For integers a, b and c, what would be the minimum and maximum values respectively of a + b + c if loga + logb + logc = 0
 –3 and 3
 –1 and 1
 –1 and 3
 1 and 3
Correct Option : A
log a + log b + log c = 0
It is possible only,
when a, b and c all are equal to 1.
∴ a, b, c may be ±1, ±1, ±1 respectively.
Now for minimum value of all three will be negative.
∴ minimum value =  3
and maximum value of all three will be positive.
∴ maximum value = +3
