In a four-digit number, the sum of the first two digits is equal to the sum of the last two digits. If the sum of the digits is 30 and the sum of the digits in units place and thousands place is twice its digit in hundreds place, then which of the following cannot be the units digit?

For a 4-digit number, the sum of its digits in the thousands, hundreds and tens places is 14, the sum of its digits in the hundreds, tens, and units places is 15, and the tens place digit is 4 more than the units place digit. Then the highest possible 4-digit number satisfying the above conditions is

A number consists of two digits and the digit in the ten’s place exceeds that in the unit’s place by 5. if 5 times the sum of the digits be added from the numbers, the digits of the number are reversed. Then the sum of digits of the number is?

I am a 4-digit number.The digit in the thousands place is 4.The digit in the hundreds place is half the digit in the thousands place.The digit in the tens place is thrice the digit in the hundreds place.The 4 digits add up to 19.What number am I?
