a) 41%
b) 56%
c) 40%
d) 38%
Answer: a
Explanation: Let 100 be the original population.
1st year’s population increased = 30%
So, Population after first year
= (100 + 30% of 100)
= 130
Population in second year increases by 40%,
Then Population
= (130 + 40% of 130)
= 182
The final population become 182 which was originally at 100.
It means there is 82% increment in the population in 2 years
So, Average increment = $$\frac{{82}}{2}$$ = 41%
