If the numerator of a fraction is increased by 300% and the denominator is increased by 500% , the resultant fraction is `(5)/(12)` . What is the original fraction ?

Options

A. `(8)/(5)`
B. `(5)/(11)`
C. `(12)/(5)`
D. None of these

Answer

D

Explanation

(d) Let the original fraction be `(x)/(y)`
According to the question
`( x xx 400)/(y xx 600)=(5)/(12)`
`implies (x)/(y)=(5)/(12)xx(6)/(4)=(5)/(8)`
