If 1.5x = 0.04y, find the value of (y - x)/(y + x).

Correct option is B

​$$\frac{36.5x}{38.5x} = \frac{36.5}{38.5}$$​​

Solution:

We are given:
1.5x = 0.04y
We need to find the value of  $$\frac{y - x}{y + x}$$​​
From the given equation:
1.5x = 0.04y
Dividing both sides by 0.04:
​$$y = \frac{1.5x}{0.04} = 37.5x$$​​
Now, substitute  y = 37.5x  into the expression   $$\frac{y - x}{y + x} :$$​​
​$$\frac{y - x}{y + x} = \frac{37.5x - x}{37.5x + x} = \frac{36.5x}{38.5x}$$​​

Thus, the value of $$\frac{y - x}{y + x}$$​ is:
​$$\frac{36.5}{38.5}$$​​
\$$\frac{y - x}{y + x} = \frac{73}{77}$$​​
