hi
gradyf,
Not likely that you will see such intensive calculations..
But if you such a Q..
Combined speed 85+10=95 words/min..
so 410400 words in \(\frac{410400}{95*60*24}\) days..
Now see if choices can help you...
4104 is a multiple of 9 as 4+1+0+4 is multiple of 9.....
4104 is also a multiple of 19 as the Denominator 95 is a multiple of 19 and NONE of the choices have 19..
also 4104 is a multiple of 8 as LAST 3 digits 104 is multiple of 8....
when you multiply 9*19*8, you realize only another 3 is required to reach 4104...
so \(\frac{19*9*8*3*100}{19*5*60*8*3}=\frac{9*10*5*2}{5*3*2*10}=3\)
ofcourse still calculations are there but slightly lesser work
