Understanding the Groups
To determine which group the number 18 belongs to, we need to analyze each option:
Option A: 2, 2, 4, 8...
- This sequence consists of powers of 2.
- The numbers are: 2^1, 2^1, 2^2, 2^3, etc.
- Since 18 is not a power of 2, it does not belong here.
Option B: 2, 3, 6...
- This sequence is comprised of the multiples of 3.
- The numbers can be expressed as: 3*1, 3*2, 3*3, etc.
- Since 18 is equal to 3*6, it fits perfectly into this group.
Option C: 3, 3, 9, 27...
- This sequence represents powers of 3.
- The numbers are: 3^1, 3^1, 3^2, 3^3, etc.
- As 18 is not a power of 3, it does not belong to this group.
Option D: 2, 5, 10...
- This sequence consists of numbers that do not follow a clear mathematical pattern relating to 18.
- The numbers do not connect to multiples or factors of 18.
Conclusion
- After analyzing all groups, we can clearly see that 18 is a multiple of 3, making option B (2, 3, 6...) the correct choice.
- Therefore, the answer to which group 18 belongs to is option B.

Identifying the Group and the Odd One Out
Group: 3, 7, 9, 12, 21, 27
Odd One Out: 7
Explanation
In this group, all numbers are odd except for 12, which makes it a possible odd one out. However, the number 12 is also divisible by 3, which is a common factor among the other numbers in the group. Therefore, the number 12 is not the odd one out.
Looking at the other numbers, we can see that 3, 9, 21, and 27 are all multiples of 3, while 7 and 12 are not. This makes 7 the odd one out as it does not have the common factor of being a multiple of 3, which the other numbers in the group have.
Therefore, the correct answer is option D, 7.

10
c)
12
d)

 | Pankaj Saha answered |
Solution:
Given, 3 groups of 16 balls were divided into 6 equal groups of 4.
Total number of balls = 3 × 16 = 48
Number of groups formed = 6
Number of balls in each group = 4
Number of balls in 6 groups = 6 × 4 = 24
Remaining number of balls = 48 - 24 = 24
Let the remaining balls be divided into 2 groups of x balls each.
Total number of balls = Sum of balls in both the groups
24 = x + x
24 = 2x
x = 12
Therefore, the remaining balls can be divided into 2 groups of 12 balls each. Hence, the correct option is (c) 12.

Total number of balls = 3 × 16 = 48
Number of groups formed = 6
Number of balls in each group = 4
Number of balls in 6 groups = 6 × 4 = 24
Remaining number of balls = 48 - 24 = 24
Let the remaining balls be divided into 2 groups of x balls each.
Total number of balls = Sum of balls in both the groups
24 = x + x
24 = 2x
x = 12
Therefore, the remaining balls can be divided into 2 groups of 12 balls each. Hence, the correct option is (c) 12.

Which of the following is non symmterical A, I , T, O, H, L
a)
A
b)
I
c)
L
d)
H
 | Subset Academy answered |
- All given letters except L have vertical mirror symmetry.
- A, I, T, O and H look the same on either side of a central vertical line.
- L’s two strokes are unevenly placed, so its left and right halves don’t match.
- Therefore, L is the only non-symmetrical letter in the group.

Understanding the Grouping of Numbers
To determine the best suitable grouping for the numbers 1, 5, 8, 2, 3, and 4, we need to analyze the options provided.
Analyzing the Options
- Option a: (1, 2, 3) and (5, 4, 8)
- Group 1: {1, 2, 3} → Contains lower numbers.
- Group 2: {5, 4, 8} → Contains one higher number (8) and two mid-range numbers (5, 4).
- Option b: (1, 5, 8) and (2, 4, 3)
- Group 1: {1, 5, 8} → Mixed group with low and high values.
- Group 2: {2, 4, 3} → Slightly balanced but lacks a clear distinction.
- Option c: (1, 3, 5) and (2, 4, 8)
- Group 1: {1, 3, 5} → Low to mid-range numbers.
- Group 2: {2, 4, 8} → A mix of lower and higher values with a clear separation.
- Option d: (2, 1, 4) and (5, 3, 8)
- Group 1: {2, 1, 4} → Contains low values.
- Group 2: {5, 3, 8} → More high-end numbers.
Why Option C is the Best
- Balanced Distribution:
- Option c has a clear distinction between low/mid-range numbers and a mix of low/high numbers.
- Range Representation:
- The first group represents lower values effectively, while the second group shows a good spread of higher values.
- Logical Grouping:
- It groups numbers in a way that reflects their relative sizes, maintaining a useful balance.
In conclusion, option c is the best choice as it offers a logical and balanced grouping of the numbers provided.

 | Varsha verma answered |
Understanding the Problem
When we have 50 bananas and want to divide them into 6 groups, we need to perform a simple division to find out how many bananas will be in each group and how many will be left over.
Calculating the Division
To find out how many bananas each group gets, we divide:
- Total bananas: 50
- Number of groups: 6
Performing the Division
- When we divide 50 by 6, we calculate:
- 50 ÷ 6 = 8 (this is the number of bananas in each group)
- Now, we multiply back to find out how many bananas are used:
- 8 bananas/group × 6 groups = 48 bananas used
Finding the Remainder
Next, we need to find out how many bananas are left after distributing them:
- Total bananas: 50
- Bananas used: 48
Calculating Leftovers
- Leftover bananas = Total bananas - Bananas used
- Leftover bananas = 50 - 48 = 2
Conclusion
After dividing 50 bananas into 6 groups, there are 2 bananas left over. Thus, the correct answer is option 'B' (2).
This simple division shows how many bananas can evenly be distributed among the groups and highlights the concept of remainders in division.
