Tatuya scored twice as much as Ivanna, and Ivanna scored 3/5 times as many marks as Dorothy. If Dorothy scored 90 marks, calculate the average marks scored by the three.

conversations.value: Since Dorothy scored 90 marks, and Ivanna scored 3/5 times as many marks, Ivanna scored 3/5*90 = 54 marks.
  Together, Dorothy and Ivanna scored a total of 54+90 = 144 marks.
  If Tayuta scored twice as many marks as Ivanna, she scored 2*54 = 108 marks.
  The total marks the three scored altogether is 108+144 = 252 marks.
  The average marks for the three are 252/3 = 84 marks.
