Question

If 20% of (p+q)= 50% of (p-q) then find q as a parentage of p

Answer 1

Step-by-step explanation:

20%x(p+q) = 50%× (p-q)

0.2(p+q) = 0.5(p-q)

p+q 5

___ = ____

p-q 2

apply componendo dividendo method

if a/b = c/d, a+b/a-b = c+d/c-d

p+q+p-q 5+2

_______ = ____

p+q-p+q 5-2

2p 7

__= __

2q 3

p/q = 7/3

p=7a, q=3a

x% of 7a =3a

x% =3/7= 42.86%
