Answer:
Option 4
Explanation:
In integer division or multiplication,
- If both numbers are negative or positive, the answer will be positive.
- If one number is negative and other number is positive, the answer will be negative.
1) If a < 0 and b < 0 means a and b are both negative numbers.
Then a/b will be positive. But it is given that a/b < 0. So, it is wrong.
2) If a< 0 and b > 0 means a is negative & b is positive. So, a/b will be negative. But it is given a/b is positive. So, it is wrong.
3) a and b are positive (as a >0 and as b > 0), then a/b > 0 (a\b will be positive). So, it is wrong.
4) a is positive (as a>0) & b is negative (as b < 0), then a/b will be negative So, this is correct.
