A Mathematics teacher gave a 20-item surprised quiz to his 25 students. All of the scores of the students were unique except for the scores of Aiza and Glaiza because both of them got the same score of 12. Their scores were in the 60th percentile. 1.How many students have scores less than 12?

2. How many students have scores greater than 12?​

total number of students is 25

AIZA AND GLAIZA came 60% of the 25 students that is 15th position

A) therefore students which came below them were= 10

B) Students who has scored greater than them were=> 15-2=13 (as they niether got less than 12 nor more than 12.)

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

the answer is c. 23/3
