A cooperative society has 720 members, of whom 432 are women. What is the ratio of men to women members in simplest form?
The ratio of men to women is 2 : 3. Men number 720 minus 432, which is 288. The ratio 288 : 432 reduces by the common factor 144 to 2 : 3. Reversing the order would wrongly give 3 : 2.
- A2 : 3Correct
- B3 : 2
- C3 : 5
- D5 : 3
Explanation
Men = 720 - 432 = 288. Ratio men : women = 288 : 432. Dividing both by 144 gives 2 : 3. Option 3 : 2 reverses the order, and 3 : 5 compares women to total or men to total wrongly.
