If A:B = 2:3, B:C = 4:5 and C:D = 6:7, then find the value of A:B:C:D
Choose the correct choice from the following choices:	A) 15:24:30:35	B) 16:24:30:35	C) 17:24:30:35	D) 18:24:30:35	E) NONE OF THE ABOVE
Explanation:   A:16:24:30:35=2:3   16:24:30:35:C=4:5=(4∗3/4:5∗3/4)=3:15/4   C:D=6:7=(6∗15/24:7∗15/24)=15/4:35/8   A:16:24:30:35:C:D=2:3:15/4:35/8=16:24:30:35=8:12:9   ANSWER IS 16:24:30:35
