Question : In an election between P and Q, P gets 40% of the total votes and thus loses by 10 votes. The total number of votes is:
Option 1: 80
Option 2: 50
Option 3: 90
Option 4: 70
Correct Answer: 50
Solution : Let $x$ be the total number of votes. Number of votes P got = 40% of $x$ Number of votes Q got = 60% of $x$ Margin = 10 ⇒ $0.6x - 0.4x = 10$ ⇒ $0.2 x = 10$ ⇒ $x = \frac{10}{0.2}$ ⇒
Question : If $x+y+z=17, x y z=171$ and $x y+y z+z x=111$, then the value of $\sqrt[3]{\left(x^3+y^3+z^3+x y z\right)}$ is:
Option 1: –64
Option 2: 4
Option 3: 0
Option 4: –4
Correct Answer: –4
Solution : Given: $x + y + z = 17,xy + yz + zx = 111$ and $xyz = 171$ $(x + y + z)^2 = x^2 + y^2 + z^2 + 2(xy + yz + zx)$ $⇒17^2 = x^2 + y^2 + z^2 + 2 ×
