Question

Rahul wants to purchase a house in a country. He has to choose a place among four countries. The seismographic readings of four countries are given below. Among the given countries, which country should he choose for his purchase?

• A.
• B.
• C.
• D.

Answer 1

The correct option is D

Rahul must take the occurrence of earthquakes in a country under consideration before purchasing the house. The height of vibrations of the seismographic waves determines the intensity of earthquakes. The greater the height, the greater will be the intensity and vice-versa. Also, the number of waves counts for the number of earthquakes. It can be observed from the given seismographic records that earthquakes have occurred with minimum intensity in country 3. Hence, Rahul should purchase a house in country 3.
