If x is inversely proportional to y, and y = 7 when x = 16, find the value of x, when y = 2.
Correct Answer :
56
Solution :
The correct answer is 56.
Step 1: Understand the relationship between x and y.
When two variables and are inversely proportional, their product is equal to a constant, .
This inverse variation relationship can be written as:
or equivalently:
Step 2: Find the constant of proportionality (k).
We are given that when .
Substitute these values into the formula to find :
Step 3: Calculate the value of x when y = 2.
Now, we use the constant and the given value to find the new value of :
Divide both sides by 2:
Thus, when , the value of is 56.
