Can you give an example of a number which is divisible by 10 but not by 2 and 5? Why?
what is the answer

Answer 1

Answer:

No such number exists which is divisible by 10 but not by 2 and 5 because

Divisibility rule of implies that Every even number is divisible by 2 and Divisibility rule of 5 says each number which ends with 0 and 5 are divisible by 5

Divisibility rule of 10 says that each number ending with 0 is divisible by 10

No such number exists which would satisfy this condition which is given in the question
