If x is an even number, then the consecutive even number is

The largest number of the three consecutive numbers is x + 1. Then, the smallest number is

1. x + 2
2. x + 1
3. x
4. x - 1

The solution of the equation  = 2 is

1. 10
2. 
3. 
4. 

On subtracting 30 from two times a number, we get 56. This statement in the simplified form of an equation is

1. x – 15 = 28
2. 2x + 30 = 56
3. 30 – 2x = 56   
4.  = 56

If 6 is added to 3 times of a number, it becomes 15. This statement in the form of an equation is

1. 3x + 6 = 15
2. 3x – 6 = 15
3. 3x + 15 = 6
4.  = 15

A number, when subtracted from 40, results in 15. This statement in the form of an equation is

1. 40 – x = 15
2. x – 40 = 15
3. 40 + x = 15
4. 40x = 15

The statement ‘on adding 10 to a number, the number becomes 20’ in the form of an equation is

1. x – 10 = 20
2. x + 10 = 20    
3. 10x = 20
4.  = 20

The degree of the equation x² – 2x + 1 = x² – 3 is

1. 1
2. 2
3. 0
4. 3

The linear equation in one variable, x, is

1.  
2. 
3. 
4. x² + 2x + 3 = 0
