# Find The Value of abc? If

If a, b and c are non-zero, a + 1/b = 1 and b + 1/c = 1, then, the value of abc is

- -3
- 1
- -1
- 3

**Answer: (3) -1
Explanation:-**

a + 1/b = 1

ab + 1 = b ………………….. (1)

And, b + 1/c = 1

b = 1 -1/c …………………………… (2)

On equating equation (1) & (2),

ab + 1 = 1 – 1/c

ab = -1/c

abc = -1

Hence, the answer is (3) – 1.
