Answer:
35% of land is used for grazing.
Step-by-step explanation:
It is given that:
Percent of land used to plant beans = 40%
Percent of land used to plant maize = 25%
Let,
x be the percent of land used for grazing.
100% be the total percent.
40% + 25% + x = 100%
65% + x = 100%
x = 100% - 65%
x = 35%
Thus,
35% of land is used for grazing.
