Question 1 of 10
1. Question
1 pointsCategory: Quantitative AptitudeDirections for Questions 15: The following graphs (Figure1 and 2) give the production and consumption od coal in certain countries of the world, as well as their reserves.
Shortfall/exess between production and consumption is met by imports/exports.
In the beginning of the year, Malaysia had coal stock of 3 million tonnes which rose to 5 million tonnes at the end of the year. Approximately, what percentage of its production is exported?
Correct
Solutions:
Malaysia’s production = 30 million tonnes, consumption = 19 million tonnes. This means a surplus of 11 million tonnes. However, there is only an increase of 2 million (from 3 to 5 million) in its reserves. This means that the exports = 9 million, which is 30% of 30 million. Hence, option d)Incorrect
Solutions:
Malaysia’s production = 30 million tonnes, consumption = 19 million tonnes. This means a surplus of 11 million tonnes. However, there is only an increase of 2 million (from 3 to 5 million) in its reserves. This means that the exports = 9 million, which is 30% of 30 million. Hence, option d)

2. Question
1 pointsCategory: Quantitative AptitudeDirections for Questions 15: The following graphs (Figure1 and 2) give the production and consumption od coal in certain countries of the world, as well as their reserves.
Shortfall/exess between production and consumption is met by imports/exports.
If India imports its entire coal shortfall from Norway, what percentage of Norway’s export is not to India? (Assume no change in cal stocks)
Correct
Solutions:
India’s coal import = 3822= 16 million tonnes, Norway’s export= 20 million tonnes, hence % of Norway’s export not to India= (2016)/20*100 = 20%
Incorrect
Solutions:
India’s coal import = 3822= 16 million tonnes, Norway’s export= 20 million tonnes, hence % of Norway’s export not to India= (2016)/20*100 = 20%

Question 3 of 10
3. Question
1 pointsCategory: Quantitative AptitudeDirections for Questions 15: The following graphs (Figure1 and 2) give the production and consumption od coal in certain countries of the world, as well as their reserves.
Shortfall/exess between production and consumption is met by imports/exports.
If US produces 5 % of the world coal production, what is the percentage share of Pakistan?
Correct
Solutions:
Suppose x is the world’s production of coal 5% of x production = 40 i.e. 5x/100=40, therefore, x= 800 million tonnes. Pakistan’s share = 10/800*100= 1.25%Incorrect
Solutions:
Suppose x is the world’s production of coal 5% of x production = 40 i.e. 5x/100=40, therefore, x= 800 million tonnes. Pakistan’s share = 10/800*100= 1.25%

4. Question
1 pointsCategory: Quantitative AptitudeDirections for Questions 15: The following graphs (Figure1 and 2) give the production and consumption od coal in certain countries of the world, as well as their reserves.
Shortfall/exess between production and consumption is met by imports/exports.
Which of the following is true?
I. At the given rate of production, reserves of Senegal would last the longest.
II. If each country produced only to meet its requirement, US reserves would last the longest.
III. Assuming constant stocks, total exports of these countries are 70 million tonnes.Correct
Solutions:
US reserves would last the longest as consumption is low and reserve is highest, total exports of these countries are 70 million tonnes as the only exporting countries are(Senegal, Malaysia, US , Norway)
Incorrect
Solutions:
US reserves would last the longest as consumption is low and reserve is highest, total exports of these countries are 70 million tonnes as the only exporting countries are(Senegal, Malaysia, US , Norway)

Question 5 of 10
5. Question
1 pointsCategory: Quantitative AptitudeDirections for Questions 15: The following graphs (Figure1 and 2) give the production and consumption od coal in certain countries of the world, as well as their reserves.
Shortfall/exess between production and consumption is met by imports/exports.
If the coal production of the given set of countries is met by production within the set, approximately how long the reserves last?(assume that they do not trade with counties other than specified, their requirements are constant and no new reserve are discovered during this time).
Correct
Solutions:
Total consumption (in million tonnes) = 130, total reserves (in million tonnes) = 8100, so the reserves will last for 8100/130 = 62 years. Approximately 60 years.
Incorrect
Solutions:
Total consumption (in million tonnes) = 130, total reserves (in million tonnes) = 8100, so the reserves will last for 8100/130 = 62 years. Approximately 60 years.

Question 6 of 10
6. Question
1 pointsCategory: Quantitative AptitudeDirection for Question 68: In the following question, two statements are numbered as I and II. On solving these statements you get Quantity I and Quantity II respectively. Solve for both the statements individually and mark the correct answer.
Quantity I: A school has only four classes that contains 10, 20, 30, and 40 students respectively. The pass percentage of these classes is 20 %, 30%, 60% and 100% respectively. Find the pass % of the entire school.
Quantity II: A train travels with a speed of 20 m/s in the first 10 minutes, goes 8.5 km in the next 10 minutes, 11 km in the next 10 minutes, 8.5 km in the next 10 minutes and 6 km in the next 10 minutes. What is the average speed of the train in kilometre per hour for the journey described?
Correct
Solutions:
Quantity I – The no. of pass candidates are 2+6+18+40= 66 out of a total of 100. Hence, 66 %, whereas Quantity II Find the total distance in each segment of 10 minutes. You will get total distance= 46 km in 50 min, hence average speed will be 55.2, and therefore Quantity I > Quantity II.Incorrect
Solutions:
Quantity I – The no. of pass candidates are 2+6+18+40= 66 out of a total of 100. Hence, 66 %, whereas Quantity II Find the total distance in each segment of 10 minutes. You will get total distance= 46 km in 50 min, hence average speed will be 55.2, and therefore Quantity I > Quantity II.

7. Question
1 pointsCategory: Quantitative AptitudeDirection for Question 68: In the following question, two statements are numbered as I and II. On solving these statements you get Quantity I and Quantity II respectively. Solve for both the statements individually and mark the correct answer.
Quantity I: A landowner increased the length and the breadth of a rectangular plot by 10% and 20% respectively. Find the percentage change in the cost of the plot assuming land prices are uniform throughout his plot.
Quantity II: The salary of Amit is 30% more than that of Varun. Find by what percentage is the salary of Varun less than that of Amit?
Correct
Solutions:
Quantity I At 10% per annum simple interest, the interest earned over 3 years would be 30% of the capital. Thus, 300 is 30% of the capital which means that the capital is 1000. In 3 years, the compound interest on the same amount would be 331 whereas Quantity II – 600 becomes 720 in 4 years SI, i.e. SI per year = Rs.30 and hence SI is 5%, now 5+2=7, therefore at 7%rate of interest the value of 600 would become 768 in 4 years.(600+ 28% of 600), Hence Quantity I < Quantity II.
Incorrect
Solutions:
Quantity I At 10% per annum simple interest, the interest earned over 3 years would be 30% of the capital. Thus, 300 is 30% of the capital which means that the capital is 1000.

8. Question
1 pointsCategory: Quantitative AptitudeDirection for Question 68: In the following question, two statements are numbered as I and II. On solving these statements you get Quantity I and Quantity II respectively. Solve for both the statements individually and mark the correct answer.
Quantity I: Find the compound interest at the rate if 10% for 3 years on that principal which in 3 years at the rate of 10% per annum gives Rs.300 as simple interest.
Quantity II: A sum of Rs.600 amounts to Rs.720 in 4 years at Simple Interest. What will it amount to if the rate of interest is increased by 2%?
Correct
Solutions:
Quantity I At 10% per annum simple interest, the interest earned over 3 years would be 30% of the capital. Thus, 300 is 30% of the capital which means that the capital is 1000. In 3 years, the compound interest on the same amount would be 331 whereas Quantity II – 600 becomes 720 in 4 years SI, i.e. SI per year = Rs.30 and hence SI is 5%, now 5+2=7, therefore at 7%rate of interest the value of 600 would become 768 in 4 years.(600+ 28% of 600), Hence Quantity I < Quantity II.

Correct
Solutions:
Mixing Rs.4/kg and Rs.5/kg to get Rs.4.60/kg we get the ratio of mixing as 2:3. If first oil is 40 kg, the second would be 60kg.Incorrect
