Question

Write down all the even numbers from 30 to 300. How many times will the digit "6" appear?

Answer 1

Step-by-step explanation:

In the Numbers from 30 to 99 the 6 will be written 1*4 + 6*1 + 1*1*2 = 12

In the Numbers from 100 to 300 the 6 will be written 0 + 3*1*4 + 3*9*1 + 3*1*1*2 = 45

So the six will be written 12 + 45 = 57 times

Is this right? Do you have the same result?
