Solution

## The correct option is B x≤−16Given algebraic inequality, −4x10≥325 We know that on multiplying a positive number on both sides of an algebraic inequality, the inequality sign remains same. On multiplying both the sides of the inequality by 10, we get, −4x10×10≥325×10 ⇒−4x≥64 We know that on dividing a negative number on both sides of an algebraic inequality, the inequality sign gets flipped. On dividing both the sides of the inequality(−4x≥64) by −4, we get, −4x−4≤64−4⇒x≤−16
