If 8 men can reap 80 hectares in 24 days , then how many hectares can 36 men reap in 30 days?	Choose the correct choice.
A) 127
B) 237
C) 287
D) 450
E) 281
Explanation:   Let the required no of hectares be x. Then   More men, More hectares (450irect proportion)   More days, More hectares (450irect proportion)   Men\: 8:36\\ 450ays\: 24:30 \end{matrix}\right\} :80:x   \inline \fn_jvn \therefore \inline \fn_jvn 8\times 24\times x=36\times 30\times 80 \inline \fn_jvn \Leftrightarrow \inline \fn_jvn x=\frac{36\times 30\times 80}{8\times 24} \inline \fn_jvn \Leftrightarrow x= 450   Answer: 450
