To Find
Find the number.

Let the number be x.
According to Question:
2x - 8 = 16
2x = 16 + 8
2x = 24
x = 8/2
x = 12
So, the number is 4.
Answer 2
Given
A number exceeds two-fifths of it by 36.
To Find
Find the number.
Solution
Let the number be x
According to Question
x - 2/5x = 36
5x - 2x / 5 = 36
3x / 5 = 36
3x = 36 × 5
3x = 180
x = 180/3
x = 60
So, the number is 60.
