Question

A is twice as good a workman as B and together they finish a piece of work in 14 days. In how many days can A alone do it?Please Help Me Fast​

Answer 1

Answer:

12 days

Step-by-step explanation:

We will write all works in units...

a=Ram Gopal    b=Shyam Mani

Shyam Mani does 1 unit a day

Ram Gopal does 2 unit a day(Ram Gopal works  harder than Shyam Mani so twice)

After working together = 2 + 1 = 3 units

In 14 days = 3 X 14 = 42 units

Ram Gopal does 2 units in 1/2 day

42 units in 1/2 day = 1/2 x 42 = 12 days

thank you :)
