Question

What will be the total weight of 10 poles, each of the same weight ?Statements:
1. One-fourth of the weight of each pole is 5 kg.
2. The total weight of three poles is 20 kilograms more than the total weight of two poles.

• A. I alone is sufficient while II alone is not sufficient
• B. II alone is sufficient while I alone is not sufficient
• C. Either I or II is sufficient
• D. Neither I nor II is sufficient
• E. Both I and II are sufficient

Answer 1

Answer: (C)

Either I or II is sufficient

From I, we conclude that weight of each pole = (4x5) kg = 20 kg.
So, total weight of 10 poles = (20 x 10) kg = 200 kg.
From II, we conclude that:
Weight of each pole = (weight of 3 poles) - (weight of 2 poles) = 20 kg.
So, total weight of 10 pojes = (20 x 10) kg = 200 kg.
