View answer & explanation

Correct answer

Answer: (d)D.

10

Why this answer is correct

The correct answer is option 4 i.e. 10

Given number is 624739854

Now we add 1 in all even digits and subtract 1 from all odd digits.

After the arrangement we get:

735628945

The 5th digit from the left end is 2 and the 4th digit from the right end is 8. so the sum is 8 + 2 = 10

Hence, the correct answer is 10.

Question 188

Other Govt. Exams 2023• Reasoning Ability

Direction: In the following question assuming the given statements to be true, find which of the conclusion among the given conclusion is/are definitely true, and then give your answers accordingly.

Statement: K < B < C = D > M < H ≥ N

Conclusions:

I. K < N

II. B < D

  1. AOption (a)

    Only I follow

  2. BOption (b)

    Only II follow

  3. COption (c)

    Both I and II follow

  4. DOption (d)

    Either I or II follow

  5. EOption (e)

View answer & explanation

Correct answer

Answer: (b)B.

Only II follow

Why this answer is correct

Given Statement: K < B < C = D > M < H ≥ N

Conclusions:

I. K < N → False (As K < B < C = D > M < H ≥ N, there is no relation between K and N because there are opposite signs between K and N. So, it is false)

II. B < D → True ( As K < B < C = D > M < H ≥ N → B < D. So, it is true)

Hence, Only II follow.

Question 189

Other Govt. Exams 2023• Reasoning Ability

Directions**:** In the following question assuming the given statements to be true, find which of the conclusion among given some conclusion is/are definitely true and then give your answers accordingly.

Statements: X < Y < Z ≤ A ≤ B = C > D ≥ E < F < G

Conclusions:

I. C ≥ X

II. B > E

  1. AOption (a)

    Only I is true

  2. BOption (b)

    Only II is true

  3. COption (c)

    Both I and II are true

  4. DOption (d)

    Either I or II is true

  5. EOption (e)

    Neither I and II is true

View answer & explanation

Correct answer

Answer: (b)B.

Only II is true

Why this answer is correct

Given statements: X < Y < Z ≤ A ≤ B = C > D ≥ E < F < G

Conclusions:

I  C ≥ X → False (Given X < Y < Z ≤ A ≤ B = C > D ≥ E < F < G so from the statement C > X is true but C ≥ X is false because Y is only greater then X not Y is equal to X thus C ≥ X is false )

II B > E → True (Given X < Y < Z ≤ A ≤ B = C > D ≥ E < F < G thus B > E is true)

Hence, Only II is true.

Question 190

Other Govt. Exams 2023• Reasoning Ability

Direction: In the following question assuming the given statements to be true, find which of the conclusion(s) among given conclusions is/are definitely true and then give your answers accordingly.

Statement: E < F ≤ G > H ≥ K

Conclusions:

I. F > H

II. G < E

  1. AOption (a)

    Only conclusion I is true

  2. BOption (b)

    Only conclusion II is true

  3. COption (c)

    Either conclusion I or II is true

  4. DOption (d)

    Both conclusions I and II are true

  5. EOption (e)

    Neither conclusion I nor II is true

View answer & explanation

Correct answer

Answer: (e)E.

Neither conclusion I nor II is true

Why this answer is correct

Given statement: E < F ≤ G > H ≥ K

Conclusions: 

I. F > H → False (as E < F ≤ G > H ≥ K → F ≤ G > H → no clear relation between F and H can be determined as there are opposite signs between F and H. So, It is false)

II. G < E → False (as E < F ≤ G > H ≥ K → E < F ≤ G → E < G. So, it is false)

Hence, Neither conclusion I nor II is true.
