Question : In an election between two candidates, a candidate who gets 64% of the votes polled is elected by a majority of 252 votes. What is the total number of votes polled?
Option 1: 950
Option 2: 900
Option 3: 850
Option 4: 800

Question : What is the value of $\frac{X}{Y}$ if $\frac{X-5 Y}{X+5 Y}=\frac{7}{13}$
Option 1: $\frac{23}{7}$
Option 2: $\frac{24}{9}$
Option 3: $\frac{50}{3}$
Option 4: $\frac{100}{7}$
Correct Answer: $\frac{50}{3}$
Solution : Given: $\frac{X-5 Y}{X+5Y}=\frac{7}{13}$ ⇒ $13X-65Y=7X+35Y$ ⇒ $6X=100Y$ $\therefore \frac{X}{Y}=\frac{50}{3}$ Hence, the correct answer is $\frac{50}{3}$.
