From II: Volume = πr 2 h So by successive formula, the increase in volume can be found First: rate 2 So 25 + 25 + (25)(25)/100 = 56.25% Next: 56.25 + 20 + (56.25) × (20)/100 = 87.5% (final increase in volume) From I and III: volume of given shape (cylinder, cube, cone) = 20 litre (initial volume). And ice cube of height 20 cm is dip into it. So after finding new volume or increase in volume after the ice cube is dipped, % increase in volume can be found.
