QUESTION

# The number of passengers on a train increases from 63 to 77. Calculate the percentage increase in passengers.

Thus, the increase in the number of passengers $=77-63=14$.
Thus, the percentage increase in the number of passengers $=\dfrac{14}{63}\times 100$.
Simplifying the above expression by cancelling out the common terms from numerator and denominator, the percentage increase in the number of passengers $=\dfrac{2}{9}\times 100=22.23%$.
Hence, the percentage increase in the number of passengers in a train is $22.23%$.
