Question

55 cows can graze a field in 16 days. How many cows will graze the same field in 10 days ?

Answer 1

Correct option is A. 88
Let $$x$$ be the number of cows that can graze the field in $$10$$ days.

Number of days	$$16$$	$$10$$
Number of cows	$$55$$	$$x$$

Since, the number of cows and the number of days taken by them to graze the field are in inverse variation, we have:

$$\Rightarrow$$ $$16\times 55=10\times x$$

$$\Rightarrow$$ $$x=\dfrac{16\times 55}{10}$$

$$\Rightarrow$$ $$x=88$$

$$\therefore$$ The required number of cows is $$88.$$
