Question

If x varies directly as y & x= 20 when y = 25,then y= ____ when x=32​

Answer 1

Answer:

40

Step-by-step explanation:

20:25::32:y

product of extremes= product of means

  20y=25x32

    20y=800

   y= 800/20

     40

y = 40 when x=32

Answer 2

Answer:

Since x is directly proportional to y,

Therefore, x/y=Constant

x1=20, y=25

x2=32, y=?

Therefore, x1/y1=x2/y2

=>20/25=32/y2

=>4/5×32=1/y2=1//5×8=1/40

=>1/y2=1/40

=> y2= 40
