When 24 is subtracted from a number, it reduces to 60%. The two-fifth of that number is:

Correct option is C

Given:

When 24 is subtracted from a number, it reduces to 60%

Solution:

Let the number be x

Then according to question:

​$$x -24 = 60\% of x$$​​

​$$x -24 = \frac{3x}{5}$$​​

​$$x - \frac{3x}{5} =24$$​​

​$$x= 60$$​​

Number is 60

Now two-fifth of 60 = $$\frac{2}{5}\times 60 = 24$$​​
