Correct Answer: 9.(3)
Solution: (3) Width of land $C$
$=600 \times \frac{5}{3}=1000$ metres
Area $=1000 \times 600$
$=600000$ sq. metre
Total area of land - A
$=600000 \times \frac{3}{2}$
$=900000$ sq. metre
Total area of land - D
$=300000$ sq. metres
Required average total earnings
Rs. $\frac{100000}{3}(6 \times 150+9 \times 10$
$200+3 \times 120$ Rs. $\frac{100000}{3}(900+1800+1200$ 360)
$=$ Rs. $\frac{100000}{3} \times 3060$
$=$ Rs. 10200000
