we know that 1/4 means 0.25.

it's given that 0.01%= 0.01/100
=(1/100)/100
=1/10000
= 0.0001

now we can calculate the task = 0.25 * 0.0001
= 0.000025

thus option A is the correct answer.

What is wrong with below logic:

1/4 of 100% = 25
1/4 of 10%. = 2.5
1/4 of 1%. = 0.25
1/4 of 0.1%. = 0.025
1/4 of 0.01%. = 0.0025 which is option C.

I am bit confused if percent plays a role in moving the digit further by 2 decimals? Which gives result option 0.000025 (Option-A)

To solve this kind of questions one has to master skills of translation words => math

Which of the following is equal to $$\frac{1}{4}$$ of $$0.01$$
(wich) X (is equal) = 1/4 (of)* 0.01 (percent) *1/100
x=0.000025

praveenbaranwal , yes, you are a little mixed up about percent here.
Percent means "per 100" --
which means divide by 100 --
move the decimal two places to the left (add zeros).

1/4 of 100% = 25 (incorrect)
Percent is used oddly here.
But 1/4 of 100%?
(1/4 * 100/100)=100/400=1/4=.25
1/4 of 100 percent is 25 PERCENT

1/4 of 100=(1/4*100)=(100/4) = 25
25% of 100 =(25/100 * 100) = 25
.25 of 100 = 25
$$\frac{1}{4} = .25$$, and
.25 is the decimal expression for 25%

I think you've just gotten mixed up.

.01 PERCENT = $$\frac{.01}{100}$$
We don't want decimals in the numerator. We multiply by 100/100 to get rid of the decimal
So that fraction becomes
$$\frac{1}{10000}$$, which = .00001
1/4 = .25

(0.25)*(0.00001) = .000025

As I said, I think you've just gotten mixed up. It happens. No big deal. The two links below will get you sorted out.

Hope that helps.

0.01 % = 0.01/100 = 0.0001

$$\frac{0.0001}{4} = .000025$$
