Answer 1

Answer:

$\huge\underline\bold {Answer:}$

Let the full number passengers be x.

Number of passengers at the first station

$= (x - \frac{1}{3x} ) + 96 = \frac{2x}{3} + 96$

Number of passengers at the second station =

$\frac{1}{2} ( \frac{2x}{3} + 96) + 12 \\ = \frac{x}{3} + 48 + 12 = \frac{x}{3} + 60$

Given,

$\frac{x}{3} + 60 = 240 \\ = > \frac{x}{3} = 240 - 60 = 180$

$= > x = 180 \times 3 = 540.$

Therefore, the number of passengers in the beginning was 540.
