Question

In the ‘Primery school, each kid's roll number is a prime number. They stand in a line in ascending
order. Each kid starting from the second kid (roll number 3), tells the difference between her roll
number and the kid standing in front of her. Calculus is fast adding up all the differences as shouted
by the kids (in turn). However, Supandi already knows the answer that calculus will get, as she is the
last kid (315t) in the line with roll number 127. What is the sum that Calculus (or Supandi) get?​

Answer 1

Answer:

14

Step-by-step explanation:

the prime number that comes before 127 is 113

thus the difference between 127 and 113

the answer is 14
