What is the sum of the digits of a two-digit number?
The sum of the digits of a two digit number is 8 and the difference between the number and that formed by reversing the digits is 18 . Find the number. The sum of the digits of a two digit number is 8 and the difference between the number and that formed by reversing the digits is 18.
What is the sum of the numbers formed by reversing 18?
If you want to solve it without using algebra, consider the possibilities: 80, 71, 62, 53 and 44 (so that the sum of the digits is 8). The numbers formed by reversing the digits are 8, 17, 26, 35 and 44. The only pair that differs by 18 is (35, 53).
What is the sum of a two-digit number in reverse order?
The sum of a two-digit number and the number formed by reversing the order of digits is 66. If the two digits differ by 2, find the number. How many such numbers are there? – Maths Q&A The sum of a two-digit number and the number formed by reversing the order of digits is 66. If the two digits differ by 2, find the number.
What is the difference of the digits of a 3 digit number?
∴ Difference of the digits of the number is 5. 9. In a 3-digit number, unit’s digit, ten’s digit and hundred’s digit are in the ratio 1 : 2 : 3. If the difference of original number and the number obtained by reversing the digits is 594, find the number. 10.
The digits of a two-digit number differ by 3. If the digits are interchanged and the resulting number is added to the original number, the sum is 143. What is the original number? Number is 58 or 85. As te digits of two digit number differ by 3, there are two possibilities.
How do the digits of two digit numbers differ by 3?
As te digits of two digit number differ by 3, there are two possibilities. One the unit digit be x and tens digit be x + 3, and two that tens digit is x and unit digit is x + 3. In first case, if unit digit be x and tens digit is x + 3, then number is 10(x + 3) + x = 11x +30 and on interchanging numbers, it will become 10x + x + 3 = 11x + 3.
What is the difference between the two digits of 143?
[SOLVED] The digits of a two – digit number differ by 3 . If the digits are interchanged and the resulting number is added to the original number, we get 143 . What can be the original number? The digits of a two-digit number differ by 3. If the digits are interchanged and the resulting number is added to the original number, we get 143.
What is the sum of the digit in the tens place?
The digit in the tens place differs from x by 3. Let us take it as x + 3. So the two-digit number is 10 (x + 3) + x = 10x + 30 + x = 11x + 30. With interchange of digits, the resulting two-digit number will be 10x + (x + 3) = 11x + 3 It is given that the sum is 121. The units digit is 4 and therefore the tens digit is 4 + 3 = 7.
