कुछ धनराशि A, B और C के बीच में p : q : r के अनुपात में वितरित की गई ।

निम्नलिखित कथनों पर विचार कीजिए :

  1. 1.यदि p, (q + r) से अधिक हो, तो A को अधिकतम अंश मिलेगा ।
  2. 2.यदि r, (p + q) से कम हो, तो C को न्यूनतम अंश मिलेगा ।

Read this question in English

An amount of money was distributed among A, B and C in the ratio p: q: r.

Consider the following statements:

1. A gets the maximum share if p is greater than (q + r).

2. C gets the minimum share if r is less than (p + q).

Which of the above statements is/are correct?

(a) 1 only · (b) 2 only · (c) Both 1 and 2 · (d) Neither 1 nor 2

उत्तर और व्याख्या · explanation in English

Answer: (a) केवल 1

If one part exceeds the other two combined, it certainly exceeds each of them, so A gets the most. But being less than the sum of the other two says nothing about being the smallest, as 1 : 3 : 2 shows.

  1. Statement 1: shares are positive, so p > q + r means p > q and p > r — A gets the maximum. Correct.
  2. Statement 2: take p : q : r = 1 : 3 : 2. Here r = 2 < p + q = 4, yet A, not C, gets the least. Incorrect.
  3. So only Statement 1 is correct.
  • ✓ 1. p > q + r forces p above both q and r.
  • ✗ 2. r < p + q can hold even when r is not the smallest, e.g. 1 : 3 : 2.

Remember · Test 'if … then' claims with a quick counterexample: 'greater than the sum' implies 'greatest', but 'less than the sum' does not imply 'least'.
