Given : 8% Of the student at a school are in year 8, and 16 % of the students are In year 9,
the school has 126 year 8 students,
To Find : the number of year 9 students
Solution:
Let say Total Students = 100P
8% Of the student at a school are in year 8
=> ( 8/100)100P = 8P
school has 126 year 8 students,
=> 8P = 126
=> P = 63/4
=> 100P =6300/4
Hence total Students = 6300/4
16 % of the students are In year 9
number of year 9 students = (16/100)6300/4 =4 * 63 = 252
252 Students are in year 9
