Explanation:

Solution is
Given 12.99 - 3.01 + ( ( 12.01 / 3.99 ) * 5.01 )
= 13 - 3 + [ ( 12 / 4 ) * 5 ]
= 13 - 3 + ( 3 * 5 )
= 13 - 3 + 15
= 25
Answer is 25

Read the following passage carefully and answer the questions given below. Certain words/phrases have been printed in bold to help you locate them.

The recurrence of a major earthquake on May 12 — this time measuring 7.3 on the Richter scale — with its epicentre near Kodari in Nepal, barely a fortnight after the devastating temblor in the landlocked country, has once again raised questions about preparedness for such disasters in the subcontinent. India is divided into five seismic zones, with Zone 5 being the most active and earthquake-prone. The Himalayan regions, the Assam and Burma region, and the Bhuj region in the west fall in this category. While the time of occurrence of a big earthquake cannot be predicted accurately with existing technology, the foreknowledge of potential danger areas can help mitigate the impact of a disaster. The reason for earthquakes occurring in Nepal is knvvown: the movement of the Indian tectonic plate against the Eurasian plate. Along the Himalayas lie two fault-lines: the Main Boundary Thrust and the Main Central Thrust. Running parallel to the Himalayan ranges to a width of 100 km to 120 km, this region has a history of earthquakes. In the last 120 years, there have been four major events: 1897 (Shillong), 1905 (Himachal Pradesh, Kangra), 1934 (Nepal-Bihar border), 1950 (Arunachal Pradesh, then a part of the North East Frontier Agency or NEFA).

The movement of the Indian tectonic plate against the Eurasian plate has created accumulated stress. This stress is released in a manner that makes predicting earthquakes impossible. When a major event happens, part of the stress is released at that point but accumulates in a different part of the belt. Thus there is no natural escape for the region from susceptibility to earthquakes. The best-laid plans for disaster mitigation following quakes can go awry, but some lessons can be learnt from the past. However, as the gap between the occurrence of major earthquakes in a given region could stretch over more than a lifespan, memories can fade and mitigation plans may not be grounded in lived experience. The real advancement that has been made recently in India is, for instance, the setting up of many seismological stations, especially after the Bhuj earthquake of 2001. Measurements from these stations and global positioning system data now tell us the Indian plate is moving north at a speed of 5 metres a year. This would contribute to stress accumulation and to seismic activity even in Zones 2, 3 and 4. We need to accept earthquakes as a reality and do everything in our power to redefine development plans, especially in terms of building quake-resistant buildings. There should be systematic resort to “disaster drills” to educate the public on what to do during an earthquake. Preparedness is the key to managing any more such disasters.

5. Two trains are travelling opposite to each other at a speed of 120 kmph and 80 kmph, if the distance between them is 400 km, at 3:30pm, at what time the two trains will collide each other?



Explanation:

Solution is
Given

speed=120kmph and 80 kmph
distance=400 km
time=3:30 pm
Relative speed = 120 + 80 = 200kmph
Distance = 400 km
Time = distance / speed = 400/200 = 2 hrs
At 5:30 pm, the collision will take place
Answer is 5:30PM

7. Find the value of 0.24x0.24 + 3.24x3.24 - 2x0.7776 = ?



Explanation:

Solution is
Given 0.24x0.24 + 3.24x3.24 - 2 x 0.7776
Formula reference : a2 + b2 - 2 x a x b = ( a - b )2
= ( 0.24 )2+( 3.24 )2 - 2 x ( 0.24 ) x ( 3.24 )
= ( 3.24 - 0.24 )2
= ( 3 )2
= 9
Answer is 9


8. A,B,C complete a given work in 12 , 42 and 28 days respectively. If all three of them work together, in how many days the work will get completed ?



Explanation:

Solution is
Given

A's 1 day work = 1/12
B's 1 day work = 1/42
C's 1 day work = 1/28
All three are working together
A+B+C 's1 day work = (1/12) + (1/42) + (1/28)
[L C M of 12 , 42 , 28 = 84]
= (7 + 2 + 3) / 84 = 12 / 84
A+B+C 's 1 day work = 1/7
A+B+C will take 7 days to finish the work
Answer is 7

11. Which of the following menu types is also called a drop-down menu?





12. The marked price of a radio is 40% more than its cost price. If a discount of 10% is given on the marked price, find the gain percent.



Explanation:

Let the C.P = 100 Rs.

M.P = 40% more than 100.

M.P = 140 Rs.

He gives discount of 10%,
S.P = 140 - 14 = 126 Rs

Profit 26 Rs.
=> Profit percentage = 26%

Explanation:

Let the amount of Royalty to be paid for these books be Rs. r. Then, 20 : 15 = 30600 : r => r = Rs. ( 30600 x 15 )/20 = Rs. 22,950.

Explanation:

Given principal = 2500 No. of years = 2 Rate of interest = 10 Amount = P x (1+r/100)^n, we get Amount = 2500 x (1+10/100)^2 Ans : 3025


Refer this table

18. What is the average amount of interest per year which the company had to pay during this period?



Explanation:

Average amount of interest = (23.4 + 32.5 + 41.6 +36.4 + 49.4)/5 = 183.3 / 5 = Rs. 36.66 laks


19. In how many ways a four digit even number can be formed by using the digits 2,3,5,8 exactly once?



Explanation:

Solution is
Given

Four digit even number can be formed by using the digits 2,3,5,8
Since the number has to be an even number,the unit digit has to be 2 or 8.
First three places can be filled by remaining three digits.

= 3! + 3!
= (3*2*1)+(3*2*1)
= 6 + 6 =12
Hence totally 12 ways


20. How many liters of water should be added to a 30 liter mixture containing milk and water in the ratio 7:3 such that the resultant mixture has 40 % water in it



Explanation:

Solution is
Given
In 30 litres of mixture, milk and water ratio is7 : 3
Let m = milk ; w = water
=> m / w = 7 / 3 = 7x liters / 3x litres
=> 7x + 3x =30
=> 10x =30
=> x = 3
m= 7x litres = 21 litres
w= 3x litres = 9 litres
When we add x litres of water the resulting solution contains 21 litres of milk and (9+x) litres of water
Total quantity = 30 + x
Given , percentage of water in this new mixture =40%
i.e 40% of new mixture =water
=> 40/100(30 + x) =9 + x
=> (2/5) (30 + x) = (9 +x)
=> 2(30 + x) = 5 (9 +x)
=> 60 + 2x = 45 + 5x
=> 5x - 2x = 60 - 45 => 3x= 15 => x=5
Answer is 5

24. Find the simple interest on Rs. 7200 at 5 % per annum for 9 months



Explanation:

Solution is
Given
Principal : 7200
Rate of interest : 5
Number of months : 9
Simple Interest for 1 year = (7200 x 1 x 5) / 100
Simple Interest for 1 year = 360
Simple interest is calculated for years,but given time period is in month son = 9 / 12
Simple interest for 9 months = (9/12) x SI =(3/4)x 360
Simple Interest for 9 months = 270
Answer is270


Refer the above piechart

Answer is69.45


27. Two liquids A and B are mixed together in the ratio 2 : 3. The average cost of liquid B is Rs 30 per liter and the average cost of the mixture is Rs. 25 per liter, then find the average cost of liquid A per liter.



Explanation:

Solution is
Given liquids A and B = 2 : 3
Average cost of mixture = Rs. 25 / liter
Average cost of liquid B = Rs. 30 / liter
Let Average cost of liquid A = x per liter

According to the alligation equation,
( 30 - 25 ) / ( 25 - x ) = 2 / 3
=> 5 / ( 25 - x ) = 2 / 3
=> 5 x 3 / 2 = ( 25 - x )
=> 15 / 2 = 25 - x
=> 7.5 = 25 - x
=> x = 25 - 7.5
x = 17.5
So, Average cost of liquid A =17.5 per liter


28. A modem __________

Answer is1980


Refer the above piechart 

30. If the difference between the two expenditures are represented by 18 in the pie-chart, then these expenditures possibly are ?



Explanation:

Solution is
Given

Central angle of 18 = ( 18 x 100 ) / 360 % of the total expenditure = 5% of the total expenditure.
From the given chart it is clear that
Out of the given combinations, only in combination (d) the difference is 5%
i.e. Paper Cost - Printing Cost = (25% - 20%) of the total expenditure = 5% of the total expenditure.
So the answer is option D
