40% of the boys is same as half of the girls, and there are 20 girls.
So, 40% of boys = 20/2 = 10
Therefore, 100% of boys = (10/40%) × 100% = 25
Therefore, total number of boys = 25
Thus, total number of students = 25 + 20 = 45
Hence, option (b) is correct.
So, 40% of boys = 20/2 = 10
Therefore, 100% of boys = (10/40%) × 100% = 25
Therefore, total number of boys = 25
Thus, total number of students = 25 + 20 = 45
Hence, option (b) is correct.

Given Information:
- 40% of boys = 1/2 of girls
- Total number of girls = 20
Calculating the Number of Boys:
- Let the total number of boys be B.
- According to the given information, 40% of boys is the same as half of the girls.
- Therefore, 0.4B = 0.5 * 20
- 0.4B = 10
- B = 10 / 0.4
- B = 25
Calculating the Total Number of Students:
- Total number of girls = 20
- Total number of boys = 25
- Total number of students = 20 (girls) + 25 (boys) = 45
Therefore, the total number of students in the class is 45, which corresponds to option B.
