Question

8. A and B can complete a piece of work in 5 days
and 10 days respectively. They work together
and after 2 days C joins them. The work is
now completed in 1 day. In how many days
can C alone do the work? PLZ ANSWER THE QUESTION I WILL MARK THE ANSWER AS BRAINLIST ​

Answer 1

Step-by-step explanation:

a=5days

b=10 days

and b LCM is 10

the whole work is 10

a=10/5= 2 work in a day

b=10/10 1 work in a day

a+b=3

they have two days work 3*2=6 work in 2 days remaining work is 4

now c join them

a+b+c=4

3+c=4

c=4-3

c=1

c efficiency is 1

and the whole work is 10

10/1=10

In 10 days c complete the whole work.
