Question

7. If the difference of two digit number and the number obtained by reversing the digits
is 27, find the difference between the digits of the 2-digit number​

Answer 1

Answer:

3

Step-by-step explanation:

let the units digit be y and tens digit be x

the original number will be 10x+y

so, acc to the question

10x+y-(10y+x)=27

10x+y-10y-x=27

9x-9y=27

dividing it by 9, we get

x-y=3
