Show Answer

Correct Answer: (1)

Solution: (1)

Number of elephants in both reserves in 2002 $=42+28=70$

Number of African elephants $=\frac{70 \times 40}{100}=28$

Number of elephants in both reserves in 2004 $=44+56=100$

Number of African elephants $\Rightarrow 65 \%$ of $100=65$

Required difference $=65-28=37$
