Ten persons can cut 8 trees in 14 days. In how many days can 6 persons cut 10 trees ?
Answer & explanation
Correct answer: option 4
\(\frac{ M1× D1}{W1}\) = \(\frac{M2× D2}{W2}\)
\(\frac{ 10× 14}{8}\) = \(\frac{6× D2}{10}\)
\(\frac{ 10× 7}{4}\) = \(\frac{3× D2}{5}\)
D2 = 29.2
The correct answer is option (4) : 29.2
