How many times does the digit 1 occur in ten place in the numbers from 1 to 1000?
there are no 3 digit tis two digit! :) * * * * * 90 of them.
There are 90 of them.
in two digit number meaning a number with place value 10s and 100s.... in base ten the numbers are 0-9 this means any number appears at maximum 9 times in each place value and we have been given two place values hence it's 9*2=18 times on the positive side and 18 times on the negative side mbaruk sila

How many times does the digit 1 occur in ten place in the numbers from 1 to 1000?
There are 100 in the 400s. In the 100s, 200s, and 300s, the ones place or the tens place could be 4. There are 10 numbers with a 4 in the ones place in each 100. There are 10 numbers with a 4 in the tens place in each 100. There is one overlap where there is a 4 in both the tens and the ones place. So, there are 19 numbers with a 4 as a digit in the each 100. Therefore, there are (19 x 3) + 100 = 157 numbers with a 4 as one of the digits. Here are the numbers in the 100s with a 4 in the ones place: 104 114 124 134 144 154 164 174 184 194 Here are the numbers in the 100s with a 4 in the tens place: 140 141 142 143 144 145 146 147 148 149 These lists have 20 numbers, but 144 is duplicated, so there are 19 numbers with 4 as a digit. The same will apply to the 200s and 300s. There will be a 4 in every number in the 400s, since the hundreds digit will always be a 4.
