Either I or II is sufficient
- D.
Neither I nor II is sufficient

Show answer & explanation
Correct answer: C
Using statement I: One-fourth of the weight of each pole is 5 kg, so each pole weighs 4 × 5 = 20 kg.
Therefore, the total weight of 10 poles = 10 × 20 = 200 kg.
Using statement II: Let the weight of each pole be w. The total weight of three poles is 20 kg more than that of two poles, so 3w = 2w + 20, which gives w = 20 kg.
Therefore, the total weight of 10 poles = 10 × 20 = 200 kg.
Conclusion: Each statement alone is sufficient to determine the total weight. The total weight of 10 poles is 200 kg.
