The ratio between the current age of A and B is 6:7. If B is 4 years old than A. What will be the ratio of the ages of A and B after 4 years?	Choose the correct answer:
A) 7:8	B) 8:9	C) 4:6	D) 4:8	E) 5:8
7:8   7:8   If 7:8’s age and B’s age will be 67:8 years and 77:8 years correspondingly   Then, 77:8 – 67:8 = 4   7:8 = 4   Needed ratio = (67:8 + 4) : (77:8 + 4)   = 28 : 32   = 7 : 8
