Answer Posted / jimesh gajera
3/5 of 4 year is 2.4 year.
tree A has growth rate 2.4 and B has a 4 year.
now, both tree has a 8 feet height means tree A is increase
in 2.4 year is equal to the tree B is increase in 4 year.
next 2 year...
for tree B if it is increase 8 feet in 4 year so in next 2
year 8/4=2 feet in 1 year. means tree B increase 4
feet.total height is 12 feet.
and tree A if it is increase 8 feet in 2.4 year means
approximately in 2 year so it is increase 8 feet another. so
total height is more than 16 feet.
so, height of the smaller tree after 2 year is 12 feet.
