Answer:
Yes she is right
Step-by-step explanation:
Given that Ayesha has a theory about two digits numbers that have a larger tens digit then ones digit.she says that reversing the digits and subtracting the reversed number from the original number will always generate a number that is multiple of 9.
The reason is as follows: Let x be in 10th digit and y be in unit digit.
x>y
10x+y will be the place value.
If reversed we have 10y+x would be the value of the number
Difference would be
Hence this has to be a multiple of 9.
thx if anyone helps
