anil can do work in 10 days and babbu in 8 days.
\n" ); document.write( " anil and babbu can do the work on alternate days
\n" ); document.write( "if anil begins the work, then the work can be finished
\n" ); document.write( " in how many days
\n" ); document.write( ":
\n" ); document.write( "Let d = no. of days worked by Anil
\n" ); document.write( "and
\n" ); document.write( "(d-1) = no. of days worked by Bab
\n" ); document.write( ":
\n" ); document.write( "Let the completed job = 1
\n" ); document.write( " $\"d%2F10\"$ + $\"%28%28d-1%29%29%2F8\"$ = 1
\n" ); document.write( "Multiply by 40 to clear the denominators, results:
\n" ); document.write( "4d + 5(d-1) = 40
\n" ); document.write( "4d + 5d - 5 = 40
\n" ); document.write( "9d = 40 + 5
\n" ); document.write( "9d = 45
\n" ); document.write( "d = $\"45%2F9\"$
\n" ); document.write( "d = 5 days worked by Anil
\n" ); document.write( "and
\n" ); document.write( "4 days worked by Bab
\n" ); document.write( "so
\n" ); document.write( "It will take 9 days to complete the job
\n" ); document.write( ":
\n" ); document.write( "see if that checks out
\n" ); document.write( " $\"1%2F10\"$ + $\"1%2F8\"$ + $\"1%2F10\"$ + $\"1%2F8\"$ + $\"1%2F10\"$ + $\"1%2F8\"$ + $\"1%2F10\"$ + $\"1%2F8\"$ + $\"1%2F10\"$ = $\"5%2F10\"$ + $\"4%2F8\"$ = 1\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
