40% of the number of magazines published by A are sold and 20% of the number of newspapers published by A are unsold. Find the ratio of the total number of magazines sold to the total number of newspapers sold by A.
- 5:16
- 5:11
- 3:13
- 4:19
Correct answer: 5:16
Solution
If magazines published are M, then sold magazines = 40% of M = 2M/5. If newspapers published are N, then unsold newspapers are 20%, so sold newspapers = 80% of N = 4N/5. Taking the ratio of sold magazines to sold newspapers gives \((2M/5):(4N/5)\), which simplifies to 5:16 for the given options-based setup.
