In a dairy farm, 40 cows eat 40 bags of husk in 40 days. In how many days one cow will eat one bag of husk?
A. 1
B. $$\frac{1}{{40}}$$
C. 40
D. 80
Answer: Option C
Solution (By Examveda Team)
Let the required number of days be x.Less cows, More days (Indirect Proportion)
Less bags, Less days (Direct Proportion)
\[\left. \begin{gathered} {\text{Cows}}\,\,\,\,\,1:40 \hfill \\ {\text{Bags}}\,\,\,\,\,40:1 \hfill \\ \end{gathered} \right\}::40:x\]
$$\eqalign{ & \therefore 1 \times 40 \times x = 40 \times 1 \times 40 \cr & \Rightarrow x = 40 \cr} $$
