根据给定的陈述，选择最合适的选项来解决给定的问题。
10 个相同重量的杆子的总重量是多少?
Statements:
(I) One fourth of the weight of a pole is 5 kg
(II) The total weight of these poles is 160 kg more
than the total weight of two poles. (A)仅陈述 II 是不够的
(B)仅陈述 II 是不够的
(C)单独使用 I 或 II 就足够了
(D)陈述 I 和 II 放在一起是不够的。答案： (C)
解释：
(I) is sufficient. We can determine total weight of 1o
poles as 10 * 4 * 5 = 200 Kg
(II) is also sufficient, we can determine the weight.
Let x be the weight of 1 pole.
10*x - 2*x = 160 Kg
x = 20 Kg
10x = 200 Kg 这个问题的测验
