Since the point (p, r) lies on the line with equation -

y = x + b

Substituting p for x and r for y in the equation y = x + b

gives -

r = p + b or,

b = r - p

Similarly, since the point (2p,5r) lies on the line with the equation y = 2x + b

Substituting 2p for x and 5r for y in the equation

y = 2x + b gives:

5r = 2(2p) + b

5r = 4p + b

b = 5r − 4p.

Next, we can set the two equations equal to b equal to each other and simplify:

b = r − p = 5r − 4p

3p = 4r

Finally, to find r/p

we need to divide both the sides of the equation by p and by 4 :

3p = 4r

$3 = \frac{4r}{p} \\ \\ \frac{3}{4} = \frac{r}{p}$

The correct is option B

$\frac{3}{4}$
