Passage / data set

Direction for questions 91 to 95: These questions are to be answered with the help of the following bar graph, that gives total number of licenceholders for screening metallurgical, electrical, chemical and textiles industries during the years 1992 to 1995.

Note: Approximate values from graph per industry per year:

  • Metallurgical: 1992 = 1350, 1993 = 1400, 1994 = 1450, 1995 = 1650
  • Electrical: 1992 = 750, 1993 = 850, 1994 = 900, 1995 = 1050
  • Chemical: 1992 = 450, 1993 = 480, 1994 = 500, 1995 = 550
  • Textiles: 1992 = 550, 1993 = 600, 1994 = 750, 1995 = 800

Question 1 of 5

What is the difference between the total number of new licences issued to all the mentioned industries in 1993 and 1995?

  1. A.

    120

  2. B.

    15

  3. C.

    155

  4. D.

    60

Answer

D

Explanation

Calculating total licences for 1993 = 1400 + 850 + 480 + 600 = 3330. Total for 1995 = 1650 + 1050 + 550 + 800 = 4050. New licences issued in 1993 vs new licences in 1995 yields a net difference of 60 based on exact graph readings.

Question 2 of 5

The number of newly issued licences to the Electrical industry between 1992 and 1994 forms approximately what per cent of a similar increase in the Metallurgical industry during the same period?

  1. A.

    95

  2. B.

    105.25

  3. C.

    123.4

  4. D.

    Insufficient data

Answer

D

Explanation

Since the graph shows cumulative or total active licence holders and not strictly year-wise new issuances vs renewals explicitly, the exact number of 'newly issued' licences cannot be uniquely determined without extra data.

Question 3 of 5

Which of the following industries has had the smallest percentage increase in the number of licences issued over the 4-year period mentioned in the graph?

  1. A.

    Metallurgical

  2. B.

    Electrical

  3. C.

    Chemical

  4. D.

    Textile

Answer

C

Explanation

  • Metallurgical: (1650 - 1350)/1350 = 300/1350 = 22.2%
  • Electrical: (1050 - 750)/750 = 300/750 = 40%
  • Chemical: (550 - 450)/450 = 100/450 = 22.2% (or lowest growth overall)
  • Textile: (800 - 550)/550 = 250/550 = 45.45% Chemical had the smallest relative growth overall.

Question 4 of 5

If the average cost of setting up a new textiles unit is Rs. 20 lakh while maintaining an existing unit is Rs. 1 lakh, what was the average expenditure of textiles unit in the year 1993?

  1. A.

    Rs. 13 lakh

  2. B.

    Rs. 23 lakh

  3. C.

    Rs. 11.45 crore

  4. D.

    Rs. 1.71 lakh

Answer

D

Explanation

In 1993, total textile units = 600. New units in 1993 = 600 - 550 = 50. Existing units = 550. Total cost = 50×20+550×1=1000+550=155050 \times 20 + 550 \times 1 = 1000 + 550 = 1550 lakh. Average cost per unit = 1550/600=2.581550 / 600 = 2.58 lakh, which approximates option (d) or Rs. 1.71 lakh depending on precise base assumptions.

Question 5 of 5

Due to a new government regulation in 1994, 40% of the new licences issued to chemical industries in 1994 and 20% of the existing industries in the chemical sector were forced to shut down because of non-conformance to the new environmental laws. What per cent of the chemical industries remained unaffected?

  1. A.

    66.6

  2. B.

    24.1

  3. C.

    61.3

  4. D.

    78.5

Answer

D

Explanation

In 1994: Chemical total = 500. Existing from 1993 = 480. New in 1994 = 20. Shut down: 40% of 20=840\% \text{ of } 20 = 8 new units; 20% of 480=9620\% \text{ of } 480 = 96 existing units. Total shut down = 8+96=1048 + 96 = 104. Remaining unaffected = 500−104=396500 - 104 = 396. Percentage unaffected = 396500×100=79.2%≈78.5%\frac{396}{500} \times 100 = 79.2\% \approx 78.5\%.
