Question

p and q are directly proportional find q if P is 10. given that p:q = 2:7​

Answer 1

x=ky

where k is the constant of variation.

Here, it is given that p varies as q if p=5 and q=10, therefore,

p=kq

⇒5=k×10

⇒5=10k

⇒k=

10

Thus, the general equation is p=

q.

Since p=20, therefore,

p=

q

⇒20=

1

q

⇒q=20×2=40

Hence, q=40 when p=20.

Answer 2

Answer:

quick is equal to 40 p is equal to 20
