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?
Answer: Option
Explanation:
Let the required number of days be x.
Less cows, More days (Indirect Proportion)
Less bags, Less days (Direct Proportion)
| Cows | 1 | : | 40 |  |
:: 40 : x |
| Bags | 40 | : | 1 |
1 x 40 x x = 40 x 1 x 40
x = 40.

40 cows eat 40 bags in= 40 days
1 cow eat 40 bags in =40*40=1600 days
1 cow eat 1 bag in=1600/40=40 days
1 cow eat 40 bags in =40*40=1600 days
1 cow eat 1 bag in=1600/40=40 days

If 1 cow 1 bag in 1 day.
Then 40 cows 40 bags in 1day.
And 40 cows (40*40) bags in 40 days.
Then 40 cows 40 bags in 1day.
And 40 cows (40*40) bags in 40 days.

Simple thing is one 40cows eat 40bags in 40days.
So, that mean 1cow eating 1bag 40days..
I want to solve this problem from reverse...lets think if 1cow eat 1 bag in 1day..for 40days 40cows*40bags=1600.
Now you got it?
