Answer 1

Here is u r answer

Mark as Brainliest answer please my friend

Sol:-

we can take the LCM of all 3 numbers, which ends up being 60.

we can take the LCM of all 3 numbers, which ends up being 60.A does 2 work per day, and would have 60 work completed in 602 =30 days

we can take the LCM of all 3 numbers, which ends up being 60.A does 2 work per day, and would have 60 work completed in 602 =30 daysB does 3 work per day, and would have 60 work completed in 603 =20 days

we can take the LCM of all 3 numbers, which ends up being 60.A does 2 work per day, and would have 60 work completed in 602 =30 daysB does 3 work per day, and would have 60 work completed in 603 =20 daysC does 1 work per day, and would have 60 work completed in 601 =60 day

Answer 2

Answer:

let A = x/12

B=x/15

C= x/20

so, add three of them

x/12+x/15+x/20= 12x/60

so, x/5 left

they alone can do work in 5 days
