Answer

20\text{20}

Step-by-step solution

3 steps
  1. Locate the range "120-139" on the x-axis (Number of passengers).

  2. Find the bar corresponding to this range.

  3. Read the height of this bar on the y-axis (Number of trains).

    The top of the bar aligns with the value 20 on the y-axis.

    Therefore, 20 trains had between 120 and 139 passengers.

    The number of trains is 20\text{20}.
