# Different Approach

Airport taxi

Would it have been wrong to take a different approach with calculating the revenues?

The approach I took was, I tried to calculate the total daily revenue through calculating the revenues from the night and day shift separately.

Firstly,

no. passengers per day = (airport passengers) * (percentage of passengers using taxi)/ (days in a year)

= 84M*20%/350

= 48,000 passengers

That means,

daytime shift = (total taxis used in day) * dayfare

= (no. of passengers per day * % of day passengers)/passengers/taxi * dayfare

assuming on average a taxi is shared between 2 passengers

= (48,000* 50%)/2 * 70

= 840,000

Night shift = (total taxis used at night) * dayfare

= (no. of passengers per day * % of night passengers)/passengers/taxi * dayfare

assuming on average a taxi is shared between 2 passengers

= (48,000* 50%)/2 * 80

= 960,000

Total Daily Revenues = 840,000+960,000 =1.8M

Hi,
I confirm it is correct and maybe more intuitive. However, the proposed one is preferable in terms of speed.

Hello!

Altough it works, simplicity is also something to be valued (in terms of shortest time to calculations, less options to fall in pitfalls, etc.)

Hence, unless you don´t understand the other one, I would go with it.

Hope it helps! Cheers,

Hello,

Your approach sounds fine but I think it's more complex than the one proposed in the solution, I would keep the solution proposed.
