Manjul bought 5 diamond rings – R1, R2, R3, R4 and R5 – to gift to five of his female friends on their weddings. He also bought five boxes – B1, B2, B3, B4 and B5 – to keep the rings, where B1 was for R1; B2 was for R2; and so on. Then he asked his wife Nalini to pack the rings in the boxes accordingly. Nalini, miffed at his husband's decision to gift diamond rings to his female friends, decided not to follow the instructions.

The water level in a rectangular pond (with uniform depth) of dimensions 110 m × 100 m was 'h' m. An inlet pipe, in which the water flows at the rate of 30 km/h, was opened into the pond for 30 minutes. After the pipe was removed, a group of 220 people took a dip into the pond simultaneously, making the water level in the pond rise to 'H' m. If the average displacement of water by each person was 0.05 m3 and the diameter of the inlet pipe was 14 cm, then what was the absolute difference (in cm) between 'H' and 'h'?
