nikitadnepr [17]
U={1,2,3,4,5,6,7,8}; A={1,3,5,7} = B; C={5,8}; D={2,5,8}
All are subset of U
A is a subset of B & vice versa
C is a subset of D, but neither C nor D are subset of A or B
K=29 is the correct answer
Answer:
24
Step-by-step explanation:
75% of x = 18
75/100 * x = 18 (x = total number of students)
solving
x = 24
total number of students = 24
Checking:
75/100 * 24 = 18
