उत्तर : 3. "Both A & B"
व्याख्या :

Answer: C) Both A & B Explanation: Brightness of bulb depends on both voltage and current. The brightness depends on power. Since we know that  Power (P) = Voltage x Current = V I So whether you increase the current or the voltage the brightness will increase.   Example Illustration:  If you connect a long bulb and a round bulb in series, the long bulb glows but the round bulb does not. Both of them have the same current flowing through them (they are in series) but the long bulb has a greater voltage across it because it has more resistance (even though V= IR is not obeyed exactly, voltage drop does depend on the resistance). If you connect a round bulb and a long bulb in parallel, however, it is the round bulb that is brighter because now the voltage across both bulbs is the same but the current is larger through the round bulb (smaller resistance).   Hence, the brightness of a bulb depends on power i.e, both voltage and current.

उत्तर : 2. "180/11 min past 9"
व्याख्या :

Answer: B) 180/11 min past 9 Explanation: At 9 o’clock, the hour hand is at 9 and the minutes hand is at 12, i.e., the two hands are 15 min. spaces apart.So, the minute hand should gain = (30 - 15) minutes = 15 minutes55 minutes will be gained in 60 min.15 minutes spaces will be gained in ((60/55) x 15) min. = 180/11 min.The hands will be in the same straight line but not together i.e.,in 180 degrees at 180/11 min. past 9.
