Question

Amit can do a work in 12 days and sagar in 15days if they work on it together for 4 days then the fraction of the work that is left

Answer 1

Answer: amount of work left = 8/3

Step-by-step explanation:

Work done by Amit in 1 day = 1/12

Work done by Sagar in 1 day = 1/15

Amount of work done by them TOGETHER in one day

=> 1/12 + 1/15 = ( 5+4 ) / 60 = 9/60 = 3/20

They would’ve finished the work in 20/3 days = 6.6 days approximately

They worked for 4 days

Fraction of work left = 20/3 - 4 = (20-12)/3 = 8/3

8/3 work is still left
