let father do (1/f) portion in a day  son do (1/(s ))portion in a day  so 24((1/f)+(1/s))=1  (1/f)+(1/s)=(1/(24))  in last 6 day father do (6/f) portion  remaining work (1−(6/f))  (6/f)+(6/s)=(6/(24))  (6/f)=(1/4)−(6/s)  remaining work =(1−(6/f))  =(1−(1/4)+(6/s))  =(3/4)+(6/s)  so remaining work>(3/4)
