Answer:
3
Step-by-step explanation:
Taking LCM of 15 and 12 = 60
Therefore the total work is taken as 60
work done by Donna = 60/15 = 4 per day.
work done by tipsy = 60/12 = 5 per day.
work done by both in a day = 5+4=9.
both worked for 5 days = 9 x 5 =45.
remaining work = 15
days required by tipsy to do remaining work = 15/5 = 3 days.
