Parvati Patil enters a forbidden chamber at the Hogwarts School of witchcraft and wizardry. She is cursed and petrified and placed on a stone S which moves 25 steps per year. There are two more stone blocks – A and B and they also move. But the movement of block S does not obstruct the movement of blocks A or B. A moves 5 steps towards B in a year and 4.5 steps in the direction away from B in the next year. B moves 9 steps in the direction away from A in a year and 11 steps towards A in the next year. However, when A moves towards B, B moves away from A and vice versa. The initial distance between A and B is 1000 steps. Parvati’s curse will be lifted when blocks A and B bang each other. What is the sum of the distances travelled by-Parvati’s block, block A and block B when the curse is lifted?
