Answer:
Step-by-step explanation:
p + n + d + q = 25
Put everything into quarters.
p and q are equally likely to be drawn
q + n + d + q = 25
There are 3 times as many nickels as quarters
n = 3q
q + 3q + d + q = 25
There is 25% more dimes than quarters.
d = 1.25 q
q + 3q + 1.25q + q = 25
6.25 q = 25
q = 25/6,25
=====================
q = 4
p = 4
d = 1.25 * 4 = 5
n = 12

Answer:
25% of students attend classes in the evening.
Step-by-step explanation:
The proportion of evening students is the number of evening students divided by the total number of students.
The percentage is the proportion multiplied by 100.
We have that:
In total, there are 15000 students.
3750 are evening students
3750/15000 = 0.25
0.25*100 = 25%
25% of students attend classes in the evening.
