change the option, it's wrong (Question: 128774.0 )

how 3/4 and 1/3 can be same?

Question:
If the numerator of a fraction is increased by 200% and the denominator is increased by 400%, the resultant fraction is 1 \(\cfrac{1}{20}\). What was the original fraction?
Options:
A) 1 \(\cfrac{3}{4}\)
B) \(\cfrac{11}{10}\)
C) \(\cfrac{6}{5}\)
D) 1 \(\cfrac{1}{2}\)
E) None of these
Solution:
Ans: (a) Let fraction be \(\cfrac{x}{y}\)

\(=\cfrac{x+2x}{y+4y}= \cfrac{21}{20} ⇒ \cfrac{x}{y} = \cfrac{7}{4} = 1 \cfrac{3}{4}\)
