document.write( "1.  I am thinking of a two-digit number. The tens digit is twice the ones digit. The ones digit is 4. What number am I?\r\n" );
document.write( "\r\n" );
document.write( "       I will not solve it for you / instead of you.  I sincerely believe that every person\r\n" );
document.write( "       who reads it attentively from the beginning to the end is able to solve it MOMENTARILY \r\n" );
document.write( "       if he/she does understand the meaning of the words.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "2.  How many two-digit numbers contain the digit 5 ?\r\n" );
document.write( "\r\n" );
document.write( "        Again, I will not solve it for you / instead of you.\r\n" );
document.write( "        I will help you in other way, by separating the whole problem into the series of questions:\r\n" );
document.write( "\r\n" );
document.write( "        a) how many two-digit numbers from 10 to 19 contain the digit 5 ?\r\n" );
document.write( "        b) how many two-digit numbers from 20 to 29 contain the digit 5 ?\r\n" );
document.write( "        c) how many two-digit numbers from 30 to 39 contain the digit 5 ?\r\n" );
document.write( "           . . . . . . . .\r\n" );
document.write( "        x) how many two-digit numbers from 90 to 99 contain the digit 5 ?        \r\n" );
document.write( "\r\n" );
document.write( "        The rest is on you.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "3.  How many digits are needed to write down all numbers from 1-100?\r\n" );
document.write( "\r\n" );
document.write( "        Use the same approach: subdivide the BIG question into the series of smaller questions.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "4.  the number of digits used to write all the page numbers in a book is 35. How many pages has the book?\r\n" );
document.write( "\r\n" );
document.write( "        First think about pages from 1 to 9.\r\n" );
document.write( "\r\n" );
document.write( "        Then think on pages from 10 to 19.\r\n" );
document.write( "\r\n" );

document.write( "5.  How many whole numbers from 1 to 100 contain the digit 2 exactly once?\r\n" );
document.write( "\r\n" );
document.write( "        Apply the same approach as in n.2.\r\n" );
