RRB NTPC Previous Year Paper Tier-I 2016 (Set 3) - 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?

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 3) - Question 3

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

RRB NTPC Previous Year Paper Tier-I 2016 (Set 3) - 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).

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 3) - Question 5

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

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 3) - Question 7

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

RRB NTPC Previous Year Paper Tier-I 2016 (Set 3) - Question 14

Which of the following is a tsunami warning sign?

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 3) - Question 14

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.

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%?

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 3) - Question 28

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

RRB NTPC Previous Year Paper Tier-I 2016 (Set 3) - 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: 

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 3) - Question 33

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

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.

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 3) - Question 40

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

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 3) - Question 42

∵ 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%

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

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 3) - Question 44

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."

The pie chart represents the favorite stars (Bollywood stars SRK, SK, AK, HR and VD) of the people of a family.

Q. If there are 40 people in the family, what is the difference between those who like AK and those who like VD?

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 3) - Question 89

From the pie chart, we can observe that 15% and 10% of the people of a family like AK and VD respectively.

The difference in the percentage between those who like AK and those who like VD = 15 – 10 = 5%

⇒ The difference between those who like AK and those who like VD = 5% of 40 = (5/100) × 40 = 2

∴ The difference between those who like AK and those who like VD = 2
