A, B and C are sections of Class X. The ratio of A : B is 9 : 4 and that of A : C is 3 : 2. Find A : B : C.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 9 : 4 : 6
A : B = 9 : 4
A : C = 3 : 2
L.C.M of A values = 9
Multiply second ratio by 3 → A : C = 9 : 6
Now A : B = 9 : 4, A : C = 9 : 6
So, A : B : C = 9 : 4 : 6
