(1) The product of the number of pencils Xavier and Zara have is 40.
(2) Zara has more than 6 pencils.

X + Z = 13

(1) The product of the number of pencils Xavier and Zara have is 40.
X*Z = 40
Two cases (X, Z) = (8, 5) or (5, 8)
—> 2 ratios are possible —> Insufficient

(2) Zara has more than 6 pencils
—> Insufficient

Combining (1) & (2),
(X, Z) = (5, 8)
—> Required Ratio = X:Z = 5:8 —> Sufficient

IMO Option C
