The volume of the stone is equal to the volume of the water increased in the measuring cylinder. The volume of the stone is calculated from the formula Volume =Mass/Density. In this case, the Mass = 12 g and Density = 3g cm^3 Volume = 12/3 = 4 cm^3 The actual volume of liquid in the measuring cylinder is 20cm^3 . So, the increase in volume will show a new reading of 20cm3+4cm3=24cm^3 hence...answer is (B)

When the key K is closed, an electric current starts flowing in the circuit . The current which passes through bulb P gets divided  in bulbs Q and R. For the identical bulbs , the brightness will depend upon the current flowing through the bulbs,So P will glow brighter than Q and R .

the current starts flowing from positive end to negative end in a closed circuit and in this case , current first gets divided and passes through Q and R and then the current again gets add up and passes through p. so due to the greater flow of current through P it is more brighter.
