Ramu

Step-by-step explanation:

$Total \: perimeter = 2(400+200)+4 \times 300 = 2 \times 600+1,200 = 1,200+1,200 = 2,400 \\ cost = 150 \times perimeter = 150 \times 2400 = Rs. 3,60,000 \\ Area \: of \: Rahul's \: field = 400 \times 200 = 80,000 \\no. \: of \: trees \: planed \: by \: rahul = \frac{80,000}{10} = 8,000 \\ Area \: of \: Ramu's \: field = {300}^{2} = 90,000 \\ no. \: of \: trees \: planed \: by \: ramu = \frac{90,000}{10} = 9,000$
