Read the following paragraph to give your decision:
The smaller pesticide formulation units in India operate under heavy constraints such as obsolete technology, small scale of operation and dependence on large units for raw materials. In view of the loss of expensive material by the smaller units it is important to either eliminate or reduce losses to the extent possible through innovative and sustainable waste minimization techniques. Operating profit margins of the units are very low and small adverse conditions land these companies in trouble, Maximum losses suffered by these units are through poor housekeeping, sub-optional operating practices, and lack of proper opportunities for recycling waste.

Quantitative Aptitude [ Question No: 1 To 5 ] :
Find the simple interest (in ₹) on ₹6,800 at 8% per annum for 4 years.
Your Answer : (Not Answered)
Correct Answer : A
The simple interest is 2176.
Simple interest = P × R × T / 100.
\[ \frac{6800\times8\times4}{100}=2176 \]
2167, 2076 and 2716 are different arrangements of the digits and do not equal the product.
The yearly interest is 8% of 6,800 = 544, and for 4 years it is 4 × 544 = 2,176. The principal is not added, since simple interest is only the interest. The amount would be 8,976.
The third term of an H.P. is 1/7 and the fifth term is 1/11. What is the first term?
Your Answer : (Not Answered)
Correct Answer : A
The corresponding A.P. has a 3rd term of 7 and a 5th term of 11. So, \(a+2d=7\) and \(a+4d=11\). Subtracting the equations gives \(2d=4\), so \(d=2\). Substituting back, \(a+2(2)=7 \Rightarrow a+4=7 \Rightarrow a=3\). The first term of the A.P. is 3. The first term of the H.P. is the reciprocal, 1/3.
If the angle of elevation of cloud from a point 200 m above a lake is 30º and the angle of depression of its reflection in the lake is 60º, then find the height of the cloud above the lake.
Your Answer : (Not Answered)
Correct Answer : A
Let the cloud be \( H \) m above the lake surface, and let \( d \) be the horizontal distance from the observation point. The observer is 200 m above the lake, and the reflection sits \( H \) m below the surface.
Relative to the observer, the cloud is \( H - 200 \) up and the reflection is \( H + 200 \) down:
\[ \tan 30^{\circ} = \frac{H - 200}{d}, \qquad \tan 60^{\circ} = \frac{H + 200}{d} \]
Dividing eliminates \( d \):
\[ \frac{\tan 60^{\circ}}{\tan 30^{\circ}} = \frac{\sqrt{3}}{1/\sqrt{3}} = 3 = \frac{H+200}{H-200} \]
\[ H + 200 = 3H - 600 \quad\Longrightarrow\quad 2H = 800 \quad\Longrightarrow\quad H = 400 \text{ m} \]
The reflection is the mirror image in the water surface, so its depth below the surface equals the cloud's height above it - that is why the second numerator is \( H + 200 \) and not \( H - 200 \).
The length of a rectangular plot is 60% more than its breadth. If the diffrent between the length and the breadth of that rectangle is 24 cm, what is the area of the rectangle?
Your Answer : (Not Answered)
Correct Answer : C
Write the length in terms of the breadth and use the given difference.
\[ l = 1.6b \quad\Longrightarrow\quad l - b = 0.6b = 24 \]
\[ b = 40 \text{ cm}, \qquad l = 64 \text{ cm} \]
\[ A = 64 \times 40 = 2560 \text{ cm}^{2} \]
"60% more than the breadth" means \( 1.6b \), so the difference is 60% of the breadth, not of the length - taking 24 as 60% of the length would give \( l = 40 \) and a smaller rectangle.
Product of 4 and -3b is
Your Answer : (Not Answered)
Correct Answer : B
\[ 4 \times (-3b) = -12b \]
A positive times a negative is negative, and the numbers multiply as 4 and 3 to give 12.

Waste management process in India needs modernization.
Your Answer : (Not Answered)
Correct Answer : A
The key treats this inference as definitely true.
The paragraph calls for innovative and sustainable waste minimization techniques and complains of obsolete technology and poor opportunities for recycling, which together point to waste handling that needs modernizing. The key takes the statement as following directly.
The paragraph speaks of small pesticide units and not of India's waste management as a whole, so a stricter reading would call the inference only probably true. The key does not.
Direction for [ Question No: 7 To 7 ] :
Choose the correct alternative from the following.
Assertion (A) : Pluto is the coldest planet.
Reason (R) : It receives slanting rays of the sun.
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: A is true but R is false.
Pluto is indeed the coldest of the bodies traditionally counted as planets, at around \( -230^{\circ}\mathrm{C} \), so A is true. But the cause is its enormous distance from the sun - sunlight there is some 1600 times fainter than at the earth - not the slant of the rays, which is what makes the earth’s poles cold. R is false.
A school always has
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: Students
The question asks what is always present, not what usually is. A school exists to teach, and teaching requires someone taught, so students are essential - a building with no students is not a school but an empty building. A playground is a common facility but not a defining one, and many urban schools have none. A laboratory belongs to schools teaching science at a certain level, and not to primary schools. A uniform is a policy some schools adopt and others do not, and it varies entirely by country and tradition.
A mountain always has
Your Answer : (Not Answered)
Correct Answer : C
Correct answer: Peak
The question asks what is always present, not what usually is. A mountain rises to a summit, so it must have a peak. Snow lies only on high or cold mountains, a valley is beside it rather than part of it, and a ranger is a person.
General Awareness / General Knowledge (GK) [ Question No: 10 To 18 ] :
Which Tripura king first minted coins with the title 'Manikya'?
Your Answer : (Not Answered)
Correct Answer : A
The king is Ratna Manikya I.
Ratna Manikya I, who ruled in the fifteenth century, issued the earliest known coins of Tripura bearing the royal title Manikya. From his time the Manikya kings struck coins regularly, which makes the kingdom's coinage one of the main sources for dating its rulers.
The other kings came later and so cannot have been first: Dhanya Manikya ruled around 1500, Govinda Manikya in the seventeenth century and Krishna Kishore Manikya in the nineteenth.
Overwhelmed by the beauty of which fort did the British historian James Tod say that if he was offered a jagir in Rajasthan, he would choose _______ fort.
Your Answer : (Not Answered)
Correct Answer : A
James Tod would have chosen Bhainsrodgarh.
Bhainsrorgarh fort stands on a ridge at the meeting of the Chambal and Bamani rivers, near Rawatbhata in Chittorgarh district. Col. James Tod was so taken with the site that he wrote that if he were offered a jagir in Rajasthan, he would choose Bhainsrorgarh.
Chittorgarh, Mehrangarh and Junagarh are better known forts, but Tod's remark about choosing a jagir was made about Bhainsrorgarh.
Which of the following acids is found in ant's sting ?
Your Answer : (Not Answered)
Correct Answer : B
An ant's sting contains formic acid.
When an ant stings, it injects formic acid (methanoic acid), which causes pain and irritation. Its name comes from the Latin formica, ant. Rubbing a mild base such as baking soda on the sting neutralises the acid and gives relief.
Ascorbic acid is vitamin C, found in citrus fruits. Oxalic acid occurs in tomatoes and spinach. Acetic acid is the acid of vinegar.
Your Answer : (Not Answered)
Correct Answer : A
The brighter bulb has the smaller resistance.
Household bulbs are in parallel, so both have the same voltage across them: \[P = \frac{V^2}{R}\] With \(V\) fixed, power varies inversely with resistance, so the lower-resistance bulb dissipates more and glows brighter. In a series circuit the opposite would hold.
Your Answer : (Not Answered)
Correct Answer : A
DNS stands for Domain Name System.
It translates names people can remember into the numeric IP addresses machines use. It is a distributed hierarchy of servers, so no single machine holds the whole directory.
Your Answer : (Not Answered)
Correct Answer : B
An .INI file is a system configuration file.
It holds settings as plain text in sections with key-value pairs. Windows used INI files extensively before the registry replaced them, and many programs still use the format.
The world heritage site of “Terracotta Army” belongs to which of the following countries?
Your Answer : (Not Answered)
Correct Answer : D
It is in China.
The Terracotta Army was found near Xi'an in 1974 by farmers digging a well: some 8,000 life-size figures buried with Qin Shi Huang about 210 BC, each face individually modelled.
