Explanation:

Here we need to calculate $\frac{\mathrm{Total} \mathrm{Area}}{\mathrm{Mate} \mathrm{Production}}$ for states with population ≥ 13 million.

Let us start with Hawaii

$\frac{\mathrm{Total} \mathrm{Area}}{\mathrm{Mate} \mathrm{Production}}$ = $\frac{48\times 10,000}{3.5\times 1000}$ = $\frac{48}{3.5}$ × 10
    
 Here, the factor of 10 will remain the same for all states upon simplification. We just need to change the corresponding values of 48 and 3.5 for other states.
    
 Yield for Hawaii = 48/3.5 × 10 = 480/3.5 > 100 [∵ 480 > 3.5 × 100]

 Yield for Florida = 90/7.2 × 10 = 900/7.2 > 100 [∵ 900 > 7.2 × 100]

Yield for Arizona = 31/6.4 × 10 = 310/6.4 < 100 [∵ 310 < 6.4 × 100]
    
 Yield for Idaho = 33/8 × 10 = 330/8 < 100 [∵ 330 < 8 × 100]

 Yield for Kentucky = 160/11.1 × 10 = 1600/11.1 > 100 [∵ 1600 > 11.1 × 100]

 Yield for Maryland = 19/1.9 × 10 = 190/1.9 = 100 [∵ 190 = 1.9 × 100]
    
 ∴ There are 3 states for whom the ratio is > 100.

Hence, option (d).
