I would draw boxes for this. 
We don't know how many pounds Maria picked, so draw only 1 box:

Andre picks 3 times as many as Maria, so 1 * 3 is :
[] [] []
Jane picks 2 times as many as Andre, so 3 * 2 is:
[] [] [] [] [] []
Count all the boxes. You'll get 10 boxes. Now, divide the total number of pounds (840) by the 10 boxes. You should get 84. Multiply 84 by 3, because Andre Andre has 3 boxes in our diagram. You'll get 252 pounds. That is the final answer.
