Question

if the total of 21 of x and 20 of y is equal to 18/19 of the total of 22% of x and 24% of y what is the value of x/y ?

Answer 1

Answer:

4% of x

Step-by-step explanation:

20% of X = Y

.20(X) = Y

.20X = Y

Y = .20X

Now, multiply both sides of the last equation by 20% = .20

(.20)Y = (.20)(.20X)

.20Y = [(.20)(.20)]X

.20Y = [.04]X

.20Y = .04X

Therefore, if 20% of X is equal to Y, then 20% of Y is equal to 4% of X.

Answer 2

Correct Question

if the total of 21 %of x and 20% of y is equal to 18/19 of the total of 22% of x and 24% of y what is the value of x/y ?

Answer:

The value of  $\frac{x}{y}$ is 14.

Step-by-step explanation:

Given:

The total of 21 %of x and 20% of y is equal to 18/19 of the total of 22% of x and 24% of y.

To Find:

The value of  $\frac{x}{y}$ .

Solution:

As given-the total of 21 %of x and 20% of y is equal to 18/19 of the total of 22% of x and 24% of y.

$21\% x+ 20\% y = \frac{18}{19} ( 22\% x + 24\% y)$

$\frac{21}{100} x+ \frac{20}{100} y = \frac{18}{19} ( \frac{22}{100} x + \frac{24}{100} y)$

$21x+20y=\frac{18}{19} ( 22x+24y)$

$19(21x+20y)= 19 ( 22x+24y)$

$399x+380y=396x+432y$

$399x-396x=432y-380y$

$3x=52y$

$\frac{x}{y} =\frac{52}{3}$

$\frac{x}{y} = 14$

Thus,the value of  $\frac{x}{y}$ is 14.
