If m : n = 3 : 4 and n : o = 8 : 9, then m : o is :
Choose the correct choice from the following answers:
A) 1 :3  B) 3 :2  C) 2 : 3  D) 1 : 2  E) None of these
Expl : m/n = m/n * n/o =3/4 * 8/9 = 2/3. So m : o = 2 : 3   Answer :2 : 3
<result>C</result>
If m : n = 3 : 4 and n : o = 8 : 9, then m : o is :
