Daniel has $160 more than Alex. After giving 1/10 of his money to
Alex, he now has 3 times as much money than Alex. How much money do they
have in the first place?

Solution: Let the Number of Dollars Alex has = x therefore , number of Dollars Daniel has = y y = x+160 ........... (1) According to question , x+160 - 1/10(x+160) = 3 (x+1/10(x+160)) x+160 (1-1/10) = 3x +3/10(x+160) x+160+(10-1)/10 = 3x +3x/10 +3*160 /10 x+160+9/10 = 3x +3x/10 +48 160+9/10 - 48 = 3x +3x/10 -x 112 +9/10 = 2x+3x/10 (112*10 + 9)/10 = (2x*10 +3x)/10 1120+9 = 20x +3x 1129 = 23x x= 1129/23 x=49.08 substitute x in first, we get y=49.08+160 =209.08 Neglecting .08 $ Therefore Alex has 49 $ and Daniel has 209$
