Two types of boxes are to be placed in a truck having capacity of tons. When boxes of type and boxes of type are loaded in the truck, it weighs tons. But when boxes of type are loaded in the truck, it can still accommodate boxes of type , so that it is fully loaded. Find the weight of each type of box.
Solution: 
Let, weight of box A be x and B be y. 
Now, 150x + 100y = 10×1000 ----(1) 
And 260x + 40y = 10× 1000  ---(2) 
 Now , (2) × 10 - (1)
      = (2500-150)x =10⁴× 9 
      38.29 kg
      And y = 42.46 kg
