A ship is 40 km away from shore. There is a hole in the ship from which \(\frac{{15}}{4}\) tons of water come in the ship in every 12 mins. There is another outlet tap that throws out 12 tons of water every hour. Find at what speed it should move such that when it begins to sink a rescue ship moves with 2 km/hr escapes the passengers of the ship if 60ton of water is enough to sink?
An object X sinks in liquids P and Q but floats in liquid R. Which of the following conclusions can be made from these observations? A) Density of X is more than the density of P B) Density of X is less than the density of R C) Density of P is equal to the density of R D) Density of P is less than the density of R
A ship can row at a speed of 7 km/hr in still water while the speed of stream is 2 km/hr. Ship rowing upstream from point A to point B, after travelling to point k which is midpoint of A and B, ship failed to work. The ship retuned along the stream and reached the point A again. In this process ship takes 6 hrs more time than it takes in reaching to point B. 60% of the total distance is:
A ship 70 km from the shore springs but accidentally ship strikes an iceberg which creates damage due to which ship admits 2.5 tons of water in 6 minutes. 90 tons would suffice the ship to sink, but the pumps can throw out 15 tons an hour. What would be the average rate of sailing so that the ship reaches the shore before sinking?
Seven contestants, H, I, J, K, L, M and N, have their entry on stage at the Miss World contest in a certain sequence. I enters exactly before M. J enters exactly after N. Exactly one contestant enters on stage after M and before H in the same order. L enters third. H enters last. Based on the given information, which of the following options is true?
There are six friends who have different height and they stand according to their height information as given below. Q is greater than P and S. M is greater than P. T is greater than P who is greater than O. M is greater than Q. T is smaller than Q. Who among the following is the smallest in height?
A ship of height 15 meter is sinking at the rate of 1 meter/minute. This incident is happening 39 km away from the rescue team's ship, at what speed rescue team's ship should run to reach the sinking ship when 2 meter of the sinking ship is remaining to sink.
A ship is 180 km from the shore and the ship gets pierced and within 18 minutes 3.75 tons of water starts going in. The vessel pumps out 10.5 tons of water in one hour. 30 tons of water can sink the ship. How much does the ship keep its average speed to reach the shore immediately before sinking?
The time taken by a ship to travel 1000 km upstream is 40 hours more than the time taken by it to travel the same distance in downstream. The speed of the ship in still water is 200% more than that of the speed of stream. Quantity I: How much time the ship will take to travel the same distance in upstream?  Quantity II: How much time the ship will take to travel 2000 km downstream if due to wind, the speed of stream was increased by 50%?
