Question 1207487
.
please help me to answer this question. eight men lake 12 days to cultivate a piece of land. 
after working for 3 days. six more men were employed. how long did they take to cultivate a land
~~~~~~~~~~~~~~~~~~



<pre>
After 3 days, 1/4 of the job was done; 3/4 of the job remained.


8 workers would complete the remaining job in 9 days (under regular conditions).


But 8+6 = 14 workers will complete the remaining job in  


    {{{9*(8/14)}}} = {{{(9*8)/14}}} = {{{72/14}}} = {{{36/7}}} = 5{{{1/7}}}  days.    <U>ANSWER</U>
</pre>

Solved.


Usually, in such problems, the problem composers match numbers in a way to get an integer answer.


Then the students are inspired by the beauty of a solution.
They will love &nbsp;Math.


Other &nbsp;" math composers " &nbsp;do not care about it.
Then the students consider such problems as idiotic, &nbsp;and they are right.
These students will hate &nbsp;Math.


Such math composers &nbsp;(of the second kind) &nbsp;should simply ruthlessly be kicked out of the profession
(using the method of &nbsp;" iron broom "), &nbsp;since their activity &nbsp;IS &nbsp;OPPOSITE &nbsp;to goals of education.

The solution by @josgarithmetic, giving the answer 9/7 of a day, is INCORRECT.
