The proportion of X’s and Y’s ages is 4:5. If the difference between the current age of X and the age of Y 0.5 decades hence is 3, then what is the sum of current ages of X and Y?	Choose the most appropriate option
A) 83 years B) 39 years C) 72 years D) 48 years E) 93 years
D   72 years   We simplified the most of steps because lack of font prolem.   X = 32 years   and, Y = (5/4) x 32 = 40 years   Therefore X + Y = 40 + 32=
