Question

What will be the total weight of 20 bars, each of the same weight ? Statements: I : One-fifth of the weight of each bar is 6 kg. II : The total weight of fivebars is 90 kilograms more than the total weight of two bars.

• A. If the data in statement I alone is sufficient to answer the question, while the data in statement II alone is not sufficient to answer the question
• B. If the data in statement II alone is sufficient to answer the question, while the data in statement I alone is not sufficient to answer the question
• C. If the data either in statement I alone or in statement II alone are sufficient to answer the question
• D. If the data given in both statements I and II together are not sufficient to answer the question
• E. If the data in both statements I and II together are necessary to answer the question.

Answer 1

The correct option is C

If the data either in statement I alone or in statement II alone are sufficient to answer the question

From I, we conclude that weight of each bar = $(5\times 6)kg=30kg.$

So, total weight of 20 bars = $(20\times 30)kg=600kg.$

From II, we conclude that: Weight of each bar = (weight of 5 bars) - (weight of 2 bars) = 90 kg.

So, total weight of 20 poles = (20 \times 30) kg = 600 kg
