a's 1 day work = 1/16 units
\n" ); document.write( "b's 1 day work = 1/20 units
\n" ); document.write( "So, in 4 days, total work by a and b = $\"4%2A%28%281%2F16%29%2B%281%2F20%29%29\"$
\n" ); document.write( "= $\"%289%2F20%29\"$ units
\n" ); document.write( " $\"Balance+work+=+11%2F20\"$ units
\n" ); document.write( "No. of further days taken by b = $\"%2811%2F20%29%2F%281%2F20%29\"$
\n" ); document.write( "= $\"11\"$ days \n" ); document.write( "
