Q3: Octopus has 8 legs, then how many legs altogether do 7 octopuses have?
Ans: Given, the Number of legs in one octopus = 8.
The number of octopuses = 7.

Q4: If a spider has 8 legs, So how many total legs for 3 spiders?
Ans: Here, one spider has 8 legs.
Total number of spiders = 3
Then, the total number of legs for 3 spiders = (8 + 8 + 8)
= 3 x 8 = 24
Therefore, the total number of legs for 3 spiders is 24.

Q5: Find the missing number in 100, 104, 108, ……., 116, 120.
Ans: The difference between 104 and 100 is 4, likewise between 108 and 104 is 4. So, we can say that in every step the number is increased by 4. Therefore the pattern is the difference between two consecutive numbers is 4 and hence the next number after 108 is ( 108 + 4 ) = 112.
Therefore the required pattern is
100 , 104 , 108 , 112, 116 , 120.

Q6: How many different arrangements are possible for 24 sticks.
Ans: To find possible stick arrangements in 24 sticks. First, you need to find all possible multiples of 24: 2, 4, 6, 8, 12, 24.
Possible arrangements 212, 38, 64, 122, 83, 46.
