Two cranes are lifting 100 tons. If crane A has 40% of the load, how much weight will crane B have on its hook?

To determine how much weight crane B will have on its hook, it’s essential to first understand the total load being lifted and how the load is distributed between the two cranes.

The total load is 100 tons, which is equivalent to 200,000 pounds (since 1 ton equals 2,000 pounds). If crane A is lifting 40% of this load, we can calculate its share:

40% of 200,000 pounds is calculated as follows: 0.40 x 200,000 = 80,000 pounds.

This indicates that crane A has 80,000 pounds on its hook. To find out how much weight crane B is lifting, we subtract the weight that crane A is lifting from the total weight.

Total weight (200,000 pounds) - Weight carried by crane A (80,000 pounds) = Weight carried by crane B.

200,000 pounds - 80,000 pounds = 120,000 pounds.

Therefore, crane B is lifting 120,000 pounds.

The answer is not A, but rather the correct calculation leads to crane B carrying 120,000 pounds, which means that none of the options listed in the original question clearly correspond to the findings based on the initial
