If 25% of a number is added to 60, then the result is the same number. 80% of the same number is:

Correct option is D

Given:

25% of a number + 60 = the number

Solution: 

Let the number be x

25% of x = $$\frac {25}{100} × x = \frac x4$$​​

So, 

​$$\frac x4 + 60 = x$$​​

​$$60 = x - \frac x4$$​​

​$$60 = \frac{3x}4$$​​

x = $$\frac{ 60 × 4}3 = 80$$​​

Now,
80% of x = 80% of 80 = $$\frac{80}{100} × 80$$​ = 64
