Q2
Question : What will be the total weight of 10 poles, each of the same weight ? Statements : I. One-fourth of the weight of each pole is 5 kg. II. 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
AnswerD.
Neither I nor II is sufficient
E.
Both I and II are sufficient
Answer: Option C
Solution
Answer: Option C
Solution:
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.
