When two numbers or quantities are Directly proportional to each other, their ratio is constant or we can write is as:
[tex] \boxed{ \rm{ \frac{x}{y} = constant}} \implies \boxed{ \rm{ \frac{x1}{y1} = \frac{x2}{y2} }}[/tex]

To FinD:
- Value of y when x = 25.....?
Step-wise-Step Explanation:
According to the relation between two numbers which are directly proportional to each other:
⇒ x1 / y1 = x2 / y2
Plugging the given values:
⇒ 50 / 180 = 25 / y2
Cross multiplying,
⇒ y2 = 180 × 25 / 50
⇒ y2 = 90
Thus, value of y when x = 25 is 90.
