Answer:
(C)
Step-by-step explanation:
p - q/2 = 3
p - q = 6
rp - rq = 12
r (p - q) = 12
r × 6 = 12
r = 12/6
r = 2
Given:
To find out:
Find the value of r ?
Solution:
p - q / 2 = 3
⇒ p - q = 3 × 2
⇒ p - q = 6
Now,
rp - rq = 12 [ Given ]
⇒ r ( p - q ) = 12
⇒ r ( 6 ) = 12
⇒ r = 12/6
⇒ r = 2
Hence, the value of r is 2.
