Question

i bet u cant give the correct answer.if u solve this i will do what ever u want. but i know no one can solve this cause no one has brain.lol

A teacher wrote a large number on the board and asked the students to tell about the divisors of the number one by one.

The 1st student said, "The number is divisible by 2."
The 2nd student said, "The number is divisible by 3."
The 3rd student said, "The number is divisible by 4."
.
.
.
(and so on)
The 30th student said, "The number is divisible by 31”

The teacher then commented that exactly two students, who spoke consecutively, spoke wrongly.

Which two students spoke wrongly? Explain your answer with appropriate justification.

Answer 1

"16th and 17th" Students is the answer.

▶The secret numbers are consecutive so one is even and one is odd.

✔Also,

▶It can't be any two consecutive numbers if it is not divisible by 2 and 3.
-: For example, it also wouldn't be divisible by 6 or 8 or 9, etc, which would violate the condition.

✔Hence,

▶These two numbers cannot have multiples that are less than 31. Eliminating 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15.

✔Hence,

▶These two numbers cannot have multiples that are less than 31. Eliminating 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15.

▶When we Eliminating all of those, we get that the answer is number 16 & 17.
