If 4 trains with 12 wagons each can carry 840 tons, then each train with 12 wagons can carry 840/4 = 210 tons. Therefore, each wagon can carry 210/12 = 17.5 tons. Since each train with 18 wagons can carry 18 x 17.5 = 315 tons, then 6 trains with 18 wagons each can carry 6 x 315 = 1890 tons of coal. **

A carry bit, also known as a carry flag, is a single bit in a computer processor's status register that indicates whether an arithmetic operation has resulted in a carry out of the most significant bit.

The carry bit is important for multi-byte addition and subtraction operations, as it allows the processor to handle overflow and underflow conditions. **
