One-sixth of the trees in a garden are neem trees. Half of the trees are Ashoka trees and the remaining are eucalyptus trees. If the number of neem trees is five, how many eucalyptus trees are there in the garden ?
Answer: B
There are 10 eucalyptus trees.
Neem trees are one-sixth of the total, and there are 5 of them, so the garden has \(5 \times 6 = 30\) trees. Half, 15, are Ashoka trees. The rest are eucalyptus:
\[ 30 - 5 - 15 = 10 \]
Equivalently, eucalyptus trees are \(1 - \frac{1}{6} - \frac{1}{2} = \frac{1}{3}\) of 30. The option 15 is the number of Ashoka trees and 5 the number of neem trees.
