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.

Solution / समाधान

Given:

A : B = 9 : 4

A : C = 3 : 2

To make the value of A same in both ratios, take LCM of 9 and 3.

LCM = 9

Now,

A : B = 9 : 4

Multiply A : C = 3 : 2 by 3:

A : C = 9 : 6

Therefore,

A : B : C = 9 : 4 : 6

Now multiply all terms by 3 to match the options:

= 27 : 12 : 18

Since this exact option is not given, the intended correct ratio from the given data should be:

27 : 12 : 18
