Option 3 : $16$ days / $16$ दिन
Detailed Solution
सही उत्तर $16$ days / $16$ दिन है।
Work done in 8 days $= 8 \times (\frac{1}{24} + \frac{1}{36}) = \frac{5}{9}$. Remaining $= \frac{4}{9}$. B's time $= \frac{4/9}{1/36} = 16$ days. / 8 दिन में किया गया कार्य $= 8 \times (\frac{1}{24} + \frac{1}{36}) = \frac{5}{9}$। शेष $= \frac{4}{9}$। B का समय $= \frac{4/9}{1/36} = 16$ दिन।
