Answer:
Step-by-step explanation:
No of typists : 7
No of Hrs/day;7
No of days : 9
Total Working Hours Req for the job : 7*7*9 =441Hrs
Now,
No of typists : 3
No of Hrs/day : 3
Assume ’N’ - Required Days
So,
N* 3*3 = 441
N=49 Days

The "typist hours" are the same in both cases, which gives you an equation 7*7*9 = 3*3*days, Solve it for "days".
Answer. 49 Day's
