Question

A b and c can finish a work in 10 12 and 15 days respectively. They start woring together. If b stops after 2 days , how long would it take for a and c

Answer 1

Answer:

7 days

Step-by-step explanation:

Let the total work be completed in "x" days.

Therefore,

A worked for (x-5) days

B worked for (x-5+2) = (x-3) days

C worked for x days

Now,

(x-5)/10 + (x-3)/12 + x/15 = 1

Solving the above equation, we get "x" = 7

Hence, total time taken to complete the work is 7 days.
