Question

If 3A = 5B – 6C, find A : B : C.​

Answer 1

Answer:

Let 3A =4B =6C be x

then A =x/3

then B =x/4

then C =x/6

Therefore, A:B:C = x/3 : x/4:x/6

= 1/3:1/4:1/6

= 1/3*12: 1/4*12: 1/6*12

= 4:3:2[L.C.M of 3,4,6 is 12]

Answer 2

Answer:

Let 3A = 5B = 6C = x, then

A = x / 3

B = x / 5

C = x / 6.

.°.A : B : C = x / 3 : x / 5 : x / 6

= 1 / 3 . 30 : 1 / 5 . 30 : 1 / 6 . 30

= 10 : 6 : 5
