RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - Question 1

Ritesh sold a pen for Rs. 36 with a profit of 20%. If it were sold for Rs. 33, then what could be the percentage of profit or loss?

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - Question 1

As per the given data,

Let the cost price of the pen be Rs.x

⇒ Profit % = (SP - CP)/CP × 100

⇒ 20 = (36 - x)/x × 100

⇒ 20x = 3600 - 100x

⇒ 120x = 3600

⇒ x = 30

∴ Cost price of the pen is Rs.30

Also given that he sold the pen at Rs.33

By comparing with cost price of the pen Rs.30 with selling price of the pen Rs.33, we can say it as profit

⇒ Profit % = (33 - 30)/30 × 100 = 10 %

∴ Percentage of profit is 10%

RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - Question 3

If the angles of the triangle are in the ratio of 1 : 4 : 7, the find the ratio of the greatest angle to the smallest angle?

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - Question 3

Let the angles of a triangles are in the ratio of x : 4x : 7x

We know that sum of the angles in a triangle = 180°

⇒ x + 4x + 7x = 180°

⇒ 12x = 180

⇒ x = 15°

∴ Smallest angle = 15°

Greatest angle = 7x = 7(15) = 105°

Ratio of the greatest angle to the smallest angle = 105 : 15 = 7 : 1

4 years ago, the ratio of Vikas’s to Rahul’s age was 3 : 5. After 6 years, this ratio would become 4 : 5. Find present age of Rahul?

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - Question 9

Let the present age of vikas and Rahul be x and y

Given that 4 years ago, the ratio of Vikas’s to Rahul’s age was 3 : 5

⇒ (x - 4)/(y - 4) = 3/5

⇒ 5x - 20 = 3y - 12

⇒ 5x - 3y = 8          ----equation (1)

Also given that after 6 years, this ratio would become 4 : 5

⇒ (x + 6)/(y + 6) = 4/5

⇒ 5x + 30 = 4y + 24

⇒ 5x - 4y = - 6          ----equation (2)

By subtracting equation (2) from equation (1), we get

y = 14

∴ Present age of Rahul y = 14 years

RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - Question 13

Aparna changes the marked price of an item to 50% above its C.P. What % of discount allowed in approximately to gain 10%?

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - Question 13

12 men and 16 women together can complete a work in 4 days. It takes 80 days for man alone to complete the same work, then how many days would be required for one woman alone to complete the same work?

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - Question 31

Work done by men in one day = 1/80

Work done by 12 men in one day = 12/80

Work done by 12 men and 16 women in one day = 1/4

∴ Work done by 16 women in one day = 1/4 - 12/80 = 1/10

Work done by one women in one day = 1/10 × 1/16 = 1/160

Find the total Simple Interest on Rs. 500 at 7% per annum, on Rs. 700 at 10% per annum and on Rs. 1000 at 4% per annum for 3 years?

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - Question 34

We know that S.I = P × T × R/100 where S.I = Simple Interest

⇒ S.I1 = 500 × 1 × 7/100 = Rs.35

⇒ S.I= 700 × 1 × 10/100 = Rs.70

⇒ S.I3 = 1000 × 1 × 4/100 = Rs.40

Also given that when one observation is included the new mean is 16

∴ mean of 11 observations = 16

∴ Sum of 11 observations = 11 × 16 = 176

11th observation = sum of 11 observations - sum of 10 observations = 176 - 170 = 6

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - Question 55

Let the investment of Jalal, Amit and Feroz be x, y and z

Given that invests 4 times as much as Amit and Amit invests ¾ of what Feroz invests.

⇒ x = 4y and y = 3/4 z

Given that total profit at the end of year is Rs.19000

⇒ x + y + z = 19000

⇒ 4y + y + 4y/3 = 19,000

⇒ 12y + 3y + 4y = 57,000

⇒ 19y = 57,000

⇒ y = 3,000

Jalal investment (x) = 4y = 4 (3, 000) = Rs.12,000

A salesman visits 274 houses in a town to find out the views about three products X, Y and Z. He found that 157 use X, 98 use only X, 22 use all the three, 14 use X and Z but not Y, 39 use Y and Z, 48 use only Y.

Q. Which product is the most popular one?

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - Question 62

A salesman visits 274 houses in a town to find out the views about three products X, Y and Z.

People who use product X = 157,

People who use only product X = 98

People who use all three product X, Y and Z = 22

People who use X and Z product but not Y = 14

People who use Y and Z product = 39

People who use only product Y = 48

Therefore,

People who use only Y and Z = people who use Y & Z – people who use all = 39 – 22 = 17 

People who use only Z = all people – people who use X – people who use only Y – people who use only Y and Z = 274 – 157 – 48 – 17 = 52

People who use only X and Y

People who use only X and Y product = people who use X – people who use only X and Z – people who use only X – people who use all three = 157 – 14 – 98 – 22 = 23.

Hence, X is most popular product.

Q. How many use product Z only?

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - Question 63

A salesman visits 274 houses in a town to find out the views about three products X, Y and Z.

People who use product X = 157,

People who use only product X = 98

People who use all three product X, Y and Z = 22

People who use X and Z product but not Y = 14

People who use Y and Z product = 39

People who use only product Y = 48

Therefore,

People who use only Y and Z = people who use Y & Z – people who use all = 39 – 22 = 17 

People who use only Z = all people – people who use X – people who use only Y – people who use only Y and Z = 274 – 157 – 48 – 17 = 52

People who use only X and Y

People who use only X and Y product = people who use X – people who use only X and Z – people who use only X – people who use all three = 157 – 14 – 98 – 22 = 23.

Therefore, 52 people used product Z only.

Q. What fraction used at least two products?

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - Question 64

A salesman visits 274 houses in a town to find out the views about three products X, Y and Z.

People who use product X = 157,

People who use only product X = 98

People who use all three product X, Y and Z = 22

People who use X and Z product but not Y = 14

People who use Y and Z product = 39

People who use only product Y = 48

Therefore,

People who use only Y and Z = people who use Y & Z – people who use all = 39 – 22 = 17 

People who use only Z = all people – people who use X – people who use only Y – people who use only Y and Z = 274 – 157 – 48 – 17 = 52

People who use only X and Y

People who use only X and Y product = people who use X – people who use only X and Z – people who use only X – people who use all three = 157 – 14 – 98 – 22 = 23.

Therefore, people who used at least two products = people who used two products + people who used all products = people who used X & Y only + people who used X & Z only + people who used Y & Z only + people who used all = people who used X & Y only + people who used X & Z only + people who used Y & Z = 23 + 14 + 39 = 76.

Therefore, 76/274 fraction of total people used at least two products.

A superfast Duronto express running at 90 kmph overtakes a bike running at 36 kmph in 25 seconds. What is the length of the train in meters?

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - Question 84

When a train over takes another object such as bike, whose length is negligible compared to the length of the train

∴ Distance travelled by the train over taking the bike is same as the length of the train

Length of the train = Relative speed between the train and the bike × time taken

Relative speed of the train = (90 - 36) = 54 × 5/18 = 15 (∵ they are travelling in same direction)

∴ Length of the train = 15 × 25 = 375 m

Detailed Solution for RRB NTPC Previous Year Paper Tier-I 2016 (Set 2) - Question 85

Let the numbers be x, y and z

As per the given data,

y = 3x

x = y/3

⇒ y = 2z

⇒ z = y/2

Given that average of the three numbers is 66

⇒ (x + y + z)/3 = 66

⇒ (y/3 + y + y/2)/3 = 66

⇒ (2y + 6 y + 3y)/(3 × 6) = 66

⇒ 11y = 66 × 18

⇒ y = 108

∴ First number x = y/3 = 108/3 = 36
