**1. About how many kilograms do you weigh?**

**Solution:-**

I weigh about 30 kilograms.

**2. So, 12 children like you put together will weigh about ………… kg.**

**Solution:-**

The weight of one child is 30 kg.

Then,

Weight of 12 children me put together = 12 × 30

= 360 kg

So, 12 children like me put together will weigh about 360 kg.

**3. About how much more does the whale shark weigh than 12 children like you put together?**

**Solution:-**

Whale shark weight was about 16000 kg.

Weight of 12 children me put together = 360 kg

Then, how much more does the whale shark weigh than 12 children,

= Whale shark weight – Weight of 12 children me put together

= 16000 – 360

= 15,640 kg

∴ the whale shark will weigh 15,640 kg more than the Weight of 12 children me put together.

**These log boats do not go very far. If the wind is helpful, they travel about 4 km in one hour.**

**1. How long will they take to go a distance of 10 km?**

**Solution:-**

These log boats take one hour to travel 4 km,

Then, log boat take two hours to travel = 2 × 4 = 8 km

But in half an hour the log boat will travel = 4/2 = 2km

∴the total time they take to go a distance of 10 km = 2 and half an hour.

For 2 hours boat travel = 8 km

For ½ an hour boat travel = 2 km

= 8 + 2 = 10 km

**2. Guess how far you can go in one hour if you walk fast.**

I can see sun is rising in the east and wind is blowing.

**2. Name two things that are lying to your west.**

**Solution:-**

Hut and tree are the two thing lying to my west.

**Look at the different types of boats.**

**Some boats have motors and go further into the sea. Since they go far out they can catch more fish. These boats travel faster, at** **the speed of about 20 km in one hour.**

**3. How far would the motor boats go in three and a half hours?**

**Solution:-**

As mentioned in the question these motor boats travel at the speed of about 20 km in one hour.

Then the distance travel by motor boats in three and half an hours = 20 × 3.5

= 70 km

**4. How much time will they take to go 85 km?**

**Solution:-**

As mentioned in the question these motor boats travel at the speed of about 20 km in one hour.

Then the distance travel by motor boats in four hours = 20 × 4

= 80 km

The distance travel by motor boats in ¼ hour = ¼ × 20

= 5 km

∴the total time taken by motor boat to go a distance of 85 km = 4 hours 15 minutes.

**Which Boat Gets How Much?**

In one trip the log boat brings about 20 kg of fish. But other types of boats bring a bigger catch as given in the table.

The table also shows the speed of each type of boat, which is how far each boat goes in one hour. Look at the table and calculate —

Type of boat | Catch of fish in one trip (in kg) | Speed of the boat (hoe far it goes in one hour) |

Log boat | 20 | 4 km per hour |

Long tail boat | 600 | 12 km per hour |

Motor boat | 800 | 20 km per hour |

Machine boat | 6000 | 22 km per hour |

**a) About how much fish in all will each type of boat bring in seven trips?**

**Solution:-**

Type of boat | Catch of fish in one trip (in kg) | Catch of fish in 7 trips (in kg) |

Log boat | 20 | 7 × 20 = 140 |

Long tail boat | 600 | 7 × 600 = 4200 |

Motor boat | 800 | 7 × 800 = 560 |

Machine boat | 6000 | 7 × 6000 = 42000 |

**b) About how far can a motor boat go in six hours?Solution:-**

Type of boat | Speed of the boat (hoe far it goes in one hour) | Distance covered by a boat in 6 hours (Distance = speed × time) |

Log boat | 4 km per hour | 4 × 6 = 24 km |

Long tail boat | 12 km per hour | 12 × 6 = 72 km |

Motor boat | 20 km per hour | 20 × 6 = 120 km |

Machine boat | 22 km per hour | 22 × 6 = 132 km |

**c) If a long tail boat has to travel 60 km how long will it take?**

**Solution:-**

From the given table long tail boat travel at a speed of 12 km per hour.

So, time taken by the long tail boat to travel 60 km = distance/speed

= 60 /12

= 5 hours.

**Women’s ‘Meenkar Bank’**

**The meeting of the Meenkar Bank has just begun. Fazila is the president. Twenty fisherwomen have made their own bank. Each saves Rs 25 every month and puts it in the bank.**

**1. How much money does the group collect each month?**

**Solution:-**

There are twenty fisherwomen in the Women’s ‘Meenkar Bank’.

Each saves ₹ 25 every month

So, total money collected in bank each month = 20 × 25

= ₹ 500

**2. How much money will be collected in ten years?**

**Solution:-**

So, from the above solution total money collected in bank per month = ₹ 500

Then, total money collected in bank in one year = 12 × 500

= ₹ 6000

Now, total money collected in bank in 10 years = 6000 × 10

= ₹ 60000

**Practice time**

**Why Don’t We Start a New Fish-drying Factory?**

**The women of Meenkar Bank also want to start a factory to dry fish. The Panchayat has given them some land for that. Over the years they have saved Rs 74,000. They find out how much they will need for the factory.**

**1. Fazila writes the things they need to buy to begin. See the table for the cost of each item and the number of items they want to buy. Find the total cost.**

Item | Price of each | Number of items | Cost (in ₹) |

Bore well for fresh water | ₹ 3000 | 1 | |

Bamboo rack for fish drying | ₹ 2000 | 20 | |

Cement tank | ₹ 1000 | 4 | |

Tray and knife | ₹ 300 | 20 | |

Bucket | ₹ 75 | 20 |

**Total cost to set up the factory = ____________**

**When fresh fish is dried it becomes its weight. In one month they plan to dry 6000 kg of fresh fish.**

**How much dried fish will they get in a month? ____________**

**Solution:-**

Item | Price of each | Number of items | Cost (in ₹) |

Bore well for fresh water | ₹ 3000 | 1 | 1 × 3000 = 3000 |

Bamboo rack for fish drying | ₹ 2000 | 20 | 20 × 2000 = 40000 |

Cement tank | ₹ 1000 | 4 | 4 × 1000 = 4000 |

Tray and knife | ₹ 300 | 20 | 20 × 300 = 6000 |

Bucket | ₹ 75 | 20 | 20 × 75 = 1500 |

Total cost to set up the factory,

= 3000 + 40000 + 4000 + 6000 + 1500

= ₹ 54500

In one month they plan to dry 6000 kg of fresh fish = 1/3 × 6000

= 2000 kg

**2. Floramma – let us first calculate for 6 kg of fresh fish.**

**We buy fresh fish for ₹ 15 per kg.**

**We sell dried fish foe ₹ 70 per kg.**

**(i) We dry 6 kg fresh fish to get _____ kg dried fish**

**Solution:-**

We dry 6 kg fresh fish to get 2 kg dried fish.

**(ii) For 6 kg fresh fish we have to pay 6 × __ = ₹ 90**

**Solution:-**

For 6 kg fresh fish we have to pay 6 × 15 = ₹ 90

**(iii) We will sell 2 kg dried fish and get 2 × __ = ₹ __**

**Solution:-**

We will sell 2 kg dried fish and get 2 × 70 = ₹ 140

**(iv) So if we dry 6 kg fresh fish we will earn __ – 90 = ₹ __**

**Solution:-**

So if we dry 6 kg fresh fish we will earn 140 – 90 = ₹ 50

**(v) But if we dry 6000 kg we can earn ₹ __ × 1000 in one month!**

**Solution:-**

But if we dry 6000 kg we can earn ₹ 50 × 1000 = ₹ 50000 in one month.

**3. Jhansi — I found that for 6000 kg fish we would need 1500 kg salt every month! Its price is Rs ₹ per kg.**

**Monthly costs:**

**a) Salt 1500 × 2 = ₹ ____**

**b) Packing and bus charges = Rs 3000**

**So the total monthly cost of drying and selling the fish = ₹ ____**

**Fazila — That sounds very good! Our calculations tell us that every month our Bank will earn Rs 44,000!**

**Solution:-**

(a) Salt 1500 × 2 = ₹ 3000

Then,

The total monthly cost of drying and selling the fish = ₹ 3000 + 3000

= ₹ 6000

Hence, earning = 50000 – 6000

= ₹ 44000
