Answer: 140 scoops.
Step-by-step explanation:
We know that she sold 3/4 of the chocolate ice cream and 1/2 of the vanilla ice cream. She originally had 20 scoops of chocolate and 30 of vanilla left.
so those 20 scoops of chocolate are 1/4 of the total amount that she had before, then the total amount is equal to 4 times 20 scoops = 80 scoops of chocolate.
We also know that 30 scoops of vanilla are one half of the initial number, so the initial number must be equal to two times 30 scoops = 60 scoops.
Now, adding those numbers we have 60 + 80 = 140 scoops in total at the beginning of the day.

Using percentage, the numbers of juniors will allowed to attend an event is 50.
Percentage is "fraction or ratio, in which value of whole is 100".
According to the question,
The principal approved the event for 200 students. Number of juniors will be 25% of number of seniors.
Suppose 100% of student is 200 and then 25% of student will be
100% = 200
25% = x
100x = (200) (25) [cross multiplication]
x = 50.
Hence, the principal allowed number of student to attend an event is 50.
