What is the difference between number of people coming from R having age group A and those coming from Q having age group D?
Consider the following for the next three (03) items that follow:<br>The following Pie-Chart-I shows the people migrating to Delhi from different Indian States (P, Q and R are three different States and S is the combined group of other States) and Pie-Chart-II indicates the different age groups A, B, C and D of these migrating people for each State.<br>State distribution: P = 40\%, Q = 30\%, S = 20\%, R = 10\%.<br>Age distribution: A = 50\%, B = 15\%, C = 15\%, D = 20\%.
- A. 6,000
- B. 8,000 ✓
- C. 12,000
- D. 18,000
Correct Answer: B. 8,000
Explanation
Group R forms 10\% of the 8,00,000 total = 80,000. Age group A within R is 50\% of 80,000 = 40,000. Group Q forms 30\% of the total = 2,40,000. Age group D within Q is 20\% of 2,40,000 = 48,000. The numerical difference is 48,000 - 40,000 = 8,000.
