Correct Answer: 36%


Solution : As per the given graph:
The inflation rate in the Third World in the year 1975 = 26.6
The inflation rate in the Third World in the year 1987 = 36.2
Increase in the inflation rate from 1975 to 1987 = 36.2 – 26.6 = 9.6
The required inflation percentage rate = $\frac{\text{Increase in the inflation rate from 1987 to 1975}}{{\text{The inflation rate in the Third World in the year 1975}}}×100$
The required inflation percentage rate = $\frac{9.6}{26.6}×100$ = 36.09%
The required inflation percentage rate $\approx$ 36%
Hence, the correct answer is 36%.
