The weight limit that a truck can transport corresponds to 50 bags of sand or 400 bricks. If this truck is already carrying 32 bags of sand, how many bricks, at most, can it still carry?
(a) 132
(b) 144
(c) 146
(d) 148
(e) 152
The correct option is (b).

Since the weight of a bag of sand is equal to that of eight bricks and there are already 32 bags of sand in the truck, it can still carry 18 more bags of sand, which is equivalent to $18 \times 8=144$ bricks.
