- A.
2

- B.
3

- C.
5

- D.
7

Answer: Option D

**Explanation** :

There are 10 employees who are engaged in both complex and medium operations.

**For employee 2001148:**

The amount earned in Medium operations = 513.26 − 51.53 − 3 = 458.73

$\frac{51.53}{3.33}<\frac{458.73}{1.67}$

**For employee 2001151:**

The amount earned in Medium operations = 282.81 − 171.71 − 79.1 = 32

$\frac{171.71}{5.5}>\frac{32}{4}$

**For employee 2001155:**

The amount earned in Medium operations = 597.94 − 497.47 − 100.47 = 0

Hence, the average amount earned per day in Medium operations = 0/4.67 = 0

Hence, the average amount earned per day in Complex operations is more.

**For employee 2001159:**

$\frac{594.43}{9.67}>\frac{159.64}{13.33}$

**For employee 2001162:**

$\frac{472.51}{1.29}>\frac{109.73}{9.71}$

**For employee 2001165:**

$\frac{402.25}{5.27}>\frac{735.72}{12.07}$

**For employee 2001169:**

$\frac{288.48}{8.38}>\frac{6.1}{4.25}$

**For employee 2001170:**

$\frac{812.1}{10}>\frac{117.46}{8.5}$

**For employee 2001177:**

$\frac{46.56}{2}<\frac{726.19}{19}$

**For employee 2001180:**

$\frac{116.4}{5}<\frac{1262.79}{19}$

∴ There are 7 employees for whom per day earnings in complex operations is more than per day earnings in medium operations.

- A.
0

- B.
1

- C.
2

- D.
None of these

Answer: Option C

**Explanation** :

The average increase in income before taxes and charges from 1998 to 1999 (ignoring the loss making operations)

**33. CAT 2002 LRDI | LR - Directions**

What is the total distance covered by the man till the last signal?

- A.
90 km

- B.
120 km

- C.
110 km

- D.
84 km

Answer: Option A

**Explanation** :

The movement can be tabulated as below:

Distance = $20\times \frac{1}{2}+40\times \frac{1}{4}+40\times \frac{1}{2}+100\times \frac{2}{5}+40\times \frac{1}{4}$

= 10 + 10 + 20 + 40 + 10

= 90 km

Hence, option (a).

If the first signal after the starting point, is 1 Red and 2 Green lights, then what is the total distance covered by the man till the last signal?

- A.
90 km

- B.
50 km

- C.
40 km

- D.
80 km

Answer: Option A

**Explanation** :

Since only the direction of the man has changed, the total distance covered by him will still remain the same.

∴ Total distance = 90 km

Hence, option (a).

**36. CAT 2002 LRDI | LR - Directions**

Instead of heading North, if the man was heading South, then by the end of the journey, he was

- A.
50 km towards South, 50 km towards West from his starting point.

- B.
50 km towards North, 50 km towards West from his starting point.

- C.
60 km towards North, 40 km towards West from his starting point.

- D.
40 km towards South, 30 km towards West from his starting point.

Answer: Option D

**Explanation** :

If instead of North, the man headed for South, the map given in the solution of the second question in the set will get inverted and flipped.

∴ He will end up south-west of his starting position, instead of north-east.

∴ He ends up at 30 km West and 40 km South of his starting point.

Hence, option (d).

**Answer the following question based on the information given below.**

A causes B or C, but not both.

F occurs only if B occurs.

D occurs if B or C occurs.

E occurs only if C occurs.

J occurs only if E or F occurs.

D causes G or H or both.

H occurs if E occurs.

G occurs if F occurs.

If A occurs, which may occur?

I. F and G

II. E and H

III. D

- A.
I only

- B.
II only

- C.
III only

- D.
Either I and III or II and III, but not both.

Answer: Option D

**Explanation** :

A causes B or C, but not both.

In either case, D occurs.

F can occur only if B occurs, while E can occur only if C occurs. Since only one of B and C can occur, hence only one of F and E can occur.

Hence, option (d).

Which of these may occur as a result of a cause not mentioned?

- A.
E

- B.
Both E and F

- C.
Either B or C

- D.
J

Answer: Option C

**Explanation** :

**Consider option 1:**

E occurs only if C occurs,

∴ E cannot occur because of a cause not mentioned.

**Consider option 2:**

E occurs only if C occurs and F occurs only if B occurs,

∴ E and F both cannot occur as a result of a cause not mentioned.

**Consider option 4:**

J occurs only if E or F occurs,

∴ J also cannot occur as a result of a cause not mentioned.

**Consider option 3:**

It is given that A causes B or C but not both,

∴ Either B or C can occur by a cause not mentioned.

Hence, option (c).
