Amit and Ananthu can do a work in 15 days and 25 days respectively. Amit started the work and left after 3 days. Ananthu took over and completed the work. In how many days was the total work completed?
work done in 3 days =(3/25 +3/15)=24/75 rest of work =1 -24/75 Rest of the work=51/75 So anauth will done in= 51/75 *25 17 days
Amit’s 1 day’s work= 1/15
Amit’s 3 day’s work = 1/15 *3 = 1/5
Work left= 1-1/5 = 4/5
Ananthu’s one day’s work= 1/25
Ananthu can do work in = 4/5 *25 = 20 days
So total days = 25+3 = 28 days
WORK DONE BY AMIT 3/15 BALANCE OF WORK 4/5 DAYS REQUIRED TO COMPLETE THE WORK 4/5X25=20 HENCE TOTAL DAYS 3+20=23
