Explanation

• The primary purpose of microorganisms such as bacteria is to decompose dead organic matter and recycle nutrients.
• Bacteria break down dead plants, animals, and organic waste.
• This process returns nutrients to the soil, making them available for new life.
• Without decomposers, dead matter would accumulate, and nutrient cycling would stop.

Explanation

Let's arrange 9 people: A, B, C, D, E, F, G, H, I

Given:

1. G is the last person in the line.

2. A is after B, and A is before D → B ... A ... D

3. There are exactly three people between B and D → B _ _ _ D

4. H stands immediately after D → D H

5. C is immediately before F → C F

6. There are exactly two people between A and C → A _ _ C

7. E stands somewhere between F and I → F ... E ... I or I ... E ... F

8. I is before G

From (1), G is last. So position 9 = G.

From (3) and (4): B _ _ _ D H  

From (6): A _ C F  

From (5): C F are together  

From (2): B comes before A

Combining, one valid arrangement is:  

1. B  

2. I  

3. A  

4. C  

5. F  

6. E  

7. D  

8. H  

9. G  

Check all conditions:

A after B, before D ✓  

C immediately before F ✓  

2 people between A and C: A, C, F → yes ✓  

G last ✓  

H immediately after D ✓  

E between F and I: F, E, D... and I is before F ✓  

I before G ✓  

3 people between B and D: B, I, A, C, D → 3 people between ✓ 

Last person is G.

Explanation

Start at point O.

1. Walk 10 m north  

2. Walk 15 m east  

3. Walk 10 m south  

Net movement north-south: 10 m north - 10 m south = 0 m  

Net movement east-west: 15 m east  

So final position is 15 m east of the starting point.  

He is in the East direction from the starting point.

Explanation

P is the son of Q.  

Q is the sister of R.  

R is the father of the man.  

So:  

R is the father of the man → The man is R's son.  

Q is R's sister → Q is the man's aunt.  

P is Q's son → P is the son of the man's aunt.  

Son of aunt = Cousin.  

So the man is the Cousin of P.
