An observer can see through a small hole on the side of a jar (radius 15 cm) at a point at height of
15 cm from the bottom (see figure). The hole is at a height of 45 cm. When the jar is filled with a
liquid up to a height of 30 cm the same observer can see the edge at the bottom of the jar. If the
refractive index of the liquid is N/100, where N is an integer, the value of N is _____.
