The pressure at the depth h1 = P1 = 3 * 10⁵ N/m²

pressure at the depth h2 = P2 = 5 * 10⁵ N/m²

Pressure exerted by a liquid (density d) column at a depth h, = d h g

So pressure is directly proportional to the depth in a liquid.

Hence ratio = h1 / h2 = P1 / P2 = 3/5 = 0.6

pressure at the depth h2 = P2 = 5 * 10⁵ N/m²

Pressure exerted by a liquid (density d) column at a depth h, = d h g

So pressure is directly proportional to the depth in a liquid.

Hence ratio = h1 / h2 = P1 / P2 = 3/5 = 0.6
