Rest of the work was completed by Mujahid and Mithun in 2 days How long it took to complete the whole work ?
Solution
Correct Answer: Option B
Solution:
M+M = 2 days = 3/8
M+A total work = \(\frac{{8 \times 12}}{{8 + 12}} = \frac{{24}}{5}\)
Left = 5/8 is done \(\frac{{24}}{5} \times \frac{5}{8}\) = 3
Total days = 3+2 = 5 days.
