There are two huts of two brothers each on the opposites sides of a medium sized pond. Each brother has to use 12 stones in the pond to visit each other’s hut by crossing the pond. These stones are numbered serially using numbers one to twelve. A dragon fly is jumping on these stones as follows; every minute it jumps to the fifth stone from where it started. Thus if it jumps from the fourth stone it would go to the ninth stone, from the ninth stone it would go to the second stone and so on. Select the option that indicates the number of stones on which this dragon fly would be resting if it stops jumping at the 36th minute if it starts jumping from the stone that is numbered two.
Consider the following statements in respect of arched construction made of voussoirs: 1. The superimposed load is transferred to the sidewalls only by the strength of cohesion of the mortar between the voussoirs. 2. The arch may fail under crushing when the compressive stress or thrust in it exceeds the safe crushing strength of the voussoir material. 3. Every element in the arch is subjected to compression only. 4. Failure of the arch due to the sliding of any voussoir past the adjacent one due to transverse shear can be avoided by reducing the height of the voussoirs. Which of the above statements are correct?
