If A : B = 2 : 3 and B : C = 4 : 5, find A : C.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 8:15.
Given:
A : B = 2 : 3
B : C = 4 : 5
Make B common:
LCM of 3 and 4 = 12
Multiply first ratio by 4 → A : B = 8 : 12
Multiply second ratio by 3 → B : C = 12 : 15
So, A : C = 8 : 15
