Answer:
18 days
Step-by-step explanation:
More will be the number of farmers, more bighas of land will be cultivated i.e. direct proportion.
More will be farmers, less number of days will be needed i.e. indirect proportion.
According To given values,
5= k 10/9
k= 45/10 = 4.5
Now for 25 farmers bighas of land is 10.
25= 4.5 × 10/D
D= 4.5 × 10/25
D= 18 days
• Hence, 18 days will be taken.
