Question 1048649
.
10 bulls can plough 13 hectares of farmland in 7 days. How many bulls are required to plough 115 hectares in 35 days?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
According to the condition,


{{{13/(10*7)}}} = {{{115/(x*35)}}}.


Both sides of this equation (proportion) represent the "rate-of-work" of one bull per one day.


Find x from the proportion.


x = {{{(10*7*115)/(13*35)}}} = 17.7 bulls (approximately).

Hey, my darling,


it seems that your data is wrong.


If it is so, it means I spent my time for nothing, working on your problem.


I expect at least an apology from you.
