Your answers are highlighted below.

Question 1 |

A can do a piece of work in 4 hours. A and C together can do it in just 2 hours, while B and C together need 3 hours to finish the same work. B alone can complete the work in how many hours?

A | 12 hours |

B | 6 hours |

C | 8 hours |

D | 10 hours |

Question 1 Explanation:

Work done by A in 1 hour = 1/4

Work done by B and C in 1 hour = 1/3

Work done by A and C in 1 hour = 1/2

Work done by A,B and C in 1 hour = 1/4 + 1/3 = 7/12

Work done by B in 1 hour = 7/12 – 1/2 = 1/12

=> B alone can complete the work in 12 hours

Work done by B and C in 1 hour = 1/3

Work done by A and C in 1 hour = 1/2

Work done by A,B and C in 1 hour = 1/4 + 1/3 = 7/12

Work done by B in 1 hour = 7/12 – 1/2 = 1/12

=> B alone can complete the work in 12 hours

A | 16 yrs |

B | 18 yrs |

C | 28 yrs |

D | 24.5 yrs |

Question 4 Explanation:

S = R - 7

S:R = 7:9

9S = 7R

9(R-7) = 7R

2R = 63

R = 31.5

S = 24.5

S:R = 7:9

9S = 7R

9(R-7) = 7R

2R = 63

R = 31.5

S = 24.5

Question 5 |

A | 100 cm |

B | 50 cm |

C | 25 cm |

D | 20 cm |

Question 5 Explanation:

Question 9 |

A vessel contains 20 liters of a mixture of milk and water in the ratio 3:2. 10 liters of the mixture are removed and replaced with an equal quantity of pure milk. If the process is repeated once more, find the ratio of milk and water in the final mixture obtained?

A | 9 : 1 |

B | 4 : 7 |

C | 7 : 1 |

D | 2 : 5 |

Question 9 Explanation:

Milk = 3/5 * 20 = 12 liters, water = 8 liters

If 10 liters of mixture are removed, amount of milk removed = 6 liters and amount of water removed = 4 liters

Remaining milk = 12 - 6 = 6 liters

Remaining water = 8 - 4 = 4 liters

10 liters of pure milk are added, therefore total milk = (6 + 10) = 16 liters

The ratio of milk and water in the new mixture = 16:4 = 4:1

If the process is repeated one more time and 10 liters of the mixture are removed, then amount of milk removed = 4/5 * 10 = 8 liters

Amount of water removed = 2 liters

Remaining milk = (16 - 8) = 8 liters

Remaining water = (4 -2) = 2 liters

The required ratio of milk and water in the final mixture obtained = (8 + 10):2 = 18:2 = 9:1

If 10 liters of mixture are removed, amount of milk removed = 6 liters and amount of water removed = 4 liters

Remaining milk = 12 - 6 = 6 liters

Remaining water = 8 - 4 = 4 liters

10 liters of pure milk are added, therefore total milk = (6 + 10) = 16 liters

The ratio of milk and water in the new mixture = 16:4 = 4:1

If the process is repeated one more time and 10 liters of the mixture are removed, then amount of milk removed = 4/5 * 10 = 8 liters

Amount of water removed = 2 liters

Remaining milk = (16 - 8) = 8 liters

Remaining water = (4 -2) = 2 liters

The required ratio of milk and water in the final mixture obtained = (8 + 10):2 = 18:2 = 9:1

Question 10 |

A train 360 m long is running at a speed of 45 km/hr. In what time will it pass a bridge 140 m long?

A | 40 sec |

B | 42 sec |

C | 45 sec |

D | 48 sec |

Question 10 Explanation:

Formula for converting from km/hr to m/s: Xkm/hr = (X * 5 / 18) m/sec

Therefore, Speed = (45 * 5 /18) m/sec

= 25/2 m/sec

Total distance to be covered = (360 + 140) m = 500 m

Formula for finding Time = (Distance / Speed)

Required time = (500 x 2 / 25)sec = 40 sec

Therefore, Speed = (45 * 5 /18) m/sec

= 25/2 m/sec

Total distance to be covered = (360 + 140) m = 500 m

Formula for finding Time = (Distance / Speed)

Required time = (500 x 2 / 25)sec = 40 sec

Question 11 |

217 x 217 + 183 x 183 = ?

A | 79698 |

B | 80578 |

C | 80698 |

D | 81268 |

Question 11 Explanation:

(217)

= 2 x [(200)

= 2[40000 + 289]

= 2 x 40289

= 80578

^{2 }+(183)^{2 }= (200 + 17)^{2}+ (200 - 17)^{2}= 2 x [(200)

^{2}+ (17)^{2}] [**Ref:**(a + b)^{2}+ (a - b)^{2}= 2(a^{2}+ b^{2})]= 2[40000 + 289]

= 2 x 40289

= 80578

Question 12 |

A, B and C jointly thought of engaging themselves in a business venture. It was agreed that A would invest Rs.6500 for 6 months, B Rs.8400 for 5 months and C, Rs. 10,000 for 3 months. A is the only working partner and hence gets 8% of the profits. The profit earned was Rs. 7400. Calculate the share of B in the profit?

A | Rs. 2800 |

B | Rs. 1400 |

C | Rs. 3700 |

D | Rs. 2576 |

Question 12 Explanation:

A: B: C = (6500*6) : (8400*5) : (10000*3)

= 13: 14:10

8% goes to A

Of the remaining 92%, B’s share = 0.92*7400*14/37 = Rs. 2576

= 13: 14:10

8% goes to A

Of the remaining 92%, B’s share = 0.92*7400*14/37 = Rs. 2576

Question 13 |

A group of 50 students were required to clear 2 tasks, one in rock-climbing and the other in bridge crossing during an adventure sports expedition. 30 students cleared both the tasks. 37 cleared bridge crossing, 38 student cleared rock-climbing. How many students could not clear any task?

A | 4 |

B | 5 |

C | 9 |

D | 10 |

Question 13 Explanation:

No. of student those completed at least one task: 37 + 38 - 30 = 45

No. of students those did not complete any task: 50 - 45 = 5

No. of students those did not complete any task: 50 - 45 = 5

Question 14 |

0.002 x 0.5 = ?

A | 0.0001 |

B | 0.001 |

C | 0.01 |

D | 0.1 |

Question 14 Explanation:

2 x 5 = 10

Sum of decimal places = 4

0.002 x 0.5 = 0.001

Sum of decimal places = 4

0.002 x 0.5 = 0.001

Question 15 |

A tank has three inlets A,B and C. C takes twice the time taken by A to fill the tank and B takes half the time taken by A to fill the tank. If they can fill the tank together in 4 minutes, find the time taken by B to fill the tank?

A | 7 minutes |

B | 14 minutes |

C | 3.5 minutes |

D | 28 minutes |

Question 15 Explanation:

Let A take x minutes to fill the tank (1/x) + (1/ (x/2)) + (1/2x) = 1/4

(7/2x) = ¼

x=14

x /2 = 7

(7/2x) = ¼

x=14

x /2 = 7

Question 16 |

The price of an article has been reduced by 25%. In order to restore the original price the reduced price must be increased by?

A | 25% |

B | 30% |

C | 33% |

D | 33.1/3% |

Question 16 Explanation:

Reduced price = (100 - 75) = 25%

Original price = 25/75 * 100 = 33.1/3%

Original price = 25/75 * 100 = 33.1/3%

Question 17 |

= 10P4.

= (10 x 9 x 8 x 7).

= 5040.

Required number of words = Number of arrangements of 10 letters, taking 4 at a time..

= 10P4.

Question 20 |

Two tailors X and Y are paid a total of Rs. 550 per week by their employer. If X is paid 120 percent of the sum paid to Y, how much is Y paid per week?

A | Rs. 200 |

B | Rs. 250 |

C | Rs. 300 |

D | None of these |

Question 20 Explanation:

Let the sum paid to Y per week be Rs. z.

Then, z + 120% of z = 550.

z + (120/100 )z = 550

(11/5)z = 550>br/> z = (550 x 5) 11 = 250.

Then, z + 120% of z = 550.

z + (120/100 )z = 550

(11/5)z = 550>br/> z = (550 x 5) 11 = 250.

Question 21 |

Find the cost of Rs.6400, 10% stock at 15 discount

A | 5440 |

B | 5480 |

C | 6440 |

D | 6480 |

Question 21 Explanation:

Cost of Rs. 100 stock = Rs. (100 - 15)
Cost of Rs. 6400 stock = Rs. (85/100 * 6400) = Rs. 5440

Question 22 |

Find the present worth of Rs.78000 due in 4 years at 5% interest per year

A | Rs. 65000 |

B | Rs. 63000 |

C | Rs. 67000 |

D | Rs. 61000 |

Question 22 Explanation:

Amount with interest after 4 years = Rs. 78000

Therefore, simple interest = 78000 – Principal

Let the principal amount be p

78000 – p = p * 4 * 5 / 100

p = 13000

Principal = 78000 – 13000 = Rs. 65000

Therefore, simple interest = 78000 – Principal

Let the principal amount be p

78000 – p = p * 4 * 5 / 100

p = 13000

Principal = 78000 – 13000 = Rs. 65000

Question 23 |

A | 25 |

B | 16 |

C | 20 |

D | 12 |

Question 23 Explanation:

A | Only 1 |

B | Only 2 |

C | Either 1 or 2 |

D | 1 and 2 both |

Question 25 Explanation:

M is the father of N and N is the son of V.
Hence, V is the mother of N.
From (1), P is the brother of V
Therefore, M is the brother-in-law of P because V is the wife of M.

From (2), the daughter of N, is the granddaughter of V.

From this we do not get any relation of M to P.

From (2), the daughter of N, is the granddaughter of V.

From this we do not get any relation of M to P.
