5. Buyers pay pearl divers with gold and corn. After consulting, the buyers decided to reduce the price "in gold" by 5% on the first island. Then the price "in corn" will drop by $7 \%$, as the prices of gold and corn are linked in the market.

For the pearl divers of the second island, due to the arrival of a cold current, the price reduction was decided to be less - "in gold" by $1 \%$. By what percentage will the price of pearls "in corn" drop for the divers of the second island? Round your answer to two decimal places after the decimal point.
Solution. Let x be the original price of the pearl; for the first island: $0.95 x$ in "gold"; $0.93 x$ - in "corn". Their ratio $\frac{95}{93}$ is constant in the market. For the second island: 0.99 x in "gold", $y$ - in "corn"; $\quad \frac{0.99 x}{y}=\frac{95}{93} ; y=\frac{0.99 x \cdot 93}{95}$. The pearl became cheaper $\left(1-\frac{0.99 \cdot 93}{95}\right) x=\frac{95-92.07}{95} x=\frac{2.93}{95} x$. In percentages $\frac{2.93 x \cdot 100 \%}{95 x}=\frac{293}{95}=3.08$

Answer: 3.08 .
