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
