Question
Two friends, E and F, started a business by investing RS
1,20,000 and RS 1,80,000, respectively. They agreed to distribute their earnings in the same ratio as their investments. After a year, the profit earned was RS 4,50,000. Each of them added RS 30,000 to their respective profits and invested in a different project. If this project yielded RS 3,40,000, then E’s share in the profit is.Solution
Total =2+3=5 5 = 450000 1=90000 E=2= 90000×2=180000 F=3=90000×3=270000 Add Each of them 30000. 
17 = 3,40,000 1= 20000 Profit part of E = 7×20000= 140000 Â
