Who solves correctly, will be brainliest.

Answer 1

Suppose A, B and C take x, x/2 and x/3 respectively to finish the work.
Then, (1/x + 2/x + 3/x) = 1/2
6/x = 1/2 => x = 12
So, B takes 6 hours to finish the work.

Answer 2

Hi friend,

Let us take A,B,C be x, x/2,x /3 respectively.

Given,

X+2x +3x =2
Taking reciprocal on both the sides,

x +x/2 + x/3 = 1/2

x+ 2/x +3/x = 1/2

6/x =1/2
x=12

Sub.in "B",

X/2 = 12/2 => 6 days.

:-(B) is the correct answer.

Hope this helped you a little!!!
