y varies directly

Therefore y=kx

where k is a constant

when y is 12 and x is d

k=y/x = 12/d

when x is 2

y=12/d x 2

y=24/d

Therefore y=kx

where k is a constant

when y is 12 and x is d

k=y/x = 12/d

when x is 2

y=12/d x 2

y=24/d

Y=12 , X=d , k=?

12/d=k

Y when X=2

since X=d and k=12/d ,

k=12/2=6

to find Y

Y=kX

k=6 ,X=2

Y=6*2=12

ans=12
