it was calculated that 75 men could complete a piece of work in 30 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 / 30 one man ’ s one day work = 1 / ( 30 * 75 ) now : no . of workers = 50 one day work = 50 * 1 / ( 30 * 75 ) the total no . of days required to complete the work = ( 75 * 30 ) / 50 = 45 answer : e"
multiply(30, divide(75, 25))
