72% of 25 students are good in mathematics. How many students are not good at it?
Total number of students = 25
It is given that 72% are good in mathematics. So:-
Therefore, 18 students are good at mathematics.
The number of students which are not good at mathematics = Total number of students - Number of students which are good at mathematics.
The number of students which are not good at mathematics =25 - 18 = 7 students
Your answer = 7 students
Basket contains 350 eggs. If 12% of eggs are rotten, find the number of eggs which were good and sold.
Total number of eggs=350
It is given that 12% of eggs are rotten.So:-
Therefore, 42 eggs were rotten.
The number of eggs which were good and sold = Total number of eggs - Rotten eggs
The number of eggs which were good and sold = 350 - 42 = 308 eggs
Your answer = 308 eggs
