Step 1: Find the average - \(\frac{10+12+q}{3} = \frac{22+q}{3}\)

Step 2: p is 3/2 the average

p = \(\frac{3}{2}*(\frac{22+q}{3}) = \frac{22+q}{2}\) -> \(p = \frac{22+q}{2}\)

Therefore, q = 2p - 22(Option C)

it's given in the question that p=3/2*(10+12+q)/3
3 is both numerator and denominator. we can clear way 3 from our calculation.
p= 1/2(22+q)
2p=22+q
2p-22=q

whic is option C .

We can create the equation:

p = (3/2) x (10 + 12 + q)/3

p =(22 + q)/2

2p = 22 + q

2p - 22 = q

Given : p = 3/2 * (10 + 12 + q)/3

means 2p = 22 + q

q = 2p - 22

(C)

Testing values

Take p = 1

1 = 3/2 * (10 + 22 + q)/3

2 = 22 + q

q = 2 - 22

q = -20

Now put p = 1 in all answer choices

Only (C) will give q = -20.

Hence (C)
