Question

If one tenth of a number is added to 2. the result is half of that number. what is the number?​

Answer 1

5

Explanation:

According to the given question, the calculation of number is shown below:-

Let the number be x.

`(1)/(10)` of x will be added to the number of 2, so that the result is half of x.

`2 + (1)/(10) x = (1)/(2) x`

Now we will solve the above equation

`2=(1)/(2) x-(1)/(10) x\\\\2=(2x)/(5)\\\\10=2x\\\\(10)/(2) =x\\\\`

x = 5

Therefore the correct answer is 5

Hence, the number based on the given information provided in the question is 5
