conversations.value: A tree had 1000 leaves before the onset of the dry season, when it sheds all its leaves. In the first week of the dry season, the tree shed 2/5 of the leaves. In the second week, it shed 40% of the remaining leaves.  In the third week, the tree shed 3/4 times as many leaves as it shed on the second week. Calculate the number of leaves the tree hadn't shed by the third week.
  Can you solve this problem?

conversations.value: In the first week, the tree shed 2/5*1000 = 400 leaves.
  The number of leaves remaining on the tree at the end of the first week is 1000-400 = 600
  In the second week, the tree shed 40/100*600 = 240 leaves.
  The number of leaves remaining on the tree is 600-240 = 360
  The third week the tree shed 3/4 of its leaves, a total of 3/4*360 = 270 leaves.
  The number of leaves remaining on the tree is 360-270 = 90 leaves.
