Answer:
No.of students in senior secondary the previous year= 400
This year it rose by 15%
Therefore first we need to find how much is 15%
So,if we need to find this year's number of students you need to find the number of students in the present year
You need to do the following
I = P×R×T/100
So, 400×15×1/100
Do cutting method to simplify you'll get 60.
Then to find the no.of students in present year =
400+60
=460
Therefore,in the peesent year there are 460 students in senior secondary.
