What is the difference between a two digit number and the number obtained?
Show
Complete step-by-step answer: Note: We have formed two linear equations in two variables and simplified them to find the number. A linear equation in two variables is an equation of the form \[ax + by + c = 0\], where \[a\] and \[b\]are not equal to 0. For example, \[2x - 7y = 4\] is a linear equation in two variables. What is the difference between a two digit number and the number obtained by interchanging the positions of its digits is 45?Detailed Solution
The difference between a two digit number and the number obtained by interchanging the position of its digit is 45. Calculation: Let Two digit number be 10a + b. The difference between two digit number is 5.
What is the difference between two digits in a two digit number?The number itself is 1 more than 5 times the sum of its digits. If the units digit is greater than the tens digit, what is the number? The difference between the digits of a two-digit number is 1. The number itself is 1 more than 5 times the sum of its digits.
Are certain 2Detailed Solution
Such numbers will be 41, 52, 63, 74, 85 and 96. There are six such numbers.
What is special about the difference of a two digit number and the number got on reversing the digits?Hence the difference of a two digit number and the number obtained by reversing the digit is always divisible by 9.
