From the question, it can be concluded that with an increase in each reading, the strength will be increased 10 times.
Thus, from the question, A’s strength = 2 on the Richter scale
10 times A’s strength = 3 on the Richter scale
100 time = 4 on Richter scale
1000 times = 5 on Richter scale.
Thus, the answer will be 5.
