Answer 2

Given:

45% of X is Y

To find:

If 45% of X is Y, then Y% of 45 is equal to

Solution:

From given, we have,

45% of X is Y

⇒ 45% of X = Y

⇒ 45% × X = Y

⇒ 45/100 × X = Y

∴ Y = 45X/100

Now consider,

Y% of 45

(45X/100)% of 45

(45X/100) / 100 × 45

20.25% of X

Therefore, option c. 20.25% of X is correct.
