Show Answer

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 $=(14535-14016) \times(\frac{100}{14535})$

$=\frac{519 \times 100}{14535} \approx \frac{520 \times 100}{14500}$ $\approx 3.586 \% \approx 4 \%$
