Question

If a:b = 1:2 then find the value of (3a + b): (4a + 2b).​

Answer 1

5:8

Explanation:

By question it's given that ,

`\implies a:b = 1:2`

Let us suppose that the common ratio is x , therefore the Numbers ,

`\implies a = 1x`

`\implies b = 2x`

And we need to find the value of ,

`\implies (3a + b): (4a + 2b ) \\\\\implies (3 * x + 2x ) : (4*x + 2*2x ) \\\\\implies (3x + 2x):(4x+4x)\\\\\implies 5x : 8x \\\\\implies 5:8`

Hence the required answer is 5:8 .
