There is a three digit number. The number on the tenth digit is 23 times that on the tenth digit. The number on the tenth digit is 2 times more than that on the tenth digit. The number on the tenth digit is 2 times that on the hundred digit______ ．
The number of tens is 2 △ 2 (3-2) × 2 = 4, the number of ones is 4 + 2 = 6, and the number of hundreds is 6 △ 2 = 3, so the three digit number is 346
