    If you write 1 to 100 counting, then how many times do you write 3?

    A) 21                          

    B) 20          

    C) 18                          

    D) 11

    Correct Answer: B

    Solution :

    Clearly from 1 to 100, there are ten numbers with 3 as the unit's digit \[-\text{ }3,\text{ }13,\text{ }23\text{ }33,\text{ }43,\text{ }53,\text{ }63,73,\text{ }83,\text{ }93\]and ten number with 3 as tens digit \[-\text{ }30,\text{ }31,\text{ }32,\text{ }33,34,35,36,37,38,39.\] So, required number \[=10+10=20.\]
