Two numbers x and y are such that the sum of 3% of x and 4% of y is one-third of the sum of 2% of of x and 8% of y. Find the ratio of x : y.	Choose the correct choice.
A) 3:8
B) 6:7
C) 4:7
D) 2:5
E) None of these
Explanation :   Solution: 3% of x+ 4% of y=1/3(2% of x+8% of y)   3x/100 + 4y/100 = 2x/300 + 8y/300   (3x+4y)3 = 2x+8y   7x = 4y   x/y = 4/7   Answer : 4:7
