Best answer
Correct Answer - Option 2 : 48

Given:

The number of girls who donated blood in department A = 40%

Total number of girls who donated blood in department A = 25% of the department

Calculations:

 Department percentage of girls percentage of blood donating girls* number of blood donating Boys* percentage of blood donating boys number of blood donating girls A 25% 40% 48 60% 32 B 40% 50% 75 50% 75 C 30% 70% 39 30% 91

25% of girls = 32

100% of department = 32 × 100/25 = 128

Blood donated students in department A = 32 + 48 = 80

The number of boys who did not participate in the blood donation camp = total number of students - number of students who donated blood

⇒ 128 – 80 = 48

∴  The number of boys in the department 'A' who did not participate in the blood donation camp is 48
