Question

Can someone please help me solve?

Answer 1

Given:

• p - q/2 = 3

• rp - rq = 12

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.

Answer 2

(C)

Explanation:

p - q/2 = 3

p - q = 6

rp - rq = 12

r (p - q) = 12

r × 6 = 12

r = 12/6

r = 2
