14620.If the sum of three consecutive even numbers is 44 more than the average of these numbers, then the largest of these numbers is?
20
24
22
None of these
Explanation:

Let the smallest of these number be x. The other two numbers are (x + 2) and (x + 4).

=> x + (x + 2) + (x + 4) = (X + (X+2) + (x+4)) / 3 + 44

=> 3x + 3 $\times$ (x + 2) + 3 $\times$ (x + 4) = x + (x + 2) + (x + 4) + 132

=> 9x + 18 = 3x + 138

=> 6x = 120

=> x = 20

Therefore, the largest number is 24.

14621.Two trains 140 meters and 120 meters are running in the same direction with speeds 40 kmph and 60 kmph respectively. In what time will the faster train pass the slower one?
0.60 minutes
0.36 minutes
0.78 minutes
0.42 minutes
Explanation:

Total distance = addition of length of the two trains = 140 + 120 = 260 meters

As the two trains are travelling in the same direction, their relative speed is:

=> v = | v1 - v2 | = | 40 - 60 | = 20 km/hr. = 20 $\times$ 1000/60 = 1000/3 meters/min

=> t = 260/ 1000 $\times$ 3

=> t = 0.78 minutes

14622.When a student weighing 45 kgs left a class, the average weight of the remaining 59 students increased by 200g. What is the average weight of the remaining 59 students?
55
56
57
58
Explanation:

Let the average weight of the 59 students be A.

So, the total weight of the 59 of them will be 59 $\times$ A.

Given that when the weight of this student who left is added, the total weight of the class = 59A + 45

When this student is also included, the average weight decreases by 0.2 kgs.

So,

=> (59A+45)/60 = A-0.2.

=> 59A + 45 = 60A - 12.

=> 45 + 12 = 60A - 59A.

=> A = 57.

14623.A and B go cycling in the same direction with speeds of 6 km/hr. and 12 km/hr. A car from behind passes them in 9 and 10 seconds respectively. What is the speed of the car?
22 km/hr.
33 km/hr.
66 km/hr.
44 km/hr.
Explanation:

The relative speed of A and B is 6 km/hr. = 1.67 m/s

As the car passes A after 10s, the distance between A and B after 10s (i.e. at 11th second) is the distance covered by car in 1 second.

Therefore, at t = 11, d = 1.67 $\times$ 11

d = 18.33 m

v = d/t = 18.33/1 = 18.33m/s

v = 66 km/hr.

14624.A sum of Rs. 4000 amounts to Rs. 4600 in 5 years at a certain rate of simple interest. What would be the amount, if the rate of interest is increased by 3 %?
Rs. 4900
Rs. 5000
Rs. 5200
Rs. 5600
Explanation:

Given,

Principal = Rs. 4000, Amount = Principal + SI = Rs. 4600

SI = Amount - Principal = 4600 - 4000 = Rs. 600

Time = T = 5 years and SI = Rs. 600

Since, SI =PRT/100

=> 600 = 4000 $\times$ R $\times$ 5/100

=> 600 = 200R

=> R = 3 % p.a.

Now the new interest rate is = 3% + 3% = 6 % p.a.

=> SI = PRT/ 100 = 4000 $\times$ 6 $\times$ 5/ 100 = Rs. 1200

Hence the required amount = Principal + SI

= 4000 + 1200 = 5200.

14625.For a candidate to clear an examination, he/she must score 55% marks. If he/she gets 120 and fails by 78 marks, the total marks for the examination is
300
360
400
320
Explanation:

Here the mark obtained by the candidate is 120 and the candidate fails by 78 marks.

Therefore the passing marks is (120+78) = 198

Let the total marks be x. Then,

=> 55/100 $\times$ x = 198

=> x = 360.

14626.A man on tour travels first 160 km at 64 km/hr. and the next 160 km at 80 km/hr. The average speed for the first 320 km of the tour is:
35.55 km/hr.
36 km/hr.
71.11 km/hr.
71 km/hr.
Explanation:

Total time taken = (160/64 + 160/80) hrs. = 9/2 hrs.

$\therefore$ Average speed = (320 x 2/9) km/hr. = 71.11 km/hr.

14627.Shyam can do a job in 20 days, Ram in 30 days and Singhal in 60 days. If Shyam is helped by Ram and Singhal every 3rd day, how many days will it take for them to complete the job?
12
16
15
10
Explanation:

As Shyam is helped by Ram and Singhal every third day, Shyam works for 3 days while Ram and Singhal work for 1 day in every 3 days.

Therefore, the amount of work done in 3 days by Shyam, Ram and Singhal:

=> 3/20 + 1/30 + 1/60

=> 1/5 of the job.

Hence, it will take them 5 times the amount of time = 3 $\times$ 5 = 15 days.

14628.A trader has 200 kg of sugar, out of which he sells some with 10% profit and the rest with 25% profit. He gains 15% on the whole. Find the quantity of sugar sold at 25% profit?
120 kg
96.5 kg
84 kg
67 kg
Explanation:

Let CP of each kg. of sugar = Rs.1.

Cost Price of 200 kg of sugar = Rs.200.

Let quantity of sugar sold with 25% profit be X.

Therefore, (200 - X) kg of sugar sold at a profit of 10%

Then,

=> (125/100 $\times$ X) + 110/100 (200 - X) = 115/100 $\times$ 200

=> 125X + 110(200 - X) = 115 $\times$ 200

=> 125X + 22000 - 110X = 23000

=> 125X - 110X = 23000 - 22000

=> 15X = 1000

=> X = 1000/15

=> X = 66.66 kg =67(approx.)

14629.P, Q, R subscribe Rs. 50,000 for a business. P subscribes Rs. 4000 more than Q and Q Rs. 5000 more than R. Out of a total profit of Rs. 25,000, what will be Ps share?
Rs. 8400
Rs. 10,500
Rs. 13,600
Rs. 14,700
Explanation:

Let amount subscribed for R be x.

Therefore, Q = x + 5000 and P = x + 5000 + 4000 = x + 9000

So, x + x + 5000 + x + 9000 = 50000

=> 3x = 36000

=> x = 12000

=> P: Q: R = 21000: 17000: 12000 = 21: 17: 12

Hence, P`s share = 25000 X (21/50) = Rs. 10,500.

14630.Nehas mother was four times her age 12 years ago. She will be twice as old as Neha 12 years from now. What is the present age of Nehas mother?
49 years
57 years
60 years
65 years
Explanation:

Let Nehas present age be x years.

Her age 12 years ago = (x - 12) years

Therefore, her mothers age 12 years ago = 4(x - 12)

Her mothers present age = 4x - 48 + 12 = 4x - 36

Nehas age after 12 years = x + 12

Her mothers age after 12 years = 4x - 36 + 12 = 4x - 24

=> 4x - 24 = 2(x + 12)

=> 4x - 2x = 24 + 24

=> x = 24

Therefore, Nehas present age = 24

Hence, Her mothers present age = 4x - 36 = 4(24) - 36 = 60 years.

14631.Two trains running in opposite directions cross a man standing on the platform in 27 seconds and 17 seconds respectively. If they cross each other in 23 seconds, what is the ratio of their speeds?
Insufficient data
3: 1
1: 3
3: 2
Explanation:

Let the speed of the trains be x and y respectively

length of train1 = 27x

length of train2 = 17y

Relative speed= x + y

Time taken to cross each other = 23 s

=> (27x + 17 y)/(x+y) = 23

=> (27x + 17 y)/ = 23(x+y)

=> 4x = 6y

=> x/y = 6/4 = 3/2.

14632.Cisco Verbal Ability Test

It is time, we looked at the latent causes. Where does the strength of India lie? Not in numbers, not necessarily in our moral stands on international issues. In modern times, the strength of a nation lies in its achievements in science and technology. This is not to say that other fields do not count.

In the five decades after independence, we have yet to demonstrate our originality in applied science and technology. Though Japan also started like us, yet by cultivating the technology of the West, the Japanese adapted, improved and displayed originality in several areas of science and technology. The generationwhich is at the helm of affairs in science and in our country after independence mostly consisted of self-seekers. By and large with a few exceptions. The science and technology managers in India concentrated in gaining power and influence.

They loved publicity. Most of them stopped doing science while they managed science. Things would have been better had they been humble enough to acknowledge the difference between doing and managing science. Instead they claimed they were the foremost in science and technology, simply because theywere at the helm of affairs. As a result, they ceased to inspire the younger lot. India continues to be a borrower of science and technology, even though its potential for originality is substantial.

Our achievements in nuclear science and technology may be dazzling to our people. But, in worth and originality, they are ordinary and routine. While our own people remain ignorant the people of other countries know all about the pretensions to knowledge of our nuclear science and technology managers. Our subtle way of sabotaging our nuclear goals is to help hollow persons reach and remain at the helm of affairs. International bodies come in as handy tools in that subtle process. The veil of secrecy effectively protects the mismanagement in our nuclear establishments. The talk of national security comes as an easy weapon to prevent any probe into mismanagement. On nuclear matters the media in our country, by and large avoid the mismatch between promise and hence performance in the nuclear field does not get exposed as much as the mismanagement in other fields.

What does the author mean by `doing` science?
