Question

If a:b:c=3:4:7, then the ratio (a+b+c):c is equal to
A) 2:1
B)14:3
C)7:2
D1:2
​

Answer 1

Answer:

2:1

Step-by-step explanation:

Let a =3x

   b=4x

  c=7x

Hence---->(a+b+c):c

           =(3x+4x+7x):7x

          =14x:7x

         =2:1

Answer 2

Take the values as X
Now for a which is equal to 3x
B is equal to 4x
C is equal to 7x
Now to the next equation
(3x+4x+7x):7x
(14x):7x
Further it will be equal to 2:1
Hope it helps
