Here's the way I understand this:
\n" ); document.write( ":
\n" ); document.write( "two painters can paint a room in one shift of six hours.
\n" ); document.write( "determine how many man-hrs required to paint the room
\n" ); document.write( "2*6 = 12 man-hrs to complete the job
\n" ); document.write( ":
\n" ); document.write( "1.1 How long will the work shift be if four painters complete the work at the same rate?
\n" ); document.write( "let h = hrs required when 4 painter paint
\n" ); document.write( "4h = 12
\n" ); document.write( "h = 12/4
\n" ); document.write( "h = 3 hrs
\n" ); document.write( ":
\n" ); document.write( "1.2 if the room needs to be painted in a work shift of 2.4 hours, how many painters are then needed if they work at same rate as painters in 1.1
\n" ); document.write( "let m = no. of men required to do the job in 2.4 hrs
\n" ); document.write( "2.4m = 12
\n" ); document.write( "m = 12/2.4
\n" ); document.write( "m = 5 men required to accomplish this in 2.4 hrs \n" ); document.write( "

\n" );
