Question

About 2,50,000 people travelled using public transport in a city in 2017. If the number of people travelling by public transport has been increasing at 2% per year, how many people travelled by public transport in 2020?​

Answer 1

Answer:

250000×2÷100= 5000 increasing per year

so,

2020-2017 = 3 years

= 5000 × 3 =15000

= 250000+15000 = 265000

265000 people travelled by public transport in 2020

Answer 2

Given: About 2,50,000 people travelled using public transport in a city in 2017. If the number of people travelling by public transport has been increasing at 2% per year.

To find: How many people travelled by public transport in 2020.

Solution:

According to the question, the number of people using public transport in a city increases by 2% every year and 2,50,000 people travelled using public transport in the year 2017. So, the increase can be calculated as follows.

$increase = \frac{2}{100} * 250000$

              $=5000$

By the year 2020, the number of people using public transport would have increased three times by 2%. Hence, the total increase is

$5000 * 3 = 15000$

Now, the total number of people that travelled by public transport in 2020 is

$250000 + 15000 = 265000$

Therefore, 265000 people travelled by public transport in 2020.
