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.
