A+B can complete
while btc can complete the same work in 60% lesser
time than A, if they together can complete the whole
work in zo days, then in how many days
will they
alone complete the same work.​

Answer 1

Step-by-step explanation:

a+b

b+c can complete=60 %less time

together , b+c = 2 days

according to question

b+c=60%

therefore a= 100%- 60%

= 40%

so,b= 60%

now

b+c=60/30

=2

so,a =1day

therefore the work might be completed by each one in3 days.
