Question

40% of 50 students of a class are good at Science. Number of students are not good at Science ?​

Answer 1

Answer:

Number of students not good at Science = 30

Step-by-step explanation:

Total number of students = 50

40% of 50 = (40/100) x 50

= 4 x 5

= 20

20 students are good at Science.

Number of students not good at Science = (Total students - Students good at Science)

= 50 - 20

= 30
