p, q and r are three points on the real number line where q = .

**Quantity A**:

**Quantity B**:

Explanation:

q =

qp + qr = 2pr

Divide both sides of the equation by pqr

(1/r) + (1/p) = (2/q)

(1/r) + (1/p) = (2/q)

[(1/r) + (1/p)]/2 = (1/q)<
/div>

Thus we see that (1/q) is the arithmetic mean of (1/r) and (1/p).

Thus will be greater than .

Quantity A is greater.
