# If 40 is subtracted from 60% of a number, the result is 50. Find the number.

In mathematics, a percentage is a number or ratio that is represented in terms of 100.

## Answer: The number is 150.

Let us find the number by using a mathematical expression.

**Explanation:**

Let the unknown number be 'x'.

60% of the number 'x' is expressed mathematically as (60/100) × x

Now let's use the condition given in the question:

40 is subtracted from 60% of x, that is:

60% of x - 40 = [(60/100) × x] - 40

Since the result is equal to 50, therefore, the equation is framed as:

[(60/100) × x] - 40 = 50

or, (60/100) × x = 50 + 40

or, 60x/100 = 90

or, x = 9000/60 = 150

### Therefore, the required number is 150.
