Explanation :-
A fraction becomes 1/3 when 1 is subtracted from the numerator and it becomes 1/4 when 8 is added to its denominator. Find the fraction.
Let us assume the numerator to be =x
Let us assume the denominator to be =y
Hence the fraction becomes=x/y
According To The given condition
(x−1)/y=1/3
⇒y=3x−3 ———-(i)
According To The Second given condition,
x/(y+8)=1/4
⇒y+8=4x
⇒y=4x−8 ————(ii)
Combining(i)and(ii) we get,
3x−3=4x−8
⇒3x−4x=−8+3
−x=−5
⇒x=5
from(i)
y=15−3=12
So,the fraction is =5/12
