Answer 2

Answer :

We are given that,
A : B = 2 : 5
&
B : C = 3 : 4

Lets focus on the B's part,
LCM of 5 and 3 is 15.
So,
A : B = 2 : 5
=> A : B = 6 : 15 (Multiply and divide by 3)
=> A : B = 6 : 15
&
B : C = 3 : 4
=> B : C = 15:20 (Multiply and divide by 5)
=> B : C = 15 : 20,

NOW
A : B = 6 : 15
&
B : C = 15 : 20

●=> A : B : C = 6 : 15 : 20
