How many legs?	4	8	12
How many cats?	1	2

So 28 legs mean __________ cats.

Answer:

Number of legs of 1 cat = 1 × 4 = 4 Number of legs of 2 cats = 2 × 4 = 8 Number of legs of 3 cats = 3 × 4 = 12 Continuing in the same manner, we can easily fill the given table.

How many legs?	4	8	12	16	20	24	28	32
How many cats?	1	2	3	4	5	6	7	8

From the table, we can see that 7 cats have 28 legs.

Question 2:

Billo has kept his chickens in a box. He counted 28 legs. How many chickens are there?

Question 1:

A frog jumps 3 steps at a time starting from 0. • Count the jumps he takes to reach 27. So, he has taken 27 ÷ 3 = _______ jumps.

• He has taken _________ jumps, if he is at 36. • If he is at 42, he has taken _________ jumps. Starting from 0, a rabbit jumps 5 steps at a time. • In how many jumps does he reach 25? ____________ • He reaches ____________ after taking 8 jumps. • He needs ____________ jumps to reach 55.

Answer:

Number of jumps taken by the frog to cover 3 steps = 1

Number of jumps taken by the frog to cover 27 steps = 27 ÷ 3 = 9 So, he has taken 27 ÷ 3 = 9 jumps.

Number of jumps taken by the frog to cover 3 steps = 1

Number of jumps taken by the frog to cover 36 steps = 36 ÷ 3 = 12 He has taken 12 jumps, if he is at 36.

Number of jumps taken by the frog to cover 3 steps = 1

Number of jumps taken by the frog to cover 42 steps = 42 ÷ 3 = 14 If he is at 42, he has taken 14 jumps.

Number of jumps taken by the rabbit to cover 5 steps = 1

Number of jumps taken by the frog to cover 25 steps = 25 ÷ 5 = 5 Thus, the rabbit will reach 25 in 5 jumps.

Number of steps covered in 1 jump = 5

Number of steps covered in 8 jumps = 5 × 8 = 40 He reaches 40 after taking 8 jumps.

Number of jumps taken by the rabbit to cover 5 steps = 1

Number of jumps taken by the frog to cover 55 steps = 55 ÷ 5 = 11 He needs 11 jumps to reach 55.

Question 1:

He took 28 shells for one necklace. 112 − 28 = 84 Now he was left with 84 shells. Again he took 28 more shells for the second necklace. • How many shells are left now? __________ Then he took shells for the third necklace. • So he was left with ___________ shells. • How many necklaces can Dhruv make from 112 shells? _________ • Are the shells enough for making necklaces for all his friends? ___________

Answer:

After making the first necklace, Dhruv was left with 84 shells.

Number of shells used for the second necklace = 28 Number of shells left with Dhruv = 84 − 28 = 56

Working: 84-2856Thus, Dhruv was left with 56 shells after making the second necklace.

Dhruv took 28 more shells for making the third necklace.

Number of shells left with Dhruv after making third necklace = 56 − 28 = 28

Dhruv made a necklace of 28 shells for each of his three friends.

After making the necklaces for his friends, he was left with 28 shells. So, he could make one more necklace with the remaining shells. Thus, Dhruv could make a total of 4 necklaces with 112 shells.

Yes, the number of shells were enough for making necklaces for all the friends. After making 3 necklaces for his friends, 28 shells were still left with Dhruv.

Question 2:

Kannu made a necklace of 17 sea-shells. How many such necklaces can be made using 100 sea-shells?

Answer:

Kannu used 17 sea shells to make a necklace. Number of sea shells used in 1 necklace = 1 ×17 = 17 Number of sea shells used in 2 necklaces = 2 × 17 = 34 Similarly, the number of sea shells used in 6 necklaces = 6 × 17 = 102 So, 102 sea shells are required to make 6 necklaces. Total number of sea shells available for making necklaces = 100 Thus, Kannu can make 5 necklaces by using 100 sea shells.

Question 1:

One carton can hold 85 soap bars. Shally wants to pack 338 soap bars. How many cartons does she need for packing all of them?

Answer:

Number of soap bars that can be packed in 1 carton = 85 Number of soap bars that can be packed in 2 cartons = 2 × 85 = 170 Number of soap bars that can be packed in 3 cartons = 3 × 85 = 255 Number of soap bars that can be packed in 4 cartons = 4 × 85 = 340 If we take 3 cartons, then we can pack only 255 soap bars. Thus, Shally will need 4 cartons to pack 338 soap bars.

Question 2:

Manpreet wants 1500 sacks of cement for making a house. A truck carries 250 sacks at a time. How many trips will the truck make?

A driver charges Rs 500 for a trip. How much will Manpreet pay the driver for all the trips?

Answer:

Total number of sacks of cement needed by Manpreet for making a house = 1500 Number of sacks carried by the truck in 1 trip = 250 Number of sacks carried by the truck in 2 trips = 250 × 2 = 500 Number of sacks carried by the truck in 3 trips = 250 × 3 = 750 Number of sacks carried by the truck in 4 trips = 250 × 4 = 1000 Number of sacks carried by the truck in 5 trips = 250 × 5 = 1250 Number of sacks carried by the truck in 6 trips = 250 × 6 = 1500 ∴ Number of trips made by the truck to carry 1500 sacks = 1500 ÷ 250 = 6 Thus, the truck will make 6 trips to carry 1500 sacks of cement.

Amount charged by the driver for one trip = Rs 500 Number of trips made by the truck = 6 ∴ Total amount charged by the driver for 6 trips = Rs 500 × 6 = Rs 3000 Thus, Manpreet will pay Rs 3000 to the driver for all the trips.

Question 4:

Gangu’s Sweets Gangu is making sweets for Id. He has made a tray of 80 laddoos.

• Are the sweets in the tray enough to pack 23 small boxes? ___________ • How many more sweets are needed? ___________ • Gangu also has a bigger box in which he packs 12 laddoos. How many boxes does he need for packing 60 laddoos?

Answer:

• Total number of laddoos = 80

Number of laddoos in one box = 4 Now Rabiya needs 23 small boxes of laddoos. Number of laddoos in 23 boxes = 4 × 23 = 92 There are only 80 sweets in the tray, which are not enough to pack 23 small boxes.

• Number of sweets now required = 92 − 80 = 12 Thus, 12 more sweets are needed to pack 23 small boxes.

• Number of laddoos Gangu packs in one box = 12 Total laddoos to be packed = 60 Number of boxes required = 60

÷12 = 5 Thus, Gangu needs 5 boxes to pack 60 laddoos.

Answer:

(a) Total money with Razia = Rs 500 Razia wants a change for Rs 500 in the form of 100 rupee notes. Number of 100 rupee notes that Razia will get = 500 ÷ 100 = 5 (b) Total money with Razia = Rs 500 Razia wants a change for Rs 500 in the form of 50 rupee notes. Number of 50 rupee notes that Razia will get = 500 ÷ 50 = 10 (c) Total money with Razia = Rs 500 Razia wants a change for Rs 500 in the form of 20 rupee notes. Number of 20 rupee notes that Razia will get = 500 ÷ 20 = 25 (d) Total money with Razia = Rs 500 Razia wants a change for Rs 500 in the form of 5 rupee notes. Number of 5 rupee notes that Razia will get = 500 ÷ 5 = 100
