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

a +	1	= 1 ⇒ ab + 1 = b
	b

⇒ ab = b – 1 .....(i)
Again,

b +	1	= 1
	c

1	= 1 − b ⇒ c =	1	.....(ii)
c		b − c

On multiplying (i) & (ii)

abc =	b − 1	= − 1
	1 − b

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