Answer:
Step-by-step explanation:
Work done by Murli in one day= 1/30
Work done by Srinu in one day= 1/45
Total work done by both in one day= 1/30 + 1/45 = 1/45
1/45 work is done in one day
So, total work by both is done in 45 days.
80 % of total work = 0.8 * Total work
total work= 45 days
thus, o.8 * total work= (1/45)* 0.8= 18/5 days
