Calculate the average interval, in years, between the start of each of the five major phases of Indian nationalism: Moderate Phase (1885‑1905), Extremist Phase (1905‑1919), Non‑Cooperation Movement (1920‑1922), Civil Disobedience Movement (1930‑1934), and Quit India Movement (1942‑1945).
Answer
14.25 years
The correct answer is 14.25 years — State the final answer: 14.25 years.
Step-by-step solution
- Determine the start year of each phase: 1885, 1905, 1920, 1930, 1942.
- Compute the differences between successive start years: \$1905-1885=20\$, \$1920-1905=15\$, \$1930-1920=10\$, \$1942-1930=12\$.
- Sum the four intervals: .
- Divide the total by 4 to find the average: years.
- State the final answer: 14.25 years.
Common mistake: Using end years instead of start years to compute intervals
Concept tested: Calculating average interval between movements
