11. A car dealer marks the price of a car at 15% above its price and allows a discount of 7(1/2%), if the payment is being made through cash. Find the percentage of profit that the dealer will make in this deal.

1. 6(1/2%)
2. 6(8/3%)
3. 6(3/8%)
4. 6%
5. None of the above

Answer: c)

Explanation: Let the Cost Price be Rs. 100.

Marked Price = Rs. 115

Discounted Price = 7(1/2%) of Rs. 115 = 69/8

Reduced Price = Rs. (115 – 69/8) = 851/8

Profit % = (851/8 – 100) = 51/8 = 6(3/8%)

12. Find the approximate amount of compound interest that will be obtained at the end of 5 years, if Ms. Apurva invests a sum of Rs.10000 at the rate of 10%?

1. 6205
2. 6105
3. 6305
4. 6504
5. None of the above

Answer: b)

Explanation: C.I = 10000 [(1 + 10/100)⁵ – 1]

= 10000 (11/10 × 11/10 × 11/10 × 11/10 × 11/10 – 1)

= 10000 (161051 – 100000/100000)

= 61051/10 = Rs. 6105 (approx.)

Directions (13 – 17) – Read the given below table carefully and Answer: the following questions:

13. In the year 2012 the number of students enrolled in course ‘Computer Science’ is what per cent of the total number of students enrolled in all courses in the same year (rounded off to two places of decimal)?

1. 79
2. 21
3. 88
4. 31
5. None of the above

Answer: a)

Explanation: The number of students enrolled in course ‘Computer Science’ in year 2012 = 132

The number of students enrolled in all courses in the same year

= 136 + 96 + 132 + 124 + 158 + 140 = 786

Hence, the required percentage

= 132/786 × 100 = 16.79

14. For all the given years, what is the difference between the average number of students enrolled in course ‘Information Technology’ and ‘Civil’?

1. 37
2. 33
3. 32(2/3)
4. 37(1/3)
5. None of these

Answer: d)

Explanation: Average number of students enrolled in course ‘Information Technology’

= (120 + 112 + 124 + 135 + 118 + 128)/6 = 737/6

Average number of students enrolled in course ‘Civil’

= (140 + 152 + 158 + 166 + 170 + 175)/6= 961/6

Hence, required difference = 961/6 – 737/6

= (961 – 737)/6 = 224/6 = 37(1/3)

15. In which year percentage increase/decrease in the number of students enrolled is the minimum for course ‘Metallurgical’?

1. 2011
2. 2012
3. 2013
4. 2014
5. 2015

Answer: e)

Explanation: In 2011, decrease% = 4/136 × 100 » 2.94

In 2012, increase% = 8/132 × 100 » 6.06

In 2013, decrease% = 14/140 × 100 » 10

In 2014, increase% = 20/126 × 100 » 15.87

In 2015, increase% = 4/146 × 100 » 2.74 (minimum)

16. For all the given years, in which course the average number of students enrolled in that course was the maximum?

1. Information Technology
2. Mechanical
3. Computer Science
4. Civil
5. None of these

Answer: d)

Explanation: The course which shows the total number of students enrolled the highest must have average number of students enrolled the maximum.

Hence average number of students enrolled in course ‘Civil’ is the maximum.

17. What is the approximate ratio of the number of students enrolled in all the courses in 2010 to that in 2011?

1. 13 : 14
2. 37 : 36
3. 10 : 9
4. 13 : 11
5. 4 : 3

Answer: b)

Explanation: The number of students enrolled in 2010 = 145 + 88 + 115 + 120 + 140 + 136 = 744

The number of students enrolled in 2011 = 128 + 76 + 122 + 112 + 152 + 132 = 722

Required ratio = 744: 722 » 37:36

Directions (24 – 30): Read the following passage and Answer the questions that follow:

India’s economy continues to decelerate with the government’s estimate for first-quarter gross domestic product pegging growth at a 13-quarter low of 5.7% in April-June. The reasons for the protracted slowdown — a slide of five straight quarters from 9.1% in March 2016 — are many and varied. But there is little doubt that the demonetisation exercise combined with the uncertainty around the July 1 adoption of the new indirect tax regime served to significantly dampen economic activity. While the GST-related “inventory de-accumulation” that Chief Statistician T.C.A. Anant referred to may well be reversed in the current quarter as companies across sectors gain comfort with the new tax regime, it is still doubtful whether demand for industrial output is going to attain any meaningful strength. The Reserve Bank of India last month said that its industrial outlook survey had “revealed a waning of optimism in Q2 about demand conditions across parameters and especially on capacity utilisation, profit margins and employment.” A look at the sector-specific trends shows that manufacturing expansion in gross value added (GVA) terms has slackened to a near stall at 1.2%. This, from 5.3% in Q4 of the last fiscal and 10.7% a year earlier, is a far from heartening sign. With capacity utilisation expected to weaken this quarter, according to the RBI, and with surveys suggesting that consumer sentiment has deteriorated steadily in August, the auguries for a demand rebound are far from promising.

While expressing concern about the slower-than-expected expansion, the Finance Minister has acknowledged that the challenge before the government now is to work out both policy and investment measures to boost momentum. One option would be to suspend the fiscal road map for a limited period in order to pump prime the economy through increased capital spending by the government. The risks of fiscal loosening are of course manifold, especially at a juncture when several State governments have either announced or are contemplating large-scale farm loan waivers, which would push up interest rates and crowd out fresh lending. Still, there is a thin sliver of a silver lining in the GDP data. The services sector continues to remain buoyant. Quarterly GVA across this broad swathe that encompasses trade, hotels, transport, communication and broadcasting accelerated to 11.1%, from 6.5% in the fourth quarter, faster than the 8.9% posted in the corresponding period last year. The civil aviation sector saw passenger traffic soaring by 15.6%, and construction activity, a provider of jobs, also ticked up by 2%. The Finance Minister has his task cut out: to find ways to restore momentum before the tailwinds of low inflation and affordable energy prices start reversing direction.

24. Which one of the following statements is false regarding the present GDP growth rate of India?

1. Growth rate fell to 5.7%.
2. Growth rate fell at a 13-quarter low
3. Growth rate is climbing at an increase rate
4. Decelerated growth rate is prevailing
5. None of the above

Answer: c)

Explanation: The first paragraph clearly indicates that the GDP growth is moving at a decreasing rate. Hence, option c) is incorrect.

25. What does the term ‘inventory de-accumulation’?

1. Decrease in the number of warehouses.
2. Decrease in the value of stock.
3. Increase in the number of warehouses.
4. Increase in the value of stock.
5. None of the above

Answer: b)

Explanation: The term ‘inventory de-accumulation’ means decrease in the value of stock or inventory.

26. Which of the following statement is correct according to the passage?

1. Quarterly Gross Value Added (GVA) accelerated to 6.5% this quarter.
2. The civil aviation sector saw passenger traffic decreasing by 15.6%.
3. Construction activity growth rate increased by 2%.
4. Expansion in gross value added (GVA) has slackened to a near stall at 2.2%.
5. None of the above

Answer: c)

Explanation: The second paragraph clearly states that the civil aviation sector saw passenger traffic soaring by 15.6%, and construction activity, a provider of jobs, also ticked up by 2%. Hence, option c) is correct.
