20 men finished 1/4 of the house in 7 days.but they have to finish it in 5 more days. how many men shall be added to the crew so that they can finish the house?
\n" ); document.write( "----------------------------
\n" ); document.write( "# of men and # of houses completed are directly related
\n" ); document.write( "# of men and # of days required are inversely related
\n" ); document.write( "--------------
\n" ); document.write( "General Equation:
\n" ); document.write( " men = k[h/d]
\n" ); document.write( "Need to find \"k\"
\n" ); document.write( "---------------
\n" ); document.write( "Your problem:
\n" ); document.write( "20 = k[(1/4)/7]
\n" ); document.write( "k = 28*20 = 560
\n" ); document.write( "-----------------
\n" ); document.write( "Your Equation:
\n" ); document.write( "m = 560[h/d]
\n" ); document.write( "Substitute your given values of h= 3/4 of a house and d = 5 days
\n" ); document.write( "to get:
\n" ); document.write( "m = 560[(3/4)/5]
\n" ); document.write( "m = 140*3/5
\n" ); document.write( "m = 28*3
\n" ); document.write( "m = 84 (# of men to complete 3/4 th of the house in 5 days)
\n" ); document.write( "==============
