Correct Answer: Option B
Explanation:
125x = 20
1xX2 + 2xX1 + 5xX0 = 20X2 + 2X + 5 = 20X2 + 2X - 15 = 0
(X + 5)( X - 3) = 0X + 5 implies X = -5X - 3 implies X = 3
But X cannot be negative
∴X = 3
125x = 20
1xX2 + 2xX1 + 5xX0 = 20X2 + 2X + 5 = 20X2 + 2X - 15 = 0
(X + 5)( X - 3) = 0X + 5 implies X = -5X - 3 implies X = 3
But X cannot be negative
∴X = 3
