Question

There are 400 students in the school during session 2019-20. If students are increased

by 20% during session 2020-21. Find the total number of students.​

Answer 1

Answer:

session 2019-2020 400 students in the school ,

session 2020-2021 students are increased by 20%,

find the total number of students.

400/100×20= 4×20=80

therefore 20% is 80

therefore 400+80=480

session 2020-2021 480 students in the school ,

400+480=880

therefore the total number of students is 880 students
