The number of satellites launched by Belgium is what percent of the number of satellites launched by Norway ?
84.44%
83.33%
82.22%
80.55%
None of the above
83.33%
Since the total (12000) is the same for both, simply find the ratio of their percentage shares: 1815тАЛ├Ч100.
Total satellites = 12000. Pie chart distribution: Norway = 18%, Belgium = 15%.

Since the total (12000) is the same for both, simply find the ratio of their percentage shares: 1815тАЛ├Ч100.
Calculating the actual number of satellites for each country (1800 and 2160) adds unnecessary steps and increases the risk of arithmetic errors.
Identify percentage shares
From the pie chart, Norway has 18% of the total, and Belgium has 15% of the total.
ShareNorwayтАЛ=18%,ShareBelgiumтАЛ=15%
Calculate the ratio
Since both are percentages of the same base (12000), we calculate the ratio of their shares: 1815тАЛ.
1815тАЛ=65тАЛ
Convert to percentage
Multiply the fraction by 100 to get the percentage value.
65тАЛ├Ч100%=83.33%
B is correct because the ratio of Belgium's 15% share to Norway's 18% share is 65тАЛ, which equals 83.33%.
In Data Interpretation problems, always look for ratios first to cancel out common totals before performing complex multiplication.
