(e) Make two questions yourself from the price list. 1. 2.

#### Answer:

(a) Cost of 1 kg tomatoes = Rs 8 ∴ Cost of

12kg tomatoes = Rs 8 ÷ 2 = Rs 4

(b) Cost of 1 kg onions = Rs 10 Cost of 1 kg carrots = Rs 16 ∴ Cost of

12kg onions = Rs 10 ÷ 2 = Rs 5 And, Cost of

14kg carrots = Rs 16 ÷ 4 = Rs 4 The cost of

12kg onions is more than the cost of

14kg carrots.

(c) Cost of 1 kg potatoes = Rs 12 Cost of

14kg carrots = Rs 12 ÷ 4 = Rs 3 ∴ Cost of

12metre,

14metre and

34metre. • Using your string, draw a line of length

12metre on the floor. How many centimetres long is the line? ___________ Remember, 1 metre = 100 cm So

12metre = ……. cm

14metre = ……. cm

34metre = ……. cm Can you see that when we add

12and

14we get

34?

#### Answer:

1 m = 100 cm Line of

12m on the floor = 100 cm ÷ 2 = 50 cm So, a line of

12m on the floor is 50 cm long.

12m = 100 cm ÷ 2 = 50 cm

14m = 100 cm ÷ 4 = 25 cm

34m = 25 cm × 3 = 75 cm

#### Question 1:

**Sharing Milk** This bottle is full of milk and it holds one litre. The milk is put into 4 other bottles so that each bottle has

14litre of milk. • Shade the bottles to show the level of milk in each.

Remember, 1 litre = 1000 millilitres • How many millilitres of milk does each bottle have? _________

#### Answer:

- 1 litre = 1000 millilitres

Each bottle contains

14litre of milk. Thus, Quantity of milk in each bottle = 1000 mL ÷ 4 = 250 mL Thus, each bottle contains 250 mL milk.

#### Question 2:

**Sharing Milk** Shan poured 1 litre of milk into two bottles so that the first bottle holds

34litre and the other holds

14litre.

• Shade the level of milk in each bottle. • How many millilitres of milk does each bottle hold?

#### Answer:

- 1 litre = 1000 millilitres

One of the bottle holds

14L milk. Thus, Quantity of milk = 1000 mL ÷ 4 = 250 mL Another bottle holds

34L milk. Thus, Quantity of milk = 250 mL × 3 = 750 mL

#### Question 1:

**Balance the Weight**

• Choose from the weights above to make the two pans equal. In how many ways can you do it? (a) Draw the weights in the empty pan. Remember, 1kg = 1000 g

#### Answer:

We know 1 kg = 1000 g Thus, 2 kg = 2

×1000 g = 2000 g Following are the different ways in which we can make the two weights equal. 1) 1 kg + 500 g + 500 g = 2000 g 2) 1 kg + 500 g + 250 g + 250 g = 2000 g 3) 1 kg + 500 g + 250 g + 200 g + 50 g = 2000 g 4) 1 kg + 500 g + 200 g + 200 g + 100 g = 2000 g 5) 1 kg + 250 g + 250 g + 250 g + 200 g + 50 g = 2000 g We can make five different combinations to get 2 kg weight.

**Disclaimer:** The answer may vary from student to student. The answer provided here is for reference only.

#### Question 2:

**Balance the Weight** In how many different ways can you balance this weight of

34kg? (1) ………………… (2) ………………… (3) …………………

#### Answer:

We know 1 kg = 1000 g

Thus,

14kg =

1000÷4=250 g 34kg =

250 g×3=750 gFollowing are the different ways in which we can balance the weight of

34kg: 1) 500 g + 200 g + 50 g = 750 g

2) 250 g + 250 g + 250 g = 750 g

3) 250 g + 250 g + 200 g + 50 g = 750 g

#### Question 1:

**Practice Time** • There are 60 mangoes.

12of them are ripe. How many mangoes are ripe? • There are 32 children.

12of them are girls. How many children are boys? • There are 20 stars. A quarter of them are red. How many stars are red? How many are not red? • Ravi wants a pencil. It costs Rs 2. He gives a one-rupee coin, one half-rupee coin and one quarter-rupee coin. Is it enough?

#### Answer:

- Total mangoes = 60

12of them are ripe. Number of ripe mangoes = 60 ÷ 2 = 30 30 out of 60 mangoes are ripe.

- Total children = 32

12of them are girls. So,

12of them are boys. Number of boys = 32 ÷ 2 = 16 16 out of 32 children are boys.

- Total stars = 20

Quarter of them are red, which means

14of them are red. Number of stars that are red = 20 ÷ 4 = 5 5 out of 20 stars are red. Number of stars that are not red = 20 − 5 = 15

- Cost of a pencil = Rs 2

Money given by Ravi = Rs (1 + 0.50 + 0.25) = Rs 1.75 But, the pencil is for Rs 2. Money required = Rs (2.00 − 1.75) = Rs 0.25 Ravi did not give enough money to buy the pencil. Rs 0.25 more is required to buy the pencil.
