Q153. A man has two articles A and B. To find the selling price of article B, which statement or statements are required to answer the question? A. The total amount received by a man after selling six articles A and four articles B is Rs. 240. From this total amount, he could buy either nine articles A and four articles B or three articles A and eight articles B. B. The ratio of profit percentages on selling article A and article B is the same. C. The total profit earned on selling one article B is Rs. 6 and the profit percentage on selling one article A is 25%. The selling price and the cost price of article B are Rs. 10 and Rs. 8 more than those of article A respectively. A) Either A and B together or B and C together are sufficient to answer the question B) Either A and B together or C alone is sufficient to answer the question C) Either A and C together or B and C together are sufficient to answer the question D) A, B and C together are sufficient to answer the question E) Either only B or B and C together are sufficient to answer the question

1. Either A and B together or B and C together are sufficient to answer the question
2. Either A and B together or C alone is sufficient to answer the question
3. Either A and C together or B and C together are sufficient to answer the question
4. A, B and C together are sufficient to answer the question

Correct answer: Either A and C together or B and C together are sufficient to answer the question

Solution

Statement C alone gives the difference between selling prices and cost prices of A and B, but not the exact value of SP of B. When combined with A, the total amount relation allows solving both prices; when combined with B, the equal profit-percentage condition plus the price difference also determines SP of B. Hence either A and C or B and C is sufficient.
