conversations.value: Ten dozens of watermelons are equal to 10 x 12 = 120 watermelons.
  Yesterday, Alice sold 120 x 40/100 = 48 watermelons.
  So, there are only 120 - 48 = 72 watermelons left for today.
  Today, Alice sold 72 x 1/4 = 18 watermelons.
  Hence, 72 - 18 = 54 watermelons are left to be sold tomorrow.
