ANSWERS:

- Number of legs Gayatri counted = 28 legs

A cat has 4 legs.

8 legs means 2 cats are there.

12 legs means 3 cats are there.

If we are counting this way 28 legs means 7 cats are there.

Therefore there are 7 cats in the box. - Number of legs counted by Billo = 28 legs

A chicken has 2 legs.

Therefore, number of chickens in the box = 14. (Since 14 x 2 = 28) - Number of days in a week = 7 days

3 weeks are there in 21 days because 3 x 7 = 211.

Therefore, for 3 weeks she has away from school. - Jumps taken by frog to cover 3 steps = 1

a) Jumps taken by frog to reach 27 = 9 jumps (Because 3 x 9 = 27)

b) He has taken 12 jumps, if he is at 36. (Because 3 x 12 = 36)

c) If he is at 42, he has taken 14 jumps. (Because 3 x 14 = 42) - Jumps taken by rabbit to cover 5 steps = 1

a) Number of jumps needed to reach 25 = 5 (Because 5 x 5 = 25)

b) He reaches 40 after taking 8 jumps. (Because 5 x 8 = 40)

c) He needs 11 jumps to reach 55 (Because 5 x 11 = 55) - Number of sea shells required to make a necklace = 17

Number of sea shells required to make 2 necklace = 34

(Because 2 x 17 = 34)

Number of sea shells required to make 3 necklace= 51

(Because 3 x 17 = 51)

Number of sea shells required to make 4 necklace = 68

(Because 4 x 17 = 68)

Number of sea shells required to make 5 necklace = 85

(Because 5 x 17 = 85)

Therefore, 5 necklaces can be made by using 100 sea shells and 15 sea shells will be remained. - Number of soap bars that can hold one carton = 85

Number of soap bars that can hold two cartons = 85 x 2 = 170

Number of soap bars that can hold three cartons = 85 x 3 = 255

Number of soap bars that can hold four cartons = 85 x 4 = 340

Number of cartons required to pack 338 soap bars = 4 cartons. - a) Number of sacks needed for making a house = 1500 sacks

Number of sacks carried by the truck in one step = 250

So number of trips made by the truck to carry 1500 sacks = 6

(Because 6 x 250 = 1500)

b) Amount charged for one trip = Rs 500

Amount paid by Manpreet for all the trips = 500 x 6 = 3000 rupees. - a) Number of laddoos needed to pack in one small box = 4

Number of laddoos needed to pack in 23 small boxes = 23 x 4 = 92

Number of laddoos in the tray = 80

So it is not enough to pack in 23 small boxes.

b) 12 more sweets are needed.

c) Number of laddoos that can be packed in the bigger box = 12

Number of boxes needed for packing 60 laddoos = 60 divided by 12 = 5 boxes. - Number of story books brought by Neelu = 15

Number of students present in the class = 45

Number of students need to share one book = 45 divided by 15 = 3 students.
