(b) 21333​

Answer 1

Answer:

DEAR MATE,

Divisibility rule of 5 : The last digit of number should end with 5 or 0.

Divisibility rule of 10: The last digit of number should end with 0.

In the given question ,

( a ) 48980 - It is divisible by both 5 and 10 because the last digits end with 0.

( b ) 21333 - It is not divisible by both 5 and 10 because the last digits do not        

                   end with 5 or 0.
