Question

A school had 1200 learners in 2020 in 2021 the school has 1380 what is the percentage increase from 2020 to 2021

Answer 1

Answer:

15%

Step-by-step explanation:

Learners in 2020: 1200

Learners in 2021:  1380

To calculate the increase in percentage, we can use 2 methods (as far as I know).

For this question, i believe the following method is more suitable.

Difference in learners = 1380-1200

                                    =  180

1% of 1200 = 1200/100

                  = 12

∴Percentage increase = 180/12

                                     = 15%
