QUESTION: 3

Ms. Alina borrowed Rs. 650 at 6% per annum simple interest. What amount will she pay to clear her debt after 4 years?

Solution:

We know the formula for simple interest -

SI = (P × T × R)/100

Where,

SI = Simple interest

P = Principal

R = Rate of interest

T = Time period

SI = (650 × 4 × 6)/100 = Rs. 156

Amount = P + SI = 650 + 156 = Rs .806

∴ Amount she pays to clear her debt after 4 years = Rs. 806

QUESTION: 5

A telephone bill costs Rs. 13 for 19 minutes. What is the cost in rupees for 15 minutes 50 seconds? (Rounded to one decimal).

Solution:

We know that,

1 minute = 60 seconds

⇒ 19 minutes = 19 × 60 = 1140 seconds

Cost of telephone bill for 19 minutes = Rs. 13

⇒ Cost of telephone bill for 1 second = Rs. (13/1140)

Cost of telephone bill for 15 minutes 50 seconds = 950 × (13/1140) (∵ 15 min 50 sec = 950 sec)

⇒ Cost of telephone bill for 15 minutes 50 seconds = 65/6 = Rs. 10.8

∴ Cost of telephone bill for 15 minutes 50 seconds = Rs. 10.8

QUESTION: 7

Manoj is 2 times efficient than Anurag, together they can complete the work in 22 days. Anurag alone can complete the work in how many days?

Solution:

Let Anurag alone can do a piece of work in ‘x’ days.

⇒ Work done by Anurag in one day = 1/x

⇒ Work done by Manoj in one day = 2/x

Work done by Manoj and Anurag together in one day = 2/x + 1/x = 3/x

⇒ Time taken by Manoj and Anurag together to complete the work = 1/(3/x) = x/3

⇒ 22 = x/3

⇒ x = 66 days

∴ Time taken by Anurag alone to complete the work = 66 days

QUESTION: 14

Which of the following is a tsunami warning sign?

Solution:

As the coastal ocean waters recede from the shore, it often leaves large portions of the sea floor exposed. Individuals who do not recognize this as a common precursor to tsunami waves often find themselves gravitating toward the exposed shore. Unfortunately, they often perished as they rush to gather fish left high and dry on the exposed beach or to view never before seen rock and reef formations — only to be hit moments later by the incoming wall of water.

Experts believe that a receding ocean may give individuals more familiar with “nature’s tsunami warning signal” as much as a five minute warning to evacuate the area. This cycle may be repeated several times as successive wave crests arrive five minutes to an hour apart.

QUESTION: 28

Mr. Akshar sold a bus for Rs. 20,400 with a loss of 15%. At what price should the bus be sold to get a profit of 15%?

Solution:

Let the cost price of the bus be Rs. x.

Selling price (S.P.) of the bus = x – (15% of x) = 0.85x (∵ S.P. = C.P. – Loss)

⇒ 20400 = 0.85x

⇒ x = 20400/0.85 = Rs. 24,000

If profit = 15%:

S.P. of the bus = 24000 + (15% of 24000) (∵ S.P. = C.P. + Profit)

⇒ S.P. of the bus = 24000 + ((15/100) × 24000) = 24000 + 3600 = Rs. 27,600

∴ S.P. of the bus to get a profit of 15% = Rs. 27,600

QUESTION: 33

The cash difference between the selling price of an article at a profit of 2% and 12% is Rs. 3. The ratio of two selling prices is:

Solution:

Let the cost price (C.P.) of the article be Rs. x.

If profit is 2%:

Selling price (S.P.) of the article = x + (2% of x) = 1.02x (∵ S.P = C.P + Profit)

If profit is 12%:

Selling price (S.P.) of the article = x + (12% of x) = 1.12x

Cash difference between the above S.P’s = Rs.3

⇒ 1.12x – 1.02x = 3

⇒ 0.1x = 3

⇒ x = 30

The ratio of two selling prices = 1.02x : 1.12x = 51 : 56

∴ The ratio of two selling prices = 51 : 56

QUESTION: 40

Chandan travelled equal distance with speed of 3 km/hr, 4 km/hr and 8 km/hr and takes a total time of 42.5 minutes. Find the total distance in km.

Solution:

Let the total distance be ‘x’ km.

Chandan travelled equal distance.

⇒ He travelled (x/3) km each time.

We know that,

Time = Distance/Speed

⇒ Total time taken = [(x/3)/3] + [(x/3)/4] + [(x/3)/8]

⇒ 42.5 min = (x/9) + (x/12) + (x/24)

⇒ 42.5/60 = 17x/72 (∵ 1 hr = 60 min)

⇒ x = (17/24) × (72/17) = 3 km

∴ The total distance = 3 km

QUESTION: 42

A shopkeeper cheats to the extent of 8% while buying and selling fruits, by using tampered weights, his total gain in percentage is :

Solution:

∵ The seller cheats 8% while buying,

∴ Let he buys 108 gm in Rs. 100.

⇒ CP of 100 gm = 100 × 100/108 = 10000/108

Again, he cheats his customers while selling,

∴ He sells 92 gm in Rs. 100

⇒ SP of 100 gm = 100 × 100/92 = 10000/92

∴ Profit percentage = [10000/108 – 10000/92] / [10000/108] × 100 = 17.39%

QUESTION: 44

The term polyarchy was used by Robert Dahl to describe a form of government in which?

Solution:

In Western European political science, the term polyarchy was used by Robert Dahl to describe a form of government in which power is invested in multiple people. It takes the form of neither a dictatorship nor a democracy.

This form of government was first implemented in the United States and France and was gradually adopted by many other countries (Dahl, p. 234, 1989) Including Canada after the signing of the NAFTA agreement by Canadian Prime Minister Brian Mulroney in 1994.

According to Dahl, the fundamental democratic principle is “the continuing responsiveness of the government to the preferences of its citizens, considered as political equals” with unimpaired opportunities (Dahl, 1971).

A polyarchy is a state that has certain procedures that are necessary conditions for following the democratic principle. In semblance, the word polycracy describes the same form of government, although from a slightly different premise: a polycracy is a state ruled by more than one person, as opposed to a monocracy.

The word is derived from Greek poly which means "many" and kratos which means "rule" or "strength."

**Directions:** Read the data given and answer the following questions:

In a class of 60 students:

42 like Maths,

32 like English,

12 like neither Maths nor English.

Q. Students who like only Maths forms what percentage of the total number of students in the class?

Solution:

Given :

Total Students = 60

Students who like neither Maths nor English = 12.( Remaining students 60 - 12 = 48).

Students who like Maths = 42.

Students who like English = 32.

Number of Students who likes both English and Maths = 74 (42 + 32) - 48 = 26.

Number of Students who like Only English = 32 - 26 = 6.

Number of Students who like Only Maths = 42 - 26 = 16.

From the given data we get the following Venn diagram,

Students who like only Maths are 16 and total number of students in a class are 60.

(16/60)100 = 26.67%

Thus students who like only Maths forms 26.67 percentage of the total number of students in the class.

Which country among the following voted in 2015 to be the first country to allow three parent in-vitro fertilization?

Solution:

An independent panel of British scientists and experts has formally given nod to introduce so-called three-parent baby fertility treatments or mitochondrial gene therapy (MGT) procedures.

The panel tasked with reviewing the safety of MGT held that this practice should be cautiously adopted to prevent certain genetic diseases from being passed on to future generations.

Thus, it paves the way for the country to officially introduce the procedures. Earlier in February 2016, British Parliament voted to legalise three-parent baby fertility treatments or MGT procedures.

It was first country in the world to legalise creation of In-Vitro Fertilisation babies with DNA from three people. The world’s first three-parent baby boy was born in Mexico in April 2016 to a Jordanian couple with help of this new fertility technique which incorporates DNA from three people in embryo.

QUESTION: 97

Keerthana takes 9 hrs 20 minutes in walking a distance and riding back to same place where she started. She could walk both ways in 11 hrs 15 minutes. The time taken by her to ride back both ways is:

Solution:

Time taken by Keerthana to walk both ways = 11 hrs 15 minutes = (11 × 60) + 15 = 675 min

(∵ 1 hr = 60 min)

⇒ Time taken by Keerthana to walk one way = 675/2 = 337.5 min

Time taken by Keerthana in walking a distance and riding back = 9 hrs 20 min = (9 × 60) + 20 = 560 min

⇒ Time taken by Keerthana to ride one way = 560 – 337.5 = 222.5 min

⇒ Time taken by her to ride back both ways = 222.5 × 2 = 445 min = (7 × 60) + 25 = 7 hrs 25 min

∴ Time taken by her to ride back both ways = 7 hrs 25 min
