Show Answer
Correct Answer: (2)
Solution: (2) Number of magazines sold in city $K$ in :
Year $2016 \Rightarrow 87600 \times \frac{16}{100}$
$=14016$
Year $2017 \Rightarrow 96900 \times \frac{15}{100}$
$=14535$
Required percentage
$=(14535-14016) \times\left(\frac{100}{14535}\right)$
$=\frac{519 \times 100}{14535} \approx \frac{520 \times 100}{14500}$
$\approx 3.586 \% \approx 4 \%$
