Explanation

Let the number be x Then, x+17=60x⇒x2+17x−60=0⇒(x+20)(x−3)=0⇒x=3

Explanation

144/8 = 18 people.

Thus you would need twelve additional people.

Explanation

Total number of votes = 7500

Given that 20% of Percentage votes were invalid

 => Valid votes = 80%

 Total valid votes = 7500*(80/100)

1st candidate got 55% of the total valid votes.

Hence the 2nd candidate should have got 45% of the total valid votes

=> Valid votes that 2nd candidate got = total valid votes x (45/100)

7500*(80/100)*(45/100) = 2700

Explanation

By Using formula 

2n+1=23

⇒    n=11

Explanation

Let third number is x. Then first no.20%ofx=20x100 Second number=50%ofx=50x100 Percent of first no of second no,=20x10050x100×100=2×10020= 40%
