Question

the difference between a 2 digit number and the number obtained by interchanging the digit is 36. what is difference between the sum and the difference of the number if the ratio between the digits of its number is 1:2​

Answer 1

Answer:

8

Step-by-step explanation:

Since the number is greater than the number obtained on reversing the digits, so the ten's digit is greater than the unit's digit.

Let ten's and unit's digits be 2x and x respectively.

Then, (10 x 2x + x) - (10x + 2x) = 36

9x = 36

x = 4.

Required difference = (2x + x) - (2x - x) = 2x = 8.
