Add three numbers after 2007 to form a seven digit number, so that it can be divided by 2, 3, 5 and 11 respectively. What is the minimum number of seven digits?

Add three numbers after 2007 to form a seven digit number, so that it can be divided by 2, 3, 5 and 11 respectively. What is the minimum number of seven digits?

2×3×5×11=330
Because 6082 × 330 = 2007060; it can also be divided into 2, 3, 5, 11
So: the minimum number of seven digits is 2007060

The sum of the number in two digit ten and the number in one digit is 11. If the number in ten digit and the number in one digit are exchanged, the new number will be 63 larger than the original number?

x+y=11
10x+y-10y-x=63
x=9
y=2
The original number is 92

For a two digit number, the sum of the number on the tenth digit and the number on the single digit is 11. If the number on the tenth digit and the number on the single digit are exchanged, the new number will be 63 larger than the original number, and the original two digits will be obtained

The original solution to this question is: x = 11-9, which means the original number is 11 + (X-10)
