Question

if x and y vary inversely and x=25, when y =3.find y,when x=15.

Answer 1

Hey!

Let y be a

x = 25
y = 3

x = 15
y = ??

25/15 = a/3

25 × 3 = 15 × a

=> 5 = a

a = y
y = 5

Hope this helps...

Answer 2

Heya!

We have to find 'Y' , let's take 'y' as 'q'

So here is the answer-

X=25
Y= 3

x=15
q=?

As they are inversely proportional-


25/15=a/3
25×3=15×q
75=15q
75/15=q
q=5


Thus, q=5.
