Question
A vasculum has 300 leaves. 15% of these belong to Mustard, 20% calotropin, 10% to guava, 15% to Sunflower & the remaining to Alstonia. If 6 leaves are present at each node of Alstonia, what is the total number of nodes seen in the various twigs present in the vasculum?

Solution
The correct option is D 155
Answer is option D i.e."155"
As per information provided, total leaves =300. A single leaf arises at each node in Mustard (15%) and sunflower (15%) i.e. alternate phyllotaxy hence nodes for them are 45 and 45 nodes respectively.
A pair of leaves arise at each node in Calotropis (20%) and guava (10%) plants i.e. 30 and 15 nodes respectively.
Alstonia (40%) has whorled phyllotaxy i.e. two leaves arises at a node and form a whorl i.e. 20 nodes.
Adding all the node numbers from above, the total nodes are 155
