Question : In an election between two candidates, 85% of the voters cast their votes, out of which 4% of the votes were declared invalid. A candidate got 6,936 votes which was 85% of the valid votes. Find the total number of voters enrolled in that election.
Option 1: 10,500
Option 2: 10,800
Option 3: 10,000
Option 4: 10,700
Correct Answer: 10,000
Solution : Let the number of voters enrolled be $x$. Given votes = 85% of $x$ = $\frac{17x}{20}$ Valid votes = 100 – 4 = 96% of $\frac{17x}{20}$ = $\frac{24}{25}×\frac{17x}{20}=\frac{102x}{125}$ The winner gets 85% of valid votes. So, 85% of $\frac{102x}{125}=6936$ $⇒\frac{17}{20}×\frac{102x}{125}=6936$ $\therefore x =10000$ Hence, the
Question : Simplify the following. $9 \times 2 \div 3\ \text{of} \ 24 - 3 \div 2 \times (6 - 7) \times 2 + 3 \div 3\ \text{of}\ 5$
Option 2: $\frac{9}{20}$
Option 3: 4
Option 4: $\frac{69}{20}$
Correct Answer: $\frac{69}{20}$
Solution : $9 \times 2 \div 3\ \text{of} \ 24- 3 \div 2 \times (6 - 7) \times 2 + 3 \div 3\ \text{of}\ 5$ $=9 \times 2 \div 3\ \text{of} \ 24 - 3 \div 2 \times- 1 \times 2 + 3 \div 3\ \text{of}\ 5$
Question : If $ax^{2}+bx+c=a(x-p)^{2}$, then the relation among $a, b ,$ and $c$ would be:
Option 1: $abc=1$
Option 2: $b^{2}=ac$
Option 3: $b^{2}=4ac$
Option 4: $2b=a+c$
Correct Answer: $b^{2}=4ac$
Solution : $ax^{2}+bx+c=a(x-p)^{2}$ ⇒ $ax^{2}+bx+c=a(x^{2}-2px+p^{2})$ ⇒ $ax^{2}+bx+c=ax^{2}-2apx+ap^{2}$ Comparing the corresponding coefficients, we get, $ b = -2ap$-----------(i) $ c = ap^2$---------------(ii) Squaring equation (i), we have, ⇒ $ b^2 = 4a^2p^2 $ ⇒ $ p^2 = \frac{b^2}{4a^2}$-------------(iii) Substituting (iii) in (ii), we get, ⇒ $ c =
