The following table gives information of panchayat elections held in 6 villages P,Q,R,S,T and U.
| Village | Total number of votes (in hundreds) | Votes polled (in %) | Valid votes (in %) |
| P | 50 | 80 | 80 |
| Q | 60 | 75 | 80 |
| R | 100 | 65 | 65 |
| S | 80 | 60 | 70 |
| T | 60 | 80 | 90 |
| U | 40 | 90 | 60 |
Hint:
\[
1) \; \text{percentage of votes polled} = \frac{\text{Total votes polled}}{\text{Total number of votes}} \times 100
\]
\[
2) \; \text{percentage of valid votes} = \frac{\text{Total valid votes}}{\text{Total votes polled}} \times 100
\]
Find the Ratio of invalid votes of village R to that of village U?
A and B working separately can complete a piece of work in 10 and 16 days, respectively. If they work for a day alternately, with A beginning the work, in how many day(s) will the work be completed?
\( 10 \frac{1}{4} \)
\( 12 \frac{1}{4} \)
\( 1 \frac{1}{4} \)
\( \frac{1}{4} \)
If the length of the diagonal of a cube is 7\(\sqrt{3}\) cm, then the surface area of the cube is:
If â–³BPQ ≅ â–³ASR and ∠A =\( \frac{1}{3} \)∠R = ∠S, then find ∠Q. (All angles are in degrees)

500π - 350\(\sqrt{3}\) cm²
600π - 450\(\sqrt{3}\) cm²
