Hence, the required rate(RBSESolutions.com)of simple interest is \(13\frac { 1 }{ 3 }\) %

RBSE Solutions

Question 2.
The population of a town before 3 years was 25,000. If grows at 10%, 15% and 8% in consecutive three years. Find the present population.
Solution
Present Population
RBSE Solutions for Class 8 Maths Chapter 13 Comparison of Quantities Additional Questions img-8
= 34,155

RBSE Solutions

Question 3.
Find the rate of which a sum of money will \(\frac { 81 }{ 16 }\) times itself in one year, if the interest is compounded quarterly.
Solution
Let R% yearly be the rate of interest.
Then quarterly(RBSESolutions.com)rate of interest = \(\frac { R }{ 4 }\) %
1 year = 4 quarters
According to question,
RBSE Solutions for Class 8 Maths Chapter 13 Comparison of Quantities Additional Questions img-9
Hence, the required rate of interest is 200% p.a.

RBSE Solutions

Question 4.
A farmer took loan of Rs 20,000 from Nationalized Bank for his agricultural work. If bank charges interest on the rate of 14% yearly and the interest is compounded yearly. What is the total amount to be paid after 2 years and 6 months?
Solution
Loan amount = Rs 20,000
Rate of(RBSESolutions.com)interest = 14% yearly
Time = 2 years 6 months
= 2 years + \(\frac { 6 }{ 12 }\) year
= \(\frac { 5 }{ 2 }\) years
RBSE Solutions for Class 8 Maths Chapter 13 Comparison of Quantities Additional Questions img-10
Total Amount = Principal Amount + Interest
= 20,000 + 7,000
= Rs 27,000
Hence the total amount to be paid is Rs 27,000.

RBSE Solutions

Question 5.
A farmer has enough food for 20 animals for 6 days. If he increases 10 more animals then for how many days this food will be enough?
Solution:
RBSE Solutions for Class 8 Maths Chapter 13 Comparison of Quantities Additional Questions img-11
Let required days be x.
Here inverse relation occurred.
30 : 20 :: 6 : x
Product of outer(RBSESolutions.com)terms = Product of middle terms
⇒ 30 × x = 20 × 6
⇒ \(x=\frac { 20\times 6 }{ 30 } =4\)
Hence, the required days are 4.

RBSE Solutions

Question 6.
Suppose in 2 Kg. sugar, there are 9 x 106 crystals. How many crystals will be there in 1.2 kg. sugar?
Solution
RBSE Solutions for Class 8 Maths Chapter 13 Comparison of Quantities Additional Questions img-12
Let x crystals be in 1.2 kg sugar.
Then, 2 : 1.2 :: 9 × 106 : x
Product of outer terms = Product of middle terms
⇒ 2 × x = 1.2 × 9 × 106
RBSE Solutions for Class 8 Maths Chapter 13 Comparison of Quantities Additional Questions img-13
Hence, the required crystals are 5.4 x 106.

RBSE Solutions

Question 7.
In class VIII 60% students in Maths obtained grade A out of 45 students. How many students got A grade in Maths?
Solution
Total number of students = 45 %
of students getting grade A in Maths = 60%
Number of(RBSESolutions.com)students getting grade A in Maths
= 60% of 45 = \(\frac { 60 }{ 100 }\) × 45 = 27
∴ Number of students getting grade A in Maths = 27

Selling price of one television = Rs 36,000
Let cost(RBSESolutions.com)price be Rs x
Percentage profit = 20%

RBSE Solutions

Question 9.
Naval borrowed Rs 84,000 from a nationalized bank for \(1\frac { 1 }{ 2 }\) years at the rate of 10% per annum. Compute the total compound interest(RBSESolutions.com)payable by Naval after \(1\frac { 1 }{ 2 }\) year, if the interest is compound half yearly.
Solution
\(1\frac { 1 }{ 2 }\) years = 3 half years
Principal Amount = Rs 84,000
Rate = 10%
= 5% half yearly
Total amount = principal amount
RBSE Solutions for Class 8 Maths Chapter 13 Comparison of Quantities Additional Questions img-16
∴ Compound Interest = Total Amount – Principal Amount
= 97,240.50 – 84,000
= Rs 13,240.50

RBSE Solutions

Question 10.
Rahul sold a scooter for Rs 18,750 at a loss of 25%. Find the cost price of the scooter.
Solution
Let the required(RBSESolutions.com)cost price of scooter be Rs x.
Loss = 25% of x
Selling Price = Rs 18,750
Therefore,
Cost Price – Loss = Selling Price
RBSE Solutions for Class 8 Maths Chapter 13 Comparison of Quantities Additional Questions img-17
= 25,000
Hence the required cost price of scooter is Rs 25,000..

RBSE Solutions

Question 11.
Find compound interest of Rs 24,000 for \(1\frac { 1 }{ 2 }\) years at the rate of 8% per year, when interest is calculated yearly.
Solution
Time = \(1\frac { 1 }{ 2 }\) year
Principal(RBSESolutions.com)Amount = Rs 24,000
Annual interest rate = 8%
RBSE Solutions for Class 8 Maths Chapter 13 Comparison of Quantities Additional Questions img-18
∴Amount = Rs 26,956.80
Compound Interest = Amount – Principal
= 26,956.80 – 24,000
= Rs 2,956.80

RBSE Solutions

Question 12.
The population of a town increases at annual rate of 8%. If present population of town is 17,496 then find population of town before 2 years. Solution
Present Population = 17,496
Time = 2 years
Rate of increase = 8%
Let the(RBSESolutions.com)population of town before 2 years be x.
Hence, Present Population
RBSE Solutions for Class 8 Maths Chapter 13 Comparison of Quantities Additional Questions img-19
⇒ x = 15,000
Hence the required population of town before 2 years = 15,000

RBSE Solutions

Question 13.
Payal took loan of Rs 20,000 for parlor from a nationalized(RBSESolutions.com)Bank. How much amount will she repay after 3 years, if annual rate of interest is 14% and interest is compounded annually?
Solution
Amount borrowed from Bank (P) = Rs 20,000
Time (n) = 3 years
Rate of interest = 14%
Condition = Interest is compounded annually
RBSE Solutions for Class 8 Maths Chapter 13 Comparison of Quantities Additional Questions img-20
∴ Payal has to return Rs 29,631 to the bank.

RBSE Solutions

Question 14.
A businessman purchased goods for Rs 14,000. He paid Rs 50 for freight(RBSESolutions.com)and Rs 150 for wages. To earn 5% profit, at what price he should sell goods?
Solution
Cost price of goods = Rs 14,000
Auto rent = Rs 50
Wages = Rs 150
Total cost(RBSESolutions.com)price of goods
= Rs (14,000 + 50 + 150)
= Rs 14,200
Wants to earn profit = 5%
∴Profit = 5% of 14,200
= \(\frac { 14,200X5 }{ 100 }\)
= Rs 710
∴ Selling price of goods = Rs(14,200 + 710)
= Rs 14,910.

Question 1.
Describe the historical water management system of Udaipur.
Answer:
Many types of water resources are found in every region of Rajasthan. In ancient time water was supplied to the people from these resources and well maintained. The then rulers did many efforts of water collection and conservation. Efforts were made by Ranas of Udaipur. Lake of Jaismand is a good example of it.

It was built by the Maharana of Mewar Jai Singh, from 1687-1691 A.D. on river Gomati. Which is considered as the world’s largest man-made lake freshwater. The examples of the oldest methods of the conservation of water by turning and joining rivers and lakes can be seen in Mewar Chickalwas canal. It was built by Maharana Fateh Singh by building a dam on river Ahad to supply excess water of rainy season in Fateh Sagar. It is 6 km away from Udaipur. In this way 118 years ago water of Ahad river was reached to Fateh Sagar.

The serialy built ponds in 470 km are spread in valley area and join rivers by the then rulers in people’s interest. It is an excellent and praiseworthy work in the field of water collection and conservation which is being continue smoothly even today.
The best example of water management resources in ancient times in the world can be seen in Udaipur Basin. To quote some of them as Govardhan Sagar, Dhood Talai, Pichhola lake, Amar Kund, Kumaria pond, Ranga Sagar Swaroop Sagar and Fateh Sagar. During the rainy seasons when all these water sources are filled to the brim, their water level gets merged.
