Answer 1

Answer

Answer is 6 days.

Step-by-step explanation:

Let shashanks work be x,sargurs be y and z harshas be z.

given 1/x+1/y=1/3.......(1)

1/y+1/z=1/6........(2)

1/z+1/x=1/12........(3)

add all equations we will get

2[1/x+1/y+1/z]=7/12

=1/x+1/y+1/z=7/6( using equation 2)

we get 1/x=1/6.

Therefore, shashank alone can complete the work in 6 days.☺️☺️☺️
