What will be the value of a/b ? Given that a and b are positive integers

(2) a – b = 1
Given information= a and b are positive integers
Question asked=a/b?
(1) a^2 – b^2 = 169
169 has 3 factors 1, 13, 169
(a+b) (a-b)= 13 X 13
Since 169 is +ve number and a and b both are positive (a-b) will be +ve, which means a>b
if a>b and both a and b are positive, then (a+b) and (a-b) both will have different values and those values can be 169 and 1 respectively
a+b= 169
a-b= 1
We can find the value of both a and b and a/b
Statement 1 is sufficient
2) a – b = 1
a and b can have multiple values (3-2 or 5-4 or 9-8 and so on)
Not sufficient
A is the answer
