Answer 1

Answer:

A+B+C done work in 16 Days

Step-by-step explanation:

Dear ,

Here is the solution

T.W = Total works = ( LCM of 30,24,20)

W/D = Work per Day

(4W/D)A+B =30 days. |

(5W/D) B+C = 24 days. | T.W = 120

(6W/D) A+C = 20 days. |

(A+B) + (B+C) + (A+C) = 15 w/ d

2(a+b+c) = 15

A+B+C = 7.5

So, (total work) / 7.5

• 120/7.5

=16

A+B+C done work in 16 Days

Hope it's help you.

Thank-you.
