Let me see how clever everyone is…

Solve the riddle :

## Write numbers from 1 to 100…. how many 9s do you see?

Think properly and then answer

Check your answer:-

one 9 in every 10s (like 9, 19, 29, etc) => 10

extra 10 9s in 90 – 99 => 10

thus total 20

extra 10 9s in 90 – 99 => 10

thus total 20
