Algebra.Com's Answer #216539 by london maths tutor(243)![]() ![]() You can put this solution on YOUR website! The truck is 2000 kg \n" ); document.write( "Load is 80% of the total weight \r \n" ); document.write( "\n" ); document.write( "Total weight = truck + load \n" ); document.write( "This means: 100% = 20%(weight of the truck) + 80%(weight of the load)\r \n" ); document.write( "\n" ); document.write( "20% --- 2000 kg \n" ); document.write( "1% --- (2000÷20)kg = 100kg \n" ); document.write( "80% ---- 80 x 100 = 8000kg \r \n" ); document.write( "\n" ); document.write( "After first stop, 1/4 of the load is discharge. \n" ); document.write( "This means, 3/4 of the load is left on the truck. \r \n" ); document.write( "\n" ); document.write( "3/4 of 8000 kg \n" ); document.write( "= 6000 kg\r \n" ); document.write( "\n" ); document.write( "The new total weight = 6000 + 2000 = 8000 kg \r \n" ); document.write( "\n" ); document.write( "Percentage of the new load = (6000/8000) x 100% = 75% \r \n" ); document.write( "\n" ); document.write( "Answer: (E) \n" ); document.write( " |
