Fill in the blanks to make the statements true.

If a number is increased by 20, it becomes 45. Then the number is ________.

Let the number be x.


If it is increased by 20, it becomes (x + 20),


So, the equation formed is x + 20 = 45


⇒ x = 45 – 20 [transposing 20 to RHS]


⇒ x = 25


Hence, the number is 25.
