it was calculated that 75 men could complete a piece of work in 25 days . when work was scheduled to commence , it was found necessary to send 25 men to another project . how much longer will it take to complete the work ?
"one day work = 1 / 25 one man ’ s one day work = 1 / ( 25 * 75 ) now : no . of workers = 50 one day work = 50 * 1 / ( 25 * 75 ) the total no . of days required to complete the work = ( 75 * 25 ) / 50 = 37.5 answer : c"
multiply(25, divide(75, 25))
