Q3) 72% of 25 students are good at mathematics. How many are not good at mathematics?

Answer:

Solution:

Total number of students = 25

Number of good students in mathematics = 72% of 25 = \frac{72}{100}\times25=18

Number of students not good in mathematics = 25 – 18 = 7

Hence percentage of students not good in mathematics = \frac{7}{25}\times100=28\%
