a,b,c together can do a piece of work in 10 days . a takes twice as long as b and c together . b takes as long as a and c together . how much time can c alone take to complete the work​

Answer»

Answer:

according to 1ST condition

a+b+c=10

according to 2nd condition

Step-by-step EXPLANATION:

  • b+c=a

now from point 1 and 2, we get

a+b+c=10

since,b+c =a

therefore we PUT VALUE of b+c as a

thus

a+a=10

2a=10

a=10÷2

thus a=5

now we substitute the value of a=5

a+b+c=10

5+b+c=10

b+c=10-5

b+c=5

according to 3rd condition b take same time as c

therefore dividing the value of b+c by 2

thus 5÷2 = 2.5

therefore c take 2.5 days ALONE
