Question

The sum of 2 consicutive no is 38. find the number​

Answer 1

Answer:

18.5 and 19.5 is the correct answer

Step-by-step explanation:

Sum = 38

Let the no. = x

let another no. = x + 1

x + x + 1= 38

2x + 1 = 38

2x = 38 -1

2x = 37

x = 37 /2

x = 18.5

One no. is 18.5

Another no. = x + 1

= 18.5 + 1

= 19.5

Answer 2

Question:

The sum of two consecutive even numbers is 38. Find the numbers.

Answer:

The required numbers are 18 & 20.

Step-by-step-explanation:

Let the first number be x.

And the consecutive even number be ( x + 2 ).

From the given condition,

x + ( x + 2 ) = 38

⇒ x + x + 2 = 38

⇒ 2x + 2 = 38

⇒ 2x = 38 - 2

⇒ 2x = 36

⇒ x = 36 ÷ 2

⇒ x = 18

Now,

The first number = x = 18

And the consecutive even number = ( x + 2 ) = ( 18 + 2 ) = 20

∴ The required numbers are 18 & 20.
