If the people coming from a particular State belonging to S are 15\% and 24,000 in number, then what is the total number of migrating people belonging to the age group B?
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. 1.2 lac ✓
- B. 1.25 lac
- C. 1.30 lac
- D. 1.50 lac
Correct Answer: A. 1.2 lac
Explanation
Let the total number of people in combined group S be x. We are given 15\% of x = 24,000, which implies x = 1,60,000. Since S represents 20\% of the total migrants, the Total = 1,60,000 / 0.20 = 8,00,000. Age group B is 15\% of the total, so its population is 0.15 \times 8,00,000 = 1,20,000, which is 1.2 lac.
