Question

If x:y=5:3,what percentage of 3x is (3x + 4y)

Answer 1

The percentage of 3x in (3x + 4y) = 55.55 %

Step-by-step explanation:

We have,

x : y = 5 : 3

To find, the percentage of 3x in (3x + 4y).

∴ x : y = 5 : 3

⇒ $\dfrac{x}{y} =\dfrac{5}{3}$

Here, x = 5 and y = 3

∴ The percentage of 3x in (3x + 4y)

= $\dfrac{3x}{(3x+4y)} \times 100$

Put  x = 5 and y = 3, we get

= $\dfrac{3(5)}{3(5)+4(3)} \times 100$

= $\dfrac{15}{15+12} \times 100$

= $\dfrac{15}{27} \times 100$

= $\dfrac{5}{9} \times 100$

= 55.55 %

Thus, the percentage of 3x in (3x + 4y) = 55.55 %
