\n" ); document.write( "Person A can complete work in 1 hour = 1/4 part\r
\n" ); document.write( "\n" ); document.write( "Person B can complete work in 1 hour = 1/6 part\r
\n" ); document.write( "\n" ); document.write( "Total work that can be done in 1 hour if both work together = 1/4 +1/6
\n" ); document.write( "
\n" ); document.write( " = 5/12 part.\r
\n" ); document.write( "\n" ); document.write( "Time required to complete the work = 12/5 hours\r
\n" ); document.write( "\n" ); document.write( "By formula u can solve in this way : A*B/ (A+B)\r
\n" ); document.write( "\n" ); document.write( "= 4*6 /(4+6)\r
\n" ); document.write( "\n" ); document.write( "= 24/10 = 12/5 hours. \r
\n" ); document.write( "\n" ); document.write( "I hope it will help u to understand the solution.
