A leopard entered a city and attacked its natives, killing 17% of the population. 35% of the remaining population left the city out of the fear of the leopard, leaving only 248/70 residents. What was the initial population?
Answer & explanation
Correct answer: option 1
Let total = 100%
Dead = 17%
Remaining = 83%
Left the city = 83 x \(\frac{7}{20}\)%
Remaining = \(\frac{83 x 13}{20}\)% → 248170
100% → \(\frac{248170 x 20}{83 x 13}\) x 100
100 % → 460000
