Step-by-step explanation:

p-2=q --------------- (1)

q-2=r    ∴ q=r+2 --------------- (2)

Equating both equations, we get

p-2 = r+2

r = p-2-2

r = p-4

∴ option (a) p-4=r

Answer 2

The relation between p and r is p - 4 = r

Given :

p - 2 = q and q - 2 = r

To find :

The relation between p and r is

• p - 4 = r

• p + 4 = r

• p = r

• p - 2 = r

Solution :

Step 1 of 2 :

Write down the given relations

Here it is given that

p - 2 = q - - - - - (1)

q - 2 = r - - - - - (2)

Step 2 of 2 :

Find the relation between p and r

From relation 1 we get q = p - 2

Putting the value of q in relation 2 we get

( p - 2 ) - 2 = r

⇒ p - 4 = r

⇒ r = p - 4

Hence the correct option is p - 4 = r
