Show Answer

Answer: ((c))

3 @ 9 % 6 & 2 = 30

Symbol code	@	$	%	&
Meaning	+	−	×	÷

⇒ converting the equations:

1) 7 × 9 ÷ 3 − 5 = 4

= 16 ≠ 4

2) 4 × 3 + 6− 9 = 12

= 9 ≠ 12

3) 3 + 9 × 6 ÷ 2 = 30

= 30 = 30

4) 6 × 9 + 2−7 = 16

= 49 ≠ 16.

Thus, the equation 3 @ 9 % 6 & 2 = 30 is true.

Logic here is,

⇒ 4²θ 2 α 16 = 146

⇒ (16 × 10) + 2 – 16 = 146

⇒ 162 – 16 = 146

⇒ 146 = 146

⇒ 3² θ 5 α 18 = 77

⇒ (9 × 10) + 5 – 18 = 77

⇒ 95 – 18 = 77

⇒ 77 = 77

⇒ 4² θ 4 α 39 = ?

⇒ (16 × 10) + 4 – 39 = ?

⇒ 164 – 39 = ?

⇒ 125 = 125

Hence, 125 is the correct answer.

Which of the following elements has the highest electrical conductivity?

((a))
Copper
((b))
Silver
((c))
Zinc
((d))
Lead

Show Answer

Answer: ((b))

Silver

CONCEPT:

Conductivity: The measure of the ease at which an electric charge can pass through a material is called electrical conductivity.
Conductor: The material which has high conductivity is called the conductor.
Non-conductor: The material which has very low conductivity is called non-conductor.
Metal has high conductivity and non-metal has very low conductivity

EXPLANATION:

Electrical Conductivity is the evaluation of a material's ability to allow the transport of an electric charge.
Silver is by far the most electrically conductive metal on earth. Since silver has only one valence electron which is free to move around with little resistance, it has great electrical and thermal conductivity. So option 2 is correct.
After silver, copper is the second most electrically conductive metal. Gold and Aluminium are other metals which are good conductors of electricity.

Show Answer

Answer: ((b))

570

Let, principal = Rs. x

Rate = r%

According to problem,

⇒ 840 - x = (x × r × 3)/100

⇒ 840 - x = 3xr/100

⇒ xr/100 = 280 - x/3 ……. (1)

According to problem,

⇒ 1200 - x = (x × r × 7)/100

⇒ 1200 - x = 7xr/100

⇒ xr/100 = 1200/7 - x/7 …….. (2)

From (1) and (2) we get,

⇒ 1200/7 - x/7 = 280 - x/3

⇒ x/3 - x/7 = 280 - 1200/7

⇒ (7x - 3x)/21 = (1960 - 1200)/7

⇒ 4x/21 = 760/7

⇒ 4x = 760 × 3

⇒ x = 570

ALTERNATE SOLUTION:

Let the principal be P

SI after 3 years = 840 - P

SI after 7 years = 1200 - P

According to question, P is constant

(840 - P) × 100/(R × 3) = (1200 - P) × 100/(R × 7)

7 × (840 - P) = 3 × (1200 - P)

5880 - 7P = 3600 - 3P

Show Answer

Answer: ((b))

5/2√3

⇒ cosec²𝜃 = 25/16

⇒ cosec𝜃 = 5/4 [∵ 𝜃 is acute]

⇒ sin𝜃 = 4/5

⇒ cos𝜃 = √(1 - 16/25)

⇒ cos𝜃 = 3/5

∴ √(cot𝜃 + tan𝜃)

$\begin{array}{l} \Rightarrow \sqrt {\frac{{sin\theta }}{{cos\theta }} + \frac{{cos\theta }}{{sin\theta }}} \ \Rightarrow \sqrt {\frac{{si{n^2}\theta + co{s^2}\theta }}{{sin\theta cos\theta }}} \end{array}$

$\begin{array}{l} \Rightarrow \frac{1}{{\sqrt {\left[ {\left( {\frac{4}{5}} \right) \times \left( {\frac{3}{5}} \right);} \right]} }}\ \Rightarrow \frac{5}{{2\sqrt 3 }} \end{array}$

If a certain sum becomes 2 times in 5 years at compound interest, then in how many years, it will become 8 times?

((a))
10
((b))
20
((c))
15
((d))
30

Show Answer

Answer: ((c))

Let,

Principal = P

Rate = r%

In first case,

Amount = 2P.

Rate = r%

Time = 5 years.

∴ 2P = P[1 + (r/100)]⁵ [∵ A = P × [1 + (r/100)]ⁿ; A = amount, P = principal, r = rate, n = no. of year]

⇒ 2 = [1 + (r/100)]⁵ ......... (1)

In second case,

Let, sum become 8 times in the time n years,

Amount = 8P

Time = n years

∴ 8 = (1 + (r/100))ⁿ

⇒ 2³ = [1 + (r/100)]ⁿ ....... (2)

Using eqn. (1) and (2), we get;

⇒ ([1 + (r/100)]⁵)³ = (1 + (r/100))ⁿ

⇒ [1 + (r/100)]¹⁵ = (1 + (r/100))ⁿ

Thus, n = 15 years

Show Answer

Answer: ((b))

439 : 641

Let, capacity of each bottle = x

Ratio of milk and water in first bottle = 2 ∶ 3

∴ Quantity of milk in first bottle = 2x/5

∴ Quantity of water in first bottle = 3x/5

Ratio of milk and water in second bottle = 3 ∶ 5

∴ Quantity of milk in second bottle = 3x/8

∴ Quantity of water in second bottle = 5x/8

Ratio of milk and water in third bottle = 4 ∶ 5

∴ Quantity of milk in third bottle = 4x/9

∴ Quantity of water in third bottle = 5x/9

∴ Total quantity of milk,

⇒ 2x/5 + 3x/8 + 4x/9

⇒ (144x + 135x + 160x)/360

⇒ 439x/360

∴ Total quantity of water,

⇒ 3x/5 + 5x/8 + 5x/9

⇒ (216x + 225x + 200x)/360

⇒ 641x/360

∴ the ratio of milk and water respectively in the large bottle,

⇒ 439x/360 ∶ 641x/360

⇒ 439 ∶ 641

A and B together can complete a work in 20 days. They started together but after 4 days A left the work. The remaining work was completed by B alone in 24 more days. In how many days can A complete the entire work alone?

((a))
75
((b))
25
((c))
45
((d))
60

Show Answer

Answer: ((d))

(A + B) can complete a work in = 20 days

∴ (A+B)’s 1 day’s work = 1/20 …… (1)

∴ (A+B)’s 4 day’s work = 4/20 = 1/5

∴ Remaining work = 1 - 1/5 = 4/5

∴ B completes 4/5 work in = 24 days

∴ B can complete the work in = 24 × 5/4 = 30 days

∴ B’s 1 day’s work = 1/30 …… (2)

From (1) and (2) we get,

A’s 1 day’s work,

⇒ 1/20 - 1/30

⇒ (3 - 2)/60

⇒ 1/60

∴ A can complete the work in = 60 days

136

Ram is five times as efficient as Rohit. Ram can complete a work in 60 days less than Rohit. If both of them work together then in how many days the work would be completed?

((a))

((d))
20

Show Answer

Answer: ((b))

12.5

Let, efficiency of Rohit = x/day and efficiency of Ram = 5x/day

Let, Rohit can complete the work in = y days

∴ Ram can complete the work in = (y - 60) days

According to problem,

⇒ x × y = 5x × (y – 60)

⇒ y = 5y – 300

⇒ 4y = 300

⇒ y = 75

Let, when they work together they can complete the work in = z days

According to problem,

⇒ x × 75 = (x + 5x) × z

⇒ 75 = 6z

⇒ z = 12.5

∴ when they work together they can complete the work in = 12.5 days

Alternate Method

Given:

Ram is five times as efficient as Rohit

Let, efficiency of Rohit = x/day and efficiency of Ram = 5x/day

Ram can complete a work in 60 days less than Rohit.

It means, 5x - x = 60

4x = 60

x = 15 days

Therefore, Rohit takes 15 days and Ram takes 75 days

! day of work compleed in

$\frac{1}{15}+\frac{1}{75}=\frac{2}{25}$ days

So, total work completed in $\frac{25}{2}$ days

Show Answer

Answer: ((c))

Let, original length = x and breadth = y

∴ Original area = xy

After 20% increase, length = x + x × 20/100 = 1.2x

After 30% increase, breadth = y + y × 30/100 = 1.3y

∴ New area = 1.2x × 1.3y = 1.56xy

∴ Percentage increase,

⇒ (1.56xy – xy)/xy × 100%

⇒ 0.56 × 100%

⇒ 56%

It is the great formative _____ of our life, brief but powerful.

((a))

period

The word ‘lesson’ means ‘a teaching’ and youth is not a lesson. The word ‘resource’ means ‘a stock or supply of money, materials, staff, and other assets that can be drawn on by a person or organization in order to function effectively’ and makes no sense here.

161

Show Answer

Answer: ((a))

The word here should be such that it goes with the preposition ‘in’. Thus ‘rejoice’ which means ‘to celebrate’ fits here. The other words make no sense if used with ‘in.’ Thus option 1 is the correct answer.

164

feelings pure and with _____ unworldly.

((a))
ambitions
((b))
passively
((c))
religiously
((d))
resources

Show Answer

Answer: ((a))

ambitions

The word here must be a noun as can be understood from the sentence. Thus the adverbs ‘passively’ and ‘religiously’ are eliminated. Thus either 1 or 4 will fit here.The meanings of the words are:

Ambitions=> aims

Passively=> in an accepting manner, without active response or resistance

Religiously=> in a way that relates to or conforms with a religion.

Resources=> a stock or supply of money, materials, staff, and other assets that can be drawn on by a person or organization in order to function effectively.

Thus option 1 is the correct answer.

The sentence talks about feelings and humane objects thus ‘ambitions’ fits in the context. ‘Resources’ is incorrect here.

A passage is given with five questions following it. Read the passage carefully and select the best answer to each question out of the given four alternatives.

Antarctica is a mostly unpopulated continent. It is the coldest, driest and most remote place in the world. And it is the world's only continent that does not have a native population. No single country owns the Antarctic. However, a number of countries, including Argentina, Australia, Chile, NewZealand, France and the United Kingdom, have already laid claim to the Antarctic and others will probably follow. In some areas of the continent, two countries claim the same land. The Antarctic Treaty was signed in 1959 and creates the rules for the exploration of the Antarctic. The treaty forbids military activity in the Antarctic, as well as mining. Many countries, however, think that there are valuable materials and minerals locked up under the frozen Antarctic ice. In addition, the treaty bans nuclear testing as well as dumping nuclear waste. The Antarctic Treaty was made to protect the continent and avoid further disputes. By 2048, the treaty must be renewed. New rules and regulations could be imposed by then. Currently, almost all of the 70 bases in the Antarctic are used for research and scientific activity. The snow-covered continent is perfect for tracking satellites and space research because it offers clear blue, cloudless skies. Climatologists are studying the development of the ozone layer with growing concern. It was here that a hole in the layer was discovered for the first time. More than 4000scientists operate the research stations in the Antarctic summer, while only about a thousand populate the continent during the harsh and severe winters. Environmentalists fear that exploiting Antarctica for military and economic reasons will damage the environment. At present, there is no economic activity in Antarctica, except for cruise ships that travel around the continent. This could change if a new treaty allows mining in the Antarctic. As mineral resources are dwindling in other areas, nations could turn to Antarctica to find and exploit valuable raw materials. Some geologists say that there are over 200 billion barrels of oil under the Antarctic ice. At the moment getting at these reserves would be very expensive. In addition, economic experts claim that there are large amounts of coal, nickel and copper under the Antarctic ice.

165
