a:b:C = 3:4:7

a/b =3/4

b/c =4/7

implies a = 3/4b

& c= 7/4b

substiute in c-a = 12 we will get value of b and accordinlgy all values and add them

so both are rquired to answer it ......... it should be C both stats together are suiffcient

could u tell me what is the correct answer

But when we add all together we get a final value of 2C.....which can vary based on the value of C right.....how can C be the answer
