Quantitative Analysis

1. Find a positive number which when increased by 16 is equal to 80 times the reciprocal of the number.
   1. 20
   2. -4
   3. -10
   4. 4

   Answer:

   
   4
   

   Explanation:

   Let the number be x.

   Then x + 16 = 80 * (1/x)

   x² + 16x – 80 = 0
   x² + 20x – 4x – 80 =0
   (x + 20) (x -4)
   Therefore x = 4

2. The LCM. of two numbers is 30 and their HCF. is 15. If one of the numbers is 30, then what is the other number?
   1. 30
   2. 25
   3. 15
   4. 20

   Answer:

   
   15
   

   Explanation:

   Say another number = x

   Product of two numbers = product of HCF and LCM
   => x.30 = 15*30
   => x=15

3. Which of the following is the largest of all ?
   1. 7/8
   2. 15/16
   3. 23/24
   4. 31/32

   Answer:

   
   31/32
   

   Explanation:

   LCM (8, 16, 24, 32) = 96
   7/8 = 84/96
   15/16 = 90/96
   23/24 = 92/96
   31/32 = 93/96
   Hence, 31/32 is the largest of all.

4. Three friends A, B and C are employed to make pastries in a bakery. Working individually, they can make 60, 30 and 40 pastries respectively in an hour. They decided to work together but due to lack of resources, they had to work on shifts of 30 minutes. Find the time taken to make 185 pastries.
   1. 4 hours
   2. 3 hours 45 minutes
   3. 4 hours 15 minutes
   4. 5 hours

   Answer:

   
   4 hours 15 minutes
   

   Explanation:

   It is given that A, B and C make 60, 30 and 40 pastries respectively in an hour.
   => In 30 minutes, they will make 30, 15 and 20 pastries respectively.
   So, in one cycle of 1 hour 30 minutes where each works for 30 minutes, pastries made = 30 + 15 + 20 = 65
   Now, in 2 cycles (3 hours), 130 pastries would be made.
   In the next 30 minutes, A would make 30 pastries.
   So, total time elapsed = 3 hours 30 minutes and pastries made = 130 + 30 = 160
   In the next 30 minutes, B would make 15 pastries.
   So, total time elapsed = 4 hours and pastries made = 160 + 15 = 175
   In the next 15 minutes, C would make 10 pastries.
   So, total time elapsed = 4 hours 15 minutes and pastries made = 175 + 10 = 185
   Therefore, total time taken = 4 hours 15 minutes

5. Three pipes A, B and C were opened to fill a cistern. Working alone, A, B and C require 12, 15 and 20 minutes respectively. Another pipe D, which is a waste pipe, can empty the filled tank in 30 minutes working alone. What is the total time (in minutes) taken to fill the cistern if all the pipes are simultaneously opened ?
   1. 5
   2. 6
   3. 7
   4. 8

   Answer:

   
   6
   

   Explanation:

   Let the capacity of the cistern be LCM(12, 15, 20, 30) = 60 units.
   => Efficiency of pipe A = 60 / 12 = 5 units / minute
   => Efficiency of pipe B = 60 / 15 = 4 units / minute
   => Efficiency of pipe C = 60 / 20 = 3 units / minute
   => Efficiency of pipe D = 60 / 30 = 2 units / minute
   => Combined efficiency of pipe A, pipe B, pipe C and pipe D = 10 units / minute
   
   Therefore, time required to fill the cistern if all the pipes are opened simultaneously = 60 / 10 = 6 minutes

6. The ratio of the speed of two trains is 7:8. If the second train covers 400 km in 4 h, find out the speed of the first train.
   1. 69.4 km/h
   2. 78.6 km/h
   3. 87.5 km/h
   4. 40.5 km/h

   Answer:

   
   87.5 km/h
   

   Explanation:

   Let the speed of the two trains be 7x and 8x.
   Then, 8x = 400 / 4
   => 8x = 100 => x = 12.5 km/h.
   Hence, speed of the first train = 7x = 7 × 12.5 = 87.5 km/h.

7. A motorboat crosses a certain distance in 1 hour and comes back in 1½ hours. If the stream is running at 3 km/h, find out the speed of motorboat in still water.
   1. 10 km/h
   2. 15 km/h
   3. 12 km/h
   4. None of these

   Answer:

   
   15 km/h
   

   Explanation:

   Let the speed of motorboat in still water be x km/h. Then,
   Downstream speed = (x + 3) km/h.
   Upstream speed = (x – 3) km/h.
   Then, (x + 3) × 1 = (x – 3) × 3/2
   => 2x + 6 = 3x – 9
   => x = 15.
   So, the speed of motorboat in still water is 15 km/h.

8. Barack spends Rs 6650 to buy some goods and gets a rebate of 6% on it. After this, he pays a sales tax of 10%. What is his total expenditure?
   1. Rs 6870.10
   2. Rs 6876.10
   3. Rs 6865.10
   4. Rs 6776.10

   Answer:

   
   Rs 6876.10
   

   Explanation:

   Rebate received by Barack = 6% of Rs 6650 = 6/100 × 6650 = 3/5 × 665 = Rs 399.
   Sales Tax paid by Barack = 10% of Rs (6650-399) = 10% of Rs 6251 = Rs 625.10.
   Therefore, Barack’s total expenditure = Rs (6251 + 625.10) = Rs 6876.10.

9. In a box, there are 10p, 25p and 50p coins in the ratio 4:9:5 with the total sum of Rs 206. How many coins of each kind does the box have?
   1. 200, 360, 160
   2. 135, 250, 150
   3. 90, 60, 110
   4. Cannot be determined

   Answer:

   
   200, 360, 160
   

   Explanation:

   Let the number of 10p, 25p, 50p coins be 4x, 9x, 5x respectively. Then,
   4x/10 + 9x/4 + 5x/2 = 206 (Since, 10p = Rs 0.1, 25p = Rs 0.25, 50p = Rs 0.5)
   => 8x + 45x + 50x = 4120 (Multiplying both sides by 20 which is the LCM of 10, 4, 2)
   => 103x = 4120
   => x = 40.
   Therefore,
   No. of 10p coins = 4 x 40 = 160 (= Rs 16)
   No. of 25p coins = 9 x 40 = 360 (= Rs 90)
   No. of 50p coins = 5 x 40 = 200 (= Rs 100)

10. At present, the ratio between ages of Ram and Shyam is 6:5 respectively. After 7 years, Shyam’s age will be 32 years. What is the present age of Ram?
    1. 32
    2. 40
    3. 30
    4. 36

    Answer:

    
    30
    

    Explanation:

    Let the present age of Ram and Shyam be 6x years and 5x years respectively.

    Then 5x + 7 = 32
    => 5x = 25
    => x = 5
    => Present age of Ram = 6x = 30 years

Verbal Reasoning

1. While trying to collect(I) an envelope from under the table (II), Mr. X fell down (III) and was losing consciousness (IV)

   Which one of the above underlined parts of the sentence is NOT appropriate?

   1. I
   2. II
   3. III
   4. IV

   Answer:

   
   IV
   

   Explanation:

   Here, part IV is incorrect. “was losing consciousness” shows the continuous process of losing consciousness, but he was not in the process, rather he just lost consciousness.
   So, the correction is ” was losing consciousness ”  => ” lost consciousness “.

   Thus, IV is the correct choice.

2. If she _______________ how to calibrate the instrument, she _______________ done the experiment.
   1. knows, will have
   2. knew, had
   3. had known, could have
   4. should have known, would have

   Answer:

   
   had known, could have
   

   Explanation:

   A)knows, will have //Present, future

   B)knew, had //past past

   c)had known, could have//past perfect, perfect conditional

   D)should have known, would have //present, future

   In a Type 3 conditional sentence, the tense in the ‘if’ clause is the past perfect, and the tense in the main clause is the perfect conditional or the perfect continuous conditional.

   If clause (condition)	Main clause (result)
   If + past perfect	perfect conditional or perfect continuous conditional
   If this thing had happened	that thing would have happened.

3. Choose the word that is opposite in meaning to the word “coherent”.
   1. sticky
   2. well-connected
   3. rambling

   Explanation:

   Coherent – Adj.
   Meaning – (of an argument, theory, or policy) logical and consistent.

   Rambling – Adj.
   Meaning – (of writing or speech) lengthy and confused or inconsequential.

   Hence both are opposite to each other.
