I gona doubt this ans
The value of a-b is 2.
Step-by-step explanation:
Consider the provided information.
A number is divisible by a number, is it always divisible by factors of that number.
Since 10 is a factor of 80, 23583ab is divisible by 10. It means last digit, should be 0.
Rewriting 23583ab as 23583a0. Since 8 is a factor of 80, 23583a0 is divisible by 8. It means last three digits 3a0 is divisible by 8.
There are 2 choices for a, either we can choose 0 or 2
Hence, the value of a can be 0 or 2 .
if x=0, number is 2358300. Which is not divisible by 80 .
if x=2, number is 2358320. Which is divisible by 80 .
Therefore, the number is 2358320 with a=2 and y=0.
a-b = 2-0 = 2
The value of a-b is 2.
