Answer:
ritu and pooja took 30 and 40 days respectively to complete a work alone
Step-by-step explanation:
One day work of pooja = 3/4 of ritu
Then efficiency ratio of ritu : pooja = 4:3
Total efficiency = 7
Total days when work together = 120/7 days
Total work = efficiency * no. of days
Total work = 7 * 120/7 = 120
No. of days = total work / efficiency
