On one such visit, the family happens to go to the island

restaurant named ‘ocean’ ,where the waiter informs that his

cousin ,Armando has a boat which could take their son ,Sam

swimming with the dolphins .Sam gets excited to hear this and the

next day ,he goes to the sea ,waving his family goodbye.

Armando gives him a life jacket and off they go into the sea

.Armando had a special way to call the dolphins ,by whistling . A

strange sound came out as he did so .Sam tried to whistle but

unfortunately nothing happened. ’Look’,cried Armando,pointing.

’Here they come ‘.

Sam couldn’t believe his eyes . A small school of dolphin was

dove into the water and the other dolphins swam alongside

.This was the most amazing game Sam had ever played.

This went on for a long time till Armando called him .

Sam climbed aboard and the boat was turned around .

Sam had one of the most adventurous experience of his

life and requested Armando to teach him the magical

whistle which brought the dolphins to him . Armando

finally agreed and after many failed attempts ,Sam could

come out with the perfect whistle.

The wind was now becoming stronger and a large wave

crashed over the side of the boat and threw Armando

lifeless on the floor . This made Sam nervous because all

he could see around was a large sea .Sam didn’t know

what to do .All of a sudden ,he whistled and he whistled

again and again ……… what he saw next was amazing .

About 30-40 dolphins came swimming through the waves

towards him .They pushed the boat with their heads .This

went on till the storm had passed .

Suddenly Armando cried in pain and got up .Sam told

Armando all that had happened .’Incredible ‘, cried

Armando and thanked the dolphins for all that they had

done .What a wonderful day they had !

Sam just couldn’t stop looking at the dolphins .They

vanished into the waves ,their fins shining in the rays of

the setting sun.

Now answer the following questions :

1) What did Sam do while the dolphins were pushing the

boats ?

Ans- While the dolphins were pushing the boat ,Sam

felt relieved and he went up on the deck trying to

make Armando as comfortable as possible .

2)’Thank you ,my friends .I fix the engine well now.

You can rest .

Who says this and to whom ?

Why does the speaker ask them to rest ?

Ans-The above line was spoken by Armando to the

dolphins .

The Dolphins had been pushing the boat for a long time

till the storm had passed and the sky was blue . This

probably made them very tired . So Armando asks them

to rest .

Make sentences with the following :

a) amazing

b) fantastic view

Lesson-

(i) The price at which we buy goods is called the Cost Price (CP). (ii) The price at which goods are sold is called the Selling Price(SP). (iii) When the SP is greater than CP, there is Profit or Gain.

SP > CP → Profit = SP – CP (iv) When the SP is less than CP, there is Loss.

SP < CP → Loss = CP – SP

Calculation of selling price and cost price

(v) SP = CP + Profit

(vi) SP = CP - Loss

(vii) CP = SP - Profit

(viii) CP = SP + Loss

1. A shopkeeper buys a football for ₹ 150 and sells it at ₹ 210.

What is his profit or loss? Solution:

Cost Price of football = ₹ 150

Selling Price of football = ₹ 210

210 > 150

As, S.P. > C.P.

So, he makes a profit

Profit = S.P. - C.P.

= ₹ (210 - 150)

= ₹ 60.

2. A merchant bought a table fan for ₹ 575 and sold for ₹ 500.

Find the loss of the merchant in the transaction?

Solution:

Cost Price of the table fan = ₹ 575

Selling Price of the table fan = ₹ 500

Loss = Cost Price - Selling Price

= ₹ (575 - 500)

= ₹ 75

Therefore, loss of the merchant is ₹ 75.

3.Maria sold a bicycle for ₹ 24900 at a profit of ₹ 600. Find the

price at which she bought it.

Solution:

Selling Price = ₹ 24900

Profit = ₹ 600

Cost Price = Selling Price – Profit

Cost Price = ₹ (24900 – 600)

= ₹24300

Therefore, Maria bought it at ₹ 24300.

Answer: ₹ 24300

4.Ron has a cycle worth ₹ 1800 and he wants to sell it at a

profit of ₹ 220. What should the selling price be?

Solution: Cost Price = ₹ 1800 Profit = ₹ 220

Selling Price = Cost Price + Profit Selling Price = ₹1800 + ₹220

= ₹ 2020 Selling price of the cycle = ₹ 2020 5. Diane sold a book worth ₹ 850 at a loss of ₹ 180. Find the selling price of the book. Solution: Cost Price = ₹ 850 Loss = ₹ 180 Since, Selling Price = Cost Price - Loss Selling Price = ₹850 - ₹180

= ₹ 670 Therefore, selling price of the book = ₹ 670 Answers: ₹ 670

6. A wrist watch was sold for ₹ 2050 at a loss of ₹ 30. What was the Cost price? Solution: Selling Price of the watch = ₹ 2050 Loss = ₹ 30 Now, C.P = S.P + Loss Cost Price of the watch = ₹2050 + ₹ 30 = ₹ 2080
