Answer 1

22 days will be taken to complete the work

Answer 2

Answer:

33 days

Step-by-step explanation:

Sine , given in the question is A and B can finish a work, working on alternative days,

17 days would be required when A works first day;

53/3 days would be required when B works first day;

So, the total days required when A and B works together would be 53/3-17

= 2 days

So, the work can be completed in 2 daus when A and B works together everyday;

Now , as per the question, C can finish the work in alone in 35 days.

So, the number of days required to complete the work given that A , B , C work together is 35 - 2

= 33 days;

So, the total days would be 33 days when A , B , C works togetherly.
