  2. BOption (b)

    257 - 73

View answer & explanation

Correct answer

Answer: (d)D.

421 - 10

Why this answer is correct

The following pattern is,

167 - 45 → (1 × 6 × 7) + 3 = 45

257 – 73 → (2 × 5 × 7) + 3 = 73

517 - 38 → (5 × 1 × 7) + 3 = 38

But in 421 - 10, (4 × 2 × 1) + 2 = 10 which is not equal to 11.

Thus, 421 – 10 is odd one.

Question 38

Bihar Jeevika 2025• Test

The statements below are followed by two conclusions labeled I and II. Assuming that the information in the statements is true, even if it appears at variance with generally established facts, decide which conclusion(s) logically and definitely follow(s) from the information given in the statements.

Statements:

All spiders are snails.

All molars are snails.

Conclusion:

I. No spider is a molar.

II. Some spiders are molars.

  1. AOption (a)

    Only conclusion II follows.

  2. BOption (b)

    Only conclusion I follows.

  3. COption (c)

    Either conclusion I or conclusion II follows.

  4. DOption (d)

    Both conclusions follow.

View answer & explanation

Correct answer

Answer: (c)C.

Either conclusion I or conclusion II follows.

Why this answer is correct

Concept:

  • The neither-nor case is applicable when both the conclusions are false, whether definite or not.
  • The either-or case is applicable for a pair of statements only if either of the following pair of keywords is used AND only if the following conditions are satisfied:

Keywords:

  1. All and some not
  2. Some and no

Conditions:

  1. The same elements are used in the two conclusions. For example, in this case, the elements jungles and malls are common to both conclusions.
  2. Both conclusions should be possibilities. That is, they should be false because the conclusion is possible but not definite.

Then, the pair of conclusions are considered as complementary pairs.

The least possible Venn diagram is,

Conclusion I: No spider is a molar → False (This is definitely false)

Conclusion II: Some spiders are molars → False (This is possible but not definite)

Explanation:

In the given question, the keywords provided (Some and no) satisfy the concept of the Either-or case.

Conclusion I and Conclusion II form a complementary pair.

Hence, “either conclusion I or conclusion II” follows.
