Correct answer

Answer: (b)B.

24

Why this answer is correct

Given: N rank 5th in the class, S is 8th from the last. If T is 6th after N and just in the middle of N and S.

Rank of N = 5th

Rank of S = 8th from last

Rank of T = 6th after N = 5 + 6 = 11th

T is just in middle of N and S which means number of students between N and T is equal to the number of students between T and S i.e., 6.

Now, rank of S from start is 11 + 6 = 17th

And rank of S from last is 8th

Total number of students = Rank from start + Rank from last - 1

Total number of students = 17 + 8 - 1 = 24

Hence, the correct answer is option (2).

If a 1 mm thick paper is folded so that the area is halved at every fold, then what would be the thickness of the pile after 50 folds?

  1. AOption (a)

    100 km

  2. BOption (b)

    1000 km

  3. COption (c)

    1 million km

  4. DOption (d)

    1 billion km

View answer & explanation

Correct answer

Answer: (d)D.

1 billion km

Why this answer is correct

Given:

Thickness of paper = 1 mm = 1 × 10-6  km

The thickness of paper after 1 fold = 2 mm

The thickness of paper after 2 fold = 22 mm

The thickness of paper after 50 fold = 250 mm

x = 250 × 10-6 km

x =  250 /106

Taking log on both sides

log x = 50 × log2 - 6 × log10

⇒ log x = 50 × 0.3010 - 6 × 1

⇒ log x = 15.05 - 6

⇒ log x = 9.05

⇒ log x ≈ 9

⇒ x = anti log 9

⇒ x = 109 km

⇒ x = 109 km

⇒  x = 1 billion km

∴ The thickness of the pile after 50 folds is 1 billion km.

Question 80

Territorial Army 2022• Reasoning

Directions

In the following questions, clues are given regarding comparisons among set of persons, things, direction, age, time, numbers etc. You are required to analyse the whole information and answer the given question accordingly.

A was born 2 years after his father’s marriage, his mother is 5 years younger than his father, but 20 years older than A, who is 10 years old. At what age did the father get married?

  1. AOption (a)

    35 years

  2. BOption (b)

    25 years

  3. COption (c)

    23 years

  4. DOption (d)

    33 years

View answer & explanation

Correct answer

Answer: (c)C.

23 years

Why this answer is correct

Given:

Age of A = 10 yrs

Age of A's mother = 10 + 20 = 30 yrs

Age of A's father = 30 + 5 = 35 yrs

Now age of A's father when A was born = 35 - 10 = 25 yrs

We have, A was born 2 years after his father’s marriage, so

the age of A's father when he got married → 25 - 2 = 23 yrs.

Hence, the correct answer is option (3).
