A) x^2/20
B) x^2/10
c) x^2/100
D) 20/x^2
please show me the opinion and logic.......

Answer 1

x% of x is basically x^2/100.
Now, let x^2/100 be 20% of y, where y is the answer we're looking for.
We have: x^2/100 = 20% * y = y/5, which gives us y = x^2/20. Answer: A

Answer 2

\[\large \frac{x}{100} \times x =\frac{20}{100} \times y \implies x^2 = 20y \implies y = \frac{x^2}{20}\]

Answer 3

oh.... yes.. I got it.... thanku guyz
