-  Let 0.25% of a = 0.04. Then , 0.25 x  a/100 = 0.04
     
a= [(0.04 x 100)/0.25] = 16

Percentage is a way of expressing a number as a fraction of 100.It can also be expressed as a decimal value.

To find the missing figure in the given problem, we will use the formula for percentage:

Percentage = (Part/Whole) × 100

Now, in the given problem, part is 0.04 and whole is unknown.

Therefore, Percentage = (0.04/x) × 100

Given that the percentage is 0.25%, we can write 0.25 as a fraction:

0.25 = 25/100

Substituting in the above equation, we get

(0.04/x) × 100 = (25/100)

Cross multiplying, we get

0.04 × 100 = 25 × x

Solving for x, we get

x = 0.04/25 = 0.16

Therefore, the missing figure is 16.

Hence, the correct answer is Option D - 16.
