Directions: Read the following pie charts carefully and answer the questions…

In a percentage-based pie chart, a sector's value equals the chart's total quantity multiplied by that sector's percentage share. When two pie charts describe overlapping categories for the same shops (one chart giving rings-and-bracelets combined, another giving rings alone), subtracting a shop's rings-alone value from its combined value isolates that shop's bracelets figure. Once one term of a given ratio is known, the other term follows by scaling with the ratio's remaining factor.

1. From Pie Chart II (Rings Sold = 200): rings sold by Shop II = 35% of 200 = 70, and rings sold by Shop IV = 40% of 200 = 80.

2. Rings sold by Shops II and IV together = 70 + 80 = 150.

3. Chains sold by Shop I are 20% less than this combined rings figure, so chains sold by Shop I = 80% of 150 = 120.

4. The ratio of chains sold by Shop I to Shop II is 4 : 7, so chains sold by Shop II = 120 multiplied by 7/4 = 210.

5. From Pie Chart I (Rings and bracelets together = 440): the combined rings-and-bracelets total for Shop II = 30% of 440 = 132.

6. Bracelets sold by Shop II = combined Shop II total minus rings sold by Shop II = 132 minus 70 = 62.

7. Chains and bracelets sold by Shop II = 210 + 62 = 272.

Cross-check: both pie charts' percentages sum to 100% (25+30+10+35 and 18+35+7+40), and 120 is exactly 80% of 150, confirming the 20%-less condition; also 120 to 210 simplifies to 4 to 7, confirming the given chains ratio.

So the total number of chains and bracelets sold by Shop II is 272.
