Read this question in English
In a T20 cricket match, three players X, Y and Z scored a total of 37 runs. The ratio of number of runs scored by X to the number of runs scored by Y is equal to ratio of number of runs scored by Y to number of runs scored by Z.
Value-I. Runs scored by X
Value-II. Runs scored by Y
Value-III. Runs scored by Z
Which one of the following is correct?
(a) Value-I < Value-II < Value-III · (b) Value-III < Value-II < Value-I · (c) Value-I < Value-III < Value-II · (d) Cannot be determined due to insufficient data
उत्तर और व्याख्या · explanation in English
Answer: (d) अपर्याप्त आँकड़ों के कारण निर्धारित नहीं किया जा सकता
The condition only says X, Y and Z are in geometric progression with a total of 37. Both 16, 12, 9 and 9, 12, 16 satisfy it, giving opposite orders, so the comparison cannot be determined.
- X : Y = Y : Z means Y² = X × Z, with X + Y + Z = 37.
- Try Y = 12: then X × Z = 144 and X + Z = 25, so X and Z are 16 and 9.
- Both (X, Y, Z) = (16, 12, 9) and (9, 12, 16) fit: 16 × 9 = 144 = 12², and the total is 37.
- The first gives Value-III < Value-II < Value-I; the second gives Value-I < Value-II < Value-III.
- The order cannot be fixed from the data.
Remember · For a 'cannot be determined' option, try to build two valid cases with different orders; one such pair settles it.
