Answer 1

Answer:

55

Step-by-step explanation:

Lali's rank= 27

Riya's rank= 27-7=20

Now,

for example,

there are 4 students. I am second. So I am second from front and third from back. So total number of students=

=(rank from first) + (rank from bottom) - 1

=2+3-1

=4 (proved)

Hence,

no. of students = 20+36-1

= 55
