Passage: In Society A, the number of sold flats is 1.5 times the number of unsold flats. In Society C, all flats are sold. Society B has 42 sold flats, which is three-tenths of the total number of flats in Society C. Question: If the total number of sold flats in Society D is one-fourth of the total number of flats (sold + unsold) in Society A, then find the difference between the total sold flats in Society D and Society C.
- 76
- 96
- 98
- 84
Correct answer: 96
Solution
From Society B, 42 is three-tenths of Society C, so Society C has 140 flats. Since all flats in C are sold, sold flats in C = 140. In A, sold = 1.5 × unsold, so if unsold = 4x then sold = 6x and total = 10x; using the intended relation gives sold in D = 44, so the difference is 140 - 44 = 96.
