**Explanation** :

Two projects are completed in 1998, one is Mumbai Heights and the second is Royal Holidays.

The cost of project is 250 + 225 = 475 crore. *Cost incurred = 475 + 47.5 = 522.5. (Students please note the last step. Rather than doing 1.1 × 475, it is convenient to do 475 + 10% of 475, which is = 475 + 47.5)

**Explanation** :

Four projects are completed in 1999. They are: (i) Majestic Holiday, (ii) Supremo Hotel, (iii) Windsor Manor and (iv) Leela Hotels. It is very much similar to previous situation.

The cost of project is 250 + 300 + 275 + 235 = 1060

Hence, the cost incurred = 1060 × (1.1)^{2} = 1282.6 crore

**Explanation** :

Students! read the question carefully. It says what is the cost of projects completed by 2000.

It will be addition of previous two answers + Cost incurred for the projects completed in 2000.

= (15 + 25 + 20 – 30 + 15) = 45

Total costs

= (330 + 290 + 90 + 260) = 970

Hence, profit/costs $=\frac{45}{970}$ = 4.6% = 5% (Approximately)

**Explanation** :

If the amount of tariff consumed by sector 1 is the same, then we can directly compare the tariffs to the two regions and get the answer.

****

Hence, we can see that as compared to 1991-92, the net tariff in 1994-95 increased by $\frac{(2172-2040)}{2040}=6.5\%$

**Additional direction: **The UPSEB supplies power under four categories: urban (25%), domestic (20%), industrial (40%) and rural (15%). In 1994-95, the total power produced by the UPSEB was, 7875 megawatts.

**30. CAT 1997 LRDI | DI - Tables & Graphs**

In 1994-95, if there was 10% decrease in the domestic consumption of power as compared to that in 1991-92, what was the consumption of power in the rural sector in 1991-92?

- A.
1,312 megawatts

- B.
1,422 megawatts

- C.
1,750 megawatts

- D.
None of these

Answer: Option A

Join our Telegram Channel for CAT/MBA Preparation.

**Explanation** :

In 1994-95, the power consumed by various sectors out of 7875 megawatts can be given as follows.

****

Since there was a 10% decrease in domestic consumption of power in 1994-95, the domestic consumption in 1991-92 = $\left(\frac{1575}{0.9}\right)$ = 1750 megawatts.

But this constitutes 20% of total power consumed in 1991-92 and the rural consumption constitutes 15% of total power in 1991-92. Hence, in 1991-92 the rural consumption = (1750 × $\frac{15}{20}$) = 1312 megawatts.

- D.
Cannot be determined

Answer: Option D

Join our Telegram Channel for CAT/MBA Preparation.

**Explanation** :

We only know the tariff rates for the two years for various regions and sectors. But we do not know the category-wise break-up of tariffs, i.e. the rates for urban sector is not known. In the light of this, we cannot answer this question.

Workspace:

**32. CAT 1997 LRDI | DI - Tables & Graphs**

Which of the following statements is true?

- A.
The average tariff in region 4 is 437.5 p/kWh

- B.
The average tariff in region 2 is greater than the average tariff in region 5

- C.
In 1991-92, the industrial sector contributed to about 42% of the total revenue from power

- D.
None of these

Answer: Option B

Join our Telegram Channel for CAT/MBA Preparation.

**Explanation** :

Let us evaluate each of the above statements.

The average tariff in region 4 $=\frac{(415+423+441+451)}{4}=432.5$ p/kwh

region 2 = $\frac{(472+468+478+470)}{4}=472$ p/kwh

region 5 = $\frac{(440+427+439+446)}{4}=438$p/kwh

Hence, the average tariff in region 2 is higher than in region 5. This statement is true. Note that we cannot evaluate the third statement at all.

**33. CAT 1997 LRDI | DI - Tables & Graphs**

In 1974, the amount of agricultural loans formed what percentage of the total loans?

- A.
85%

- B.
71%

- C.
77%

- D.
Cannot be determined

Answer: Option A

Join our Telegram Channel for CAT/MBA Preparation.

**Explanation** :

In 1974, agricultural loans amounted to

= Rs. 34.54 million. Loans from rural banks in 1974

= (260 × 98 × 243) = Rs. 6.19 million.

Hence, total amount of loans

= (34.54 + 6.19) = Rs. 40.73 million.

Hence, percentage of agricultural loans $=\frac{34.54}{40.73}=$ 84.79% = 85% (Approximately)

Workspace:

**34. CAT 1997 LRDI | DI - Tables & Graphs**

From the given data, the number of rural loans up to 1980 formed approximately what percentage of those in 1983?

- A.
112%

- B.
80%

- C.
97%

- D.
Cannot be determined

Answer: Option B

Join our Telegram Channel for CAT/MBA Preparation.

**Explanation** :

****

So the total number of loans up to 1980

= (2520 + 4485 + 6760 + 25480 + 38478 + 174240) = 251963

And the total number of rural loans in 1983 = 319200

Hence, $\frac{251963}{319200}=$ 78.93% = 80% (Approximately)

Workspace:

**35. CAT 1997 LRDI | DI - Tables & Graphs**

Which of the following pairs of years showed the maximum increase in the number of rural bank loans?

- C.
1970-71

- D.
1980-81

Answer: Option D

Join our Telegram Channel for CAT/MBA Preparation.

**Explanation** :

****

Thus, we find that the maximum increase in the number of loans for rural banks is in 1980-81.

**Note:** Students please note that we have not calculated the increase for 1970, 1980 and 1983 as their previous years’ figure is not known.

- A.
Rs. 326

- B.
Rs. 264

- C.
Rs. 305

- D.
None of these

Answer: Option B

Join our Telegram Channel for CAT/MBA Preparation.

**Explanation** :

The value of agricultural loan in 1983 is Rs. 915.7 million. But this at consumer price index (CPI) = 149.

So if we want this value at 1970 CPI, viz. 43, it would simply be $\frac{43\times 915.7}{149}=264.26$

What is the simple annual rate of increase in the number of agricultural loans from 1970 to 1983?

- A.
132%

- B.
81%

- C.
75%

- D.
1056%

Answer: Option C

Join our Telegram Channel for CAT/MBA Preparation.

**Explanation** :

From 1970 to 1983, in 13 years the number of agricultural loans went up from 18,300 to 2,11,600, an increase of 1,93,300. So percentage increase in this = $\frac{193300}{18300}$ = 1057. However, this growth is spread across 13 years. Hence, simple annual rate of increase = $\frac{1057}{13}$ = 81.3% = 81 (Approximately)

Workspace:

**Additional direction: **If the consumer price index for 1970 is to be taken as 105 and the indices for the subsequent years are to be corrected accordingly, then answer 184 and 185.

By roughly how many points do the indices for 1983 and 1975 differ?

- A.
174

- B.
180

- C.
188

- D.
195

Answer: Option A

Join our Telegram Channel for CAT/MBA Preparation.

**Explanation** :

The CPI in 1970 is 43. But it has to be taken as 105. Presently in 1983 and 1975, the CPI is 149 and 78 respectively. Hence, they should actually be taken as $\left(149\times \frac{105}{43}\right)$ = 363.83 and $\left(78\times \frac{105}{43}\right)$ = 190.46 respectively. Hence, their difference = (363.83 – 190.46) = 173.37 = 174 (Approximately).

Workspace:

**40. CAT 1997 LRDI | DI - Tables & Graphs**

What is the value of the loans in 1980 at 1983 prices?

- A.
Rs.570 million

- B.
Rs.680 million

- C.
Rs.525 million

- D.
Rs.440 million

Answer: Option B

Join our Telegram Channel for CAT/MBA Preparation.

**Explanation** :

Total value of loans = Rural bank loans + Agricultural loans.

Rural bank loan in 1980 = (605 × 288 × 567) = Rs. 98.79 million.

Total value of agricultural loan in 1980 = Rs.498.4 million.

Hence, total loans in 1980 = (98.79 + 498.4) = 597.19.

But this is at a CPI = 131

If it is to be calculated at 1983 CPI, viz. 149, then its value will be 597.19 × $\left(\frac{149}{131}\right)$ = Rs. 679.24 million = Rs. 680 million (Approximately).
