ANSWERS:

1. 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.
2. 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)
3. 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.
4. 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)
5. 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)
6. 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.
7. 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.
8. 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.
9. 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.
10. 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.
