Question : The following table gives information on panchayat elections held in six villages P, Q, R, S, T, U.
Total no.of votes in hundred
Valid votes in %
Hint: 1) percentage of votes polled $=\frac{\text { Total votes polled }}{\text { Total number of votes }} \times 100$ 2) percentage of valid votes $=\frac{\text { Total valid votes }}{\text { Total votes polled }} \times 100$ Find the ratio of invalid votes of village R to that of village U.
Option 1: 455 : 268
Option 2: 321 : 107
Option 3: 455 : 288
Option 4: 423 : 755
Correct Answer: 455 : 288
Solution : Invalid votes = Total votes polled – Valid votes Total votes polled in village R = 65% of 10000 = $\frac{65}{100}\times10000$ = 6500 Valid votes polled in village R = 65% of 6500 = $\frac{65}{100}\times 6500$ = 4225 ⇒ Invalid votes = 6500

Question : $\triangle \mathrm{ABC}$ is a right-angle triangle at B and $\tan \mathrm{A}=\frac{3}{4}$, then $\sin A + \sin B + \sin C$ will be equal to:
Option 1: $2 \frac{4}{5}$
Option 2: $2 \frac{2}{5}$
Option 3: $3 \frac{1}{5}$
Option 4: $1 \frac{1}{5}$
Correct Answer: $2 \frac{2}{5}$
Solution : In $\triangle \mathrm{ABC}$, $\tan \mathrm{A}=\frac{3}{4}$ Let the length of sides $BC$ and $BA$ be $3k$ and $4k$. By Pythagoras theorem, $AC^2=BC^2+BA^2$ ⇒ $AC^2=3k^2+4k^2$ ⇒ $AC^2=25k^2$ ⇒ $AC=5k$ ⇒ $\sin A = \frac{BC}{AC}$ ⇒ $\sin A = \frac{3k}{5k}$ ⇒ $\sin A = \frac{3}{5}$ ⇒ $\sin
Question : Directions: In a certain code language, INNER is written as SNNWJ, and GLASS is written as UPAII. How will MODEL be written in that language?
