 Hi, and how are you all today? The question says, A, B and C are engaged in a printing business. A being the working partner receives 10% of the net profit as salary. The remaining profit is divided among themselves in the ratio 4 is to 5 is to 9. If A gets in total rupees 3 lakh, find the total profit in the business and the shares of B and C in it. So here, first of all, let the total profit be rupees X. Now, it's given to us in the question that since A is a working partner, he receives 10% of the net profit as salary. So, salary given to A is 10% of the net profit that is rupees X. So, we have the answer as rupees X by 10 that is the salary which is given to A. Now, we need to find out the remaining profit as it is what we are going to distribute among them. The remaining profit is total profit that was X minus the salary which is already being given out of it that is equal to rupees 9 X upon 10, right? Now, we are given that we need to distribute this remaining profit among A, B, 4 is to 5 is to 9. The total, the sum of the ratios is 18. So, we need to find out A's share, B's share and C's share out of this remaining profit. So, it will get multiplied by 9 X upon 10 and we have now the answer as 4 X upon 20, 5 X upon 20, 9 X upon is given to us in rupees as 3 lakh. That means his salary that was X by 10 plus his share in the remaining profit in total gives him rupees 3 lakh. So, with the help of this equation we can easily find out the value of X that is equal to plus 4 X upon 20 equal to 3 lakh. That further implies 6 X upon 20 is equal to 3 lakh. That further implies X is equal to 3 lakh into 20 upon, let us simplify it. So, we have the answer that is X, the total profit of this business as rupees 10. So, we can write down therefore total profit in the business is rupees 10 lakh. Further, we need to find out in this total profit and X values we have found out as 10 lakh. So, it is 5 upon 20 into 10 lakh and 9 upon 20 into 10 lakh. Which on simplifying will give us 50,000 that is B's share in this profit, rupees 4 lakh 50,000 that is C's share in this total profit. So, this was a required answer to this question. Hope you understood the whole concept well and enjoyed it too. Have a nice day ahead.
