Question 1 of 10
1. Question
1 pointsCategory: Quantitative AptitudeDirections for questions (15): Refer to thae data givent below and table to answer the questions that follow.
Praveen Kumar has a factory which manufactures Kryptonite, Arsonite, and Liptonite. All these are manufactured by processing Ramena 55. Kryptonite requires 2 kg/unit, Arsonite requires 4 kg/unit, and liptonite requires 5 kg/unit of Ramena 55, which costs Rs. 4 per kilogram. The total availability of Ramena 55 is 700 kilograms. The processing is done on a machine having a production capacityof 324 hours per month in the day shift and 364 hours per month in the night shift. The time required per unit production for each product is different for each shift and is as follows:
What percentage of the available raw materials is utilised if 100 units of Kryptonite, 40 units of Arsonite, and 10 units of Liptonite are produced?
Correct
Solution: Total raw materials available = 700 kg. Raw material required for production of 100 unit of Kryptonite = 100*2 = 200 kg, For 40 units of Arsonite = 40*4 = 160 kg, For 10 units of Liptonite = 10*5 = 50 kg. Total raw material utilised is = 200+ 160+ 50 = 410 kg. Therefore percentage raw material utilised = 410/700*100~ 58%
Incorrect
Solution: Total raw materials available = 700 kg. Raw material required for production of 100 unit of Kryptonite = 100*2 = 200 kg, For 40 units of Arsonite = 40*4 = 160 kg, For 10 units of Liptonite = 10*5 = 50 kg. Total raw material utilised is = 200+ 160+ 50 = 410 kg. Therefore percentage raw material utilised = 410/700*100~ 58%

Kryptonite requires 2 kg/unit, Arsonite requires 4 kg/unit, and liptonite requires 5 kg/unit of Ramena 55, which costs Rs. 4 per kilogram. The total availability of Ramena 55 is 700 kilograms. The processing is done on a machine having a production capacityof 324 hours per month in the day shift and 364 hours per month in the night shift. The time required per unit production for each product is different for each shift and is as follows:
If Praveen Kumar spends initially 300 machine hours in the day shift to maufacture Liptonite, 20 hours to manufacture Kryptonite, and in the night shift manufactures 53 units of Liptonite and spends the rest of the night shift to manufacture Kryptonite. What will be the profit/loss?
Correct
Solution: Time taken in day shift to produce a unit of liptonite = 2 hour, there fore unite of liptonite produced = 300/2 = 150 units. Time taken in the day shift to manufacture kryptonite = 4 hours, then units of Kryptonite produced = 20/4 = 5 units. Again, in night shift53 units of liptonite are produced, Since it is given in the question that at the most 150 units of Liptonite can be produced, Hence this manufacturing pattern is not possible.
Incorrect
Solution: Time taken in day shift to produce a unit of liptonite = 2 hour, there fore unite of liptonite produced = 300/2 = 150 units. Time taken in the day shift to manufacture kryptonite = 4 hours, then units of Kryptonite produced = 20/4 = 5 units.

The time required per unit production for each product is different for each shift and is as follows:
If the minimum possible manufacturing requirement for Kryptonite is met and remaining remaining raw material is utilised for the manufacture of the other 2 products then
Correct
Solution: Minimum possible manufactiring requirement for Kyptonite is 50 units , hence raw material used is 2*50 = 700 kg. Raw material for the remaining 2 products is 600 kg. So, any of the above production is possible.

The time required per unit production for each product is different for each shift and is as follows:
Which of the following is possible?
Correct
Solution: In day shift, 74 units of Kryptonite and 4 units of Arsonite will take 74*4 + 4*6 = 320 hour which is within the limit. Also in night shift 2 units of Arsonite, 10 units of Liptonite and 30 units of Kryptonite will take = 8*20 + 10*3 + 30*5 = 340 hours, which is again well below the limit. Hence c is correct.
Incorrect

Also in night shift 2 units of Arsonite, 10 units of Liptonite and 30 units of Kryptonite will take = 8*20 + 10*3 + 30*5 = 340 hours, which is again well below the limit. Hence c is correct.

Question 6 of 10
6. Question
1 pointsCategory: Quantitative AptitudeDirection for Question 67: 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: The average weight of 6 persons is increased by 2.5 kg when one of them whose weight is 50 kg is replaced by a new man. The weight of the new man is?
Quantity II: The average weight of 6 men is 68.5 kg. If it is known that Ram and Tram weigh 60 kg each, what is the average weight of others?Correct
Solution: Quantity I: The total weight of the six people goes up by 15 kgs(when the average of 6 persons go up by 2.5kg). Thus, the new person must be 15 kgs more than the person who he replaces. Hence, the new person’s weight = 50+15 = 65 kg. Quantity II: Total weight of all 6 = 68.5*6. Total weight of Ram and Tram = 60*2 =120. Average weight of the four people excluding Ram and Tram = (68.5*6 – 120)/4= 72.75 kg. Hence, Quantity I < Quantity II
Incorrect
Solution: Quantity I: The total weight of the six people goes up by 15 kgs(when the average of 6 persons go up by 2.5kg). Thus, the new person must be 15 kgs more than the person who he replaces. Hence, the new person’s weight = 50+15 = 65 kg. Quantity II: Total weight of all 6 = 68.5*6. Total weight of Ram and Tram = 60*2 =120. Average weight of the four people excluding Ram and Tram = (68.5*6 – 120)/4= 72.75 kg. Hence, Quantity I < Quantity II

Question 7 of 10
7. Question
1 pointsCategory: Quantitative AptitudeDirection for Question 67: 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 sum of money invested at simple interest triples itself in 8 years at simple interest. Find in how many years will it become 8 times itself at the same rate?
Quantity II: A sum of money doubles itself in 5 years. In how many years will it become four times (if interest is compounded)?Correct
Solution: Quantity I: In 8 years, the interest earned = 200%, thus, per year interest rate = 200/8 = 25%. To become 8 times we need a 700% increase, 700/25 = 28 years. Quantity II: It would take another 5 years to double again. Thus, a total of 10 years to become four fold. Hence, Quantity I > Quantity II
Incorrect
Solution: Quantity I: In 8 years, the interest earned = 200%, thus, per year interest rate = 200/8 = 25%. To become 8 times we need a 700% increase, 700/25 = 28 years. Quantity II: It would take another 5 years to double again. Thus, a total of 10 years to become four fold. Hence, Quantity I > Quantity II

1 pointsCategory: Quantitative AptitudeDirections for Questions 810: Read the following passage and answer the questions based on it.
The Bangalore office of Infosys has 1200 executives. Of these, 880 subscribe to the Time magazine and 650 subscribe to the Economist. Each executive may subscribe to either the Time of the Economist or both. If an executive is picked at random, answer the following questions:What is the probability that he has subscribed to the Time magazine
Correct
Solution: Time magazine subscription = 880, Economist subscription = 650 and Both subscription = 1530 – 1200 = 330. Hence Probability of Time magazine = 880/1200 = 11/15
Incorrect
Solution: Time magazine subscription = 880, Economist subscription = 650 and Both subscription = 1530 – 1200 = 330. Hence Probability of Time magazine = 880/1200 = 11/15

What is the probability that he has also subscribed to the Economist?
Correct
Solution: Time magazine subscription = 880, Economist subscription = 650 and Both subscription = 1530 – 1200 = 330. Hence probability of both among Time magazine = 330/880 = 3/8
Incorrect
Solution: Time magazine subscription = 880, Economist subscription = 650 and Both subscription = 1530 – 1200 = 330. Hence probability of both among Time magazine = 330/880 = 3/8
