Answer 2

Answer:

Required number is 5.

Option b is the correct answer.

Step-by-step explanation:

Given a number increased by 20 and then reduced by 15 becomes 10.

Let the number be x.

Now this number increased by 20.

So it becomes $x + 20$

Then it reduced by 15

So now the number $x + 20 - 15 = x + 5$

According to question,

$x + 5 = 10$

we are separating variable and constant part and get,

$x = 10 - 5$

Here we are subtracting 5 from 10,

$x = 5$

Therefore the number is 5.
