# 15 Most Important circle Problems of Reasoning for different competitive Exams

## Problem # 1

Add all the numbers in every circle except middle number then divide it with 3 to get middle number.

{ 13 + 10 + 7 + 9 } / 3 = 39 / 3 = 13 ( Middle number in 1st picture)

{ 27 + 23 + 5 + 8 } / 3 = 63 / 3 = 21 ( Middle number in 2nd picture)

{ 35 + 44 + 9 + 8 } / 3 = 96 / 3 = 32 ( Middle number in 3rd picture)

**Hence option (1) is right answer.**

## Problem # 2

Multiply both the numbers in the second line then divide it with difference of the numbers in the 1st line of every figure. In last step add "7" to it to get the number in the middle of every figure.

{ ( 9 * 6 ) / ( 13 -10 ) } + 7 = ( 54 / 3 ) + 7 = 18 + 7 = 25 ( Middle number in 1st picture )

{ ( 8 * 3 ) / ( 27 - 23) } + 7 = ( 24 / 4 ) + 7 = 6 + 7 = 13 ( Middle number in 2nd picture )

{ ( 11 * 9 ) / ( 44 - 35 ) } + 7 = ( 99 / 9 ) + 7 = 11 + 7 = 18 ( Middle number in 3rd picture ).

**Hence option (4) is right answer.**

## Problem # 3

This figure consist of four sectors and every sector consists of three numbers. Every number in the inner part of each sector is H C F ( Highest Common Factor ) of two other numbers, which are in outer part of each sector.

HCF of 12 and 27 = 3HCF of 16 and 24 = 8

HCF of 2 and 3 = 1

## Similarly HCF of 4 and 8 = 4 ( The value of question mark )**Hence option (1) is right answer.**

**Hence option (1) is right answer.**

**Problem # 4**

This figure consist of four sectors and every sector consists of three numbers. Every number in the inner part of each sector is HCF ( Highest Common Factor ) of two other numbers which are in outer part of each sector.

H C F of 12 and 15 = 3

H C F of 6 and 4 = 2

H C F of 3 and 2 = 1

H C F of 12 and 6 = 6 ( The value of question mark)

**Hence option (4) is right answer.**

**Problem # 5**

## This figure consist of four sectors and every sector consists of three numbers. Every number in the inner part is LCM ( Lowest Common Multiple ) of two other numbers which are in outer part of each sector.LCM of 12 and 15 = 60 LCM of 9 and 6 = 18LCM of 3 and 2 = 6 LCM of 8 and 6 = 24 (The value of question mark)**Hence option (4) is right answer.****
**

**Hence option (4) is right answer.**

** Problem # 6**

All the Numbers except one in both the circles are written in same pattern . If we

__all the three digits of any number in both the circles then we shall get same result except in one number in both the circles. And that different result will be the odd one out in this problem.__**multiply****In 1st circle**

The product of digits of number 262 = 2 * 6 * 2 = 24

The product of digits of number 226 = 2 * 2 * 6 = 24

The product of digits of number 423 = 4 * 2 * 3 = 24

The product of digits of number 333 = 3 * 3 * 3 = 27 ( Odd one out)

The product of digits of number 342 = 3 * 4 * 2 = 24

**In 2nd circle**

The product of digits of number 562 = 5 * 6 * 2 = 60

The product of digits of number 345 = 3 * 4 * 5 = 60

The product of digits of number 543 = 5 * 4 * 3 = 60

The product of digits of number 256 = 2 * 5 * 6 = 60

The product of digits of number 452 = 4 * 5 * 2 = 40 ( Odd one out)

So from both these circles two results 27 and 40 of numbers 333 and 452 are different from other.

**Hence option (3) is right answer.**

**Problem # 7**

All the Numbers except one in both the circles are written in same pattern . If we

__all the three digits of any number in both the circles then we shall get same result except in one number in both the circles. And that different result will be the odd one out in this problem.__**add****In 1st circle**

The sum of digits of number 163 = 1+ 6 + 3 = 10

The sum of digits of number 145 = 1 + 4 + 5 = 10

The sum of digits of number 334 = 3 + 3 + 4 = 10

The sum of digits of number 441 = 4 + 4 + 1 = 9 ( Odd one out)

The sum of digits of number 343 = 3 + 4 + 3 = 10

**In 2nd circle**

The sum of digits of number 414 = 4 + 1 + 4 = 9

The sum of digits of number 333 = 3 + 3 + 3 = 9

The sum of digits of number 444 = 4 + 4 + 4 = 12 ( Odd one out).

The sum of digits of number 504 = 5 + 0 + 4 = 9

The sum of digits of number 108 = 1 + 0 + 8 = 9

So from both these circles two results 9 and 12 of numbers 441 and 444 are different from other.

**Hence option (2) is correct answer.**

## Problem # 8

In this circle all the numbers are written in a line and the sum of each line is 25. Starting from the line which is right side of ? ( Question mark),

4 + 11 + 3 + 7 = 25

10 + 1 + 9 + 5 = 25

11 + 6 + 2 + 6 = 25

? + 5 + 5 + 8 = 25

⇒ ? + 18 = 25

? = 25 - 18 = 7

**Hence option (1) is correct answer**

## Problem # 9

Here 1st circle consist of

**four**numbers and if we divide sum of all the digits in its outer part with total numbers then result will be the middle number.( 3 + 8 + 7 + 2 )/4 = 20/4 = 5 ( Middle number)

2nd circle consist of

**five**numbers and if we divide sum of all the digits in its outer part with total numbers then result will be the middle number.( 6 + 4 + 8 + 5 + 7 )/5 = 30/5 =6 ( Middle number)

3rd circle consist of

**six**numbers and if we divide sum of all the digits in its outer part with total numbers then result will be the middle number.( 9 + 7 + 8 + 9 + 7 + 8 )/6 = 48/6 =8 ( Middle number)

**Hence option (2) is correct answer**

**Problem # 10**

## This figure consist of four sectors and every sector consists of three numbers. Every number in the inner part is __cube__ of difference of two other numbers which are in outer part of each sector.Cube of ( 8 - 5 ) = 3³ = 27 Cube of ( 23 - 19 ) = 4³ = 64Cube of ( 3 - 2 ) = 1³ = 1Cube of ( 26 - 24 ) = 2³ = 8 ( The value of question mark)**Hence option (4) is correct answer**

__cube__of difference of two other numbers which are in outer part of each sector.

**Hence option (4) is correct answer**

## Problem # 11

## This figure consist of four sectors and every sector consists of three numbers. Every number in the inner part is __ Four times of square of difference of two other numbers__ which are in outer part of each sector.4 × Square of ( 11 - 8 ) = 4 × (3)² = 4 × 9 = 36 4 × Square of ( 5 - 5 ) = 4 × (0)² = 4 × = 0 4 × Square of ( 7 - 3 ) = 4 × (4)² = 4 × 16 = 64 4 × Square of ( 8 - 2 ) = 4 × (6)² = 4 × 36 = 144 ( The value of question mark)**Hence option (1) is correct answer**

__Four times of square of difference of two other numbers__which are in outer part of each sector.

**Hence option (1) is correct answer**

**Problem # 12**

## This figure consist of four sectors and every sector consists of three numbers. Every number in the inner part is cube of difference of two other numbers which are in outer part of each sector.Cube of (11 - 8 ) = 3³ = 27 Cube of ( 5 - 4 ) = 1³ = 1Cube of ( 7 - 3 ) = 4³ = 64Cube of ( 8- 2 ) = 6³ = 216 ( The value of question mark)**Hence option (1) is correct answer****
**

**Hence option (1) is correct answer**

**Problem # 13**

This figure consist of four sectors and every sector consists of three numbers. Every number in the inner part is

( 6 × 3 ) × 5 = 18 × 5 = 90**five times**of product of two other numbers which are in outer part of each sector.( 2 × 3 ) × 5 = 6 × 5 = 30

( 4 × 2 ) × 5 = 8 × 5 = 40

( 5 × 4 ) × 5 = 20 × 5 = 100 ( The value of question marks ) .

**Hence option (1) is right answer.**

**Problem # 14**

This figure consist of four sectors and every sector consists of three numbers. Every number in the inner part is

24 + 11 = 35 ( The number opposite to both 24 and 11 ) . **the sum**of two other numbers which are in outer part of**sector to these numbers.**__opposite__13 + 26 = 39 ( The number opposite to both 246and 13 ) .

9 + 25 = 34 ( The number opposite to both 9 and 25 ) .

7 + ? = 35 ( The number opposite to both 7 and ? ) .

So if we put ? = 28 then we shall have total equal to 35.

**Hence option (2) is right answer**

**Problem # 15**

All the Numbers except one in both the circles are written in same pattern . If we

__all the three digits of any number in both the circles then we shall get same result except in one number in both the circles. And that different result will be the odd one out in this problem.__**multiply****In 1st circle**
