Answer
Answer (as printed): A
Explanation
Let the total area be A million acres. Then, $$\begin{aligned} & \text { Area under Jowar }=\left(\frac{18}{360} \times A\right)=\frac{A}{20} . \\ & \text { Area under Rice }=\left(\frac{72}{360} \times A\right)=\frac{A}{5} . \\ & \frac{A}{20}=1.5 \text { million acres } \Rightarrow A=(1.5 \times 20)=30 . \end{aligned}$$ ∴ Area under rice $$=\left(\frac{1}{5} \times 30\right) \text { million acres }=6 \text { million acres. }$$
