Answer 1

• 16 students like to study science.

Step-by-step explanation:

Given:

• Total number of students in a class = 40
• 2/5 of the total students like to study mathematics
• 1/5 of the total number of students like to study English.
• The remaining students like to study science.

Students who like mathematics = 2/5 of the total students

= 2/5 * 40

= 2 * 8

= 16

∴ 16 students like mathematics.

And,

Students who like English = 1/5 of the total students

= 1/5 * 40

= 8

∴ 8 students like English.

Now,

The remaining students who like science are

= Total number of students - (Sum of the students who like Mathematics and English)

= 40 - (16 + 8)

= 40 - 24

= 16

• 16 number of students like science.

Answer 2

Answer:

✡ Solution ✡

✏ Total no of students = 40

➡ No of students liked English,

=> $\dfrac{1}{5}$ of 40

=> $\dfrac{1}{5}$ × 40

=> 8 students

➡ No of students liked Math,

=> $\dfrac{2}{5}$ of 40

=> $\dfrac{2}{5}$ × 40

=> 16 students

➡ No of students liked science,

=> 16 + 8 + x = 40

=> 24 + x = 40

=> x = 40 - 24

=> x = 16

Hence, 16 students liked Science.
