Mr. rodrigues invests half his money in land, a tenth in stocks and a twentieth in bonds. He puts the remaining 35,000 in his saving account. What is the total amount of money that mr. Rodriquez saves and invests

Let's say Mr. rodrigues's total amount of money is x. 1/2 of his money is in land, 1/10 of his money is in stocks, and 1/20 of his money is in bonds. The remaining is in his savings. Therefore, 1-1/2-1/20-/10 = fraction of money in savings account = 35/100 = 7/20. If 7/20 of his money = 35000, then we can say that (7/20) x=35000, and 35000*20=7x, then getting (35000*20/7) = x, which equals (5000*20) = 100,000 dollars.
