Answer 4

There's the weight of the truck, and the weight of the papers.

The weight of the truck doesn't change ever. The weight of the papers depends on how full the truck is.

Let P be the weight of papers if the truck is full, tyhen:


T + (1/2)P = 1762kg.
T + (1/4)P = 1426kg.

(1/4)P= 1762 - 1426

From that, find P.

Now you know P, find T.

And the answer will be P + T.
