A can do a piece of work alone in 32 days, while together with B she can do the work in 24 days. If C alone can do the work in 64 days, in how many days can B and C together do the work?
38 \( \frac{2}{5} \) days
38 \( \frac{3}{5} \) days
37 \( \frac{4}{5} \) days
38 \( \frac{4}{5} \) days
Solve the following.
108 ÷ (36 × \( \frac{1}{4} \)) + \( \frac{2}{5} \) × 3 \( \frac{1}{4} \) = ?
13 \( \frac{3}{10} \)
\( \frac{130}{10} \)
\( \frac{132}{10} \)
\( \frac{13}{10} \)+ 11
