= \(\frac { 25 }{ 100 }\) × 180
= 45

Question 6.
Convert 2 : 5 ratios into percentage.
Solution

= 40%

VI. Short Answer Type Questions

Question 1.
Simple interest for 5 years on some money is \(\frac { 2 }{ 5 }\) of total amount (A). Find the rate of simple interest
Solution
Amount = Principal + Simple Interest
Principal x Time x Rate 100


⇒ 5 PR = 40 P + 2 PR
⇒ 5R = 40 + 2R
⇒ 5R – 2R = 40
⇒ 3R = 40
⇒ R= \(\frac { 40 }{ 3 }\) = \(13\frac { 1 }{ 3 }\)
Hence, the required rate(RBSESolutions.com)of simple interest is \(13\frac { 1 }{ 3 }\) %

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

= 34,155

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,

Hence, the required rate of interest is 200% p.a.

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

Total Amount = Principal Amount + Interest
= 20,000 + 7,000
= Rs 27,000
Hence the total amount to be paid is Rs 27,000.

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:

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.

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

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

Hence, the required crystals are 5.4 x 10⁶.

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

Question 8.
A businessman sold two television sets at the rate of Rs 36,000 for each television set If he gets 20% profit on one television set and 20% loss on the other television set then find the percentage of profit or loss in total transaction?
Solution
Selling price of one television = Rs 36,000
Let cost(RBSESolutions.com)price be Rs x
Percentage profit = 20%

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

∴ Compound Interest = Total Amount – Principal Amount
= 97,240.50 – 84,000
= Rs 13,240.50

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

= 25,000
Hence the required cost price of scooter is Rs 25,000..

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%

∴Amount = Rs 26,956.80
Compound Interest = Amount – Principal
= 26,956.80 – 24,000
= Rs 2,956.80

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

⇒ x = 15,000
Hence the required population of town before 2 years = 15,000

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

∴ Payal has to return Rs 29,631 to the bank.

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.
