Question

If x and y varies inversely as each other and x = 10 when y = 6 . Find y when x = 15.

Answer 1

Answer:

y = 4

Step-by-step explanation:

Given that x send y vary inversely,

Hence,

x × y = k (constant)

So,

Here first case x1 = 10 and y1 = 6

In, second case value of x2 = 15

Therefore ,

By the problem,

=> First Case value = Second Case value

=> x1 × y1 = x2 × y2

=> 10 × 6 = 15 × y2

=> 60 = 15 × y2

$= > y2 = \frac{60}{15}$

=> y2 = 4

Hence,

Value of y in second case is 4 (Ans)
