40,000 and that is equal to Rs. 2 lakhs. So our answer to this question is that A's share in the profit is Rs. 1,60,000, B's share is Rs. 1,80,000 and C's share is Rs. 2 lakh. So this is our answer to this question. I hope that you understood the solution and enjoyed this session. Have a good day.
