# 10 Reasoning questions with answers for competitive exams

**PROBLEM 1**

__same formula will be applicable__to third figure to find out the value of question mark.

**Formula**:- The Number in each dark box in every figure is H C F ( Highest common Factor) of remaining two numbers.

**Solution:- HCF of two numbers = 3rd number**

H C F of 6 and 10 in 1st figure is 2 (The number in 1st figure of dark square).

H C F of 12 and 36 in 2nd figure is 12 (The number in 2nd figure of dark square).

H C F of 15 and 25 in 3rd figure is 5 (The number in 3rd figure of dark square).

**Option (4)5 is correct option.**

## PROBLEM 2

__same formula will be applicable__to third figure to find out the value of question mark.

**Formula**:- The Number in each dark box in every figure is L C M ( Lowest common Multiple) of remaining two numbers.

**Solution:- LCM of two numbers = 3rd number**

L C M of 6 and 10 in 1st figure is 30 (The number in 1st figure of dark square).

L C M of 12 and 36 in 2nd figure is 48 (The number in 2nd figure of dark square).

L C M of 5 and 7 in 3rd figure is 35 (The number in 3rd figure of dark square).

**Option (2)35 is correct option**

## PROBLEM 3

**1st Row**

**2nd Row**

**3rd Row**

**Option (D)25 is correct option.**

## PROBLEM 4

### This box problem consist of three rows and four columns. And we have to find the value of question mark after studying the pattern of all the numbers in this box. Third row of every column is equal to the product of square root of 1st row and cube root of 2nd row .

Formula :- 3rd row = Square root of 1st row × Cube root of 2nd row

### **1st Column**

**1st Column**

**2nd Column**

**3rd Column**

**4th Column**

**Option (C)42 is correct option**

## PROBLEM 5

In Roman number system C , CC , CCC , D , DC are number which have values in decimal system as follows.

**Option (1)CD is correct option.**

## PROBLEM 6

**each number is written in word and then its letters have been counted to find the sum of two given numbers".**

**ZERO**+

**ZERO**= 4(Four letters in word ZERO) + 6(Four letters in word ZERO) = 8 (Sum of letters in both the words is 8).

**Formula**:- (Half of Square of 1st number) = 2nd number

**2nd Number**

**Option (4)648 is correct option.**

## PROBLEM 8

**Formula**:- Product of two consecutive factors = Any number

**Option (2)110 is correct option.**

## PROBLEM 9

__same formula will be applicable__to third figure to find out the value of question mark.

**Formula**:- Half of the product of two outer numbers in each triangle is equal to third number .

**1st Triangle**

**2nd Triangle**

**3rd Triangle**

**Option (4)21 is correct option.**

## PROBLEM 10

This reasoning problem consists of three figures and every figure have three numbers associated to it . So the solution of this problem is to find the value of question mark using other two numbers associated to it .

__same formula will be applicable__to third figure to find out the value of question mark.

**Formula**:- Sum of two numbers in each triangle is equal to sum of remaining number .

**1st Triangle**

**2nd Triangle**

**3rd Triangle**

( 5 + ? ) = ( 9 + 3 ) = 12

5 + ? = 12

? = 12 - 5

? = 7

**Option (1)7 is correct option.**
