Question

Raman 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 offers the safest option?

• A.
• B.
• C.
• D.

Answer 1

The correct option is C

Raman must take the occurrence of earthquakes in a country under consideration before purchasing the house. The Richter scale determines the intensity of earthquakes. Greater the Richter scale value, more 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, Raman should purchase a house in country 3.
