A and B enter into partnership with capital as 7:9. At the end of 8 months, A withdraws. If they receive the profits in the ratio of 8:9 find how long B's capital was used?
Correct answer: D. 7 months
- A. 6 months
- B. 8 months
- C. 10 months
- D. 7 months
Explanation
A's capital is used for 8 months, giving a capital-time value of 7 x 8 = 56 capital-months. If B's capital of 9 is used for t months, the profit ratio condition gives 56:9t = 8:9, so 56 = 8t and t = 7 months. The likely mistake is option b, 8 months, which forgets that B's duration must be calculated rather than assumed to equal A's duration.

About Ratio and Proportion
Ratios compare quantities in the same units, while proportions state that two ratios are equal. Problems cover simplification, division in a given ratio, direct and inverse variation, scale, and missing terms, with attention to the difference between a ratio and a fraction representing part of a whole.
