Explanation

Sabotage is a verb which means deliberately destroy something especially for political or military advantage.

Example: “power lines from South Africa were sabotaged by rebel forces”

Explanation

Let the number be x

Then,

⇒x+75% of x+25% of x3=240⇒x+75100x+25100x=240×3⇒x+34x+14x=720⇒2x=720⇒x=360

Explanation

Let  ? = X

(2567/17) × 3 = X + 180

151 × 3 = X + 180

453 = X + 180

X = 453 – 180

X = 273
