Let numerator of the fraction is X and denominator is Y, then fraction will be X/Y.
Numerator increased 200%, so new numerator would be,
[X + (200 of X)/100] = 3X - - - - - - - - - - - - - - - - - - - - - - - - - - - - - (1)
New denominator,
[Y + (350Y)/100 ] = 45Y/10 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - (2)
Now, accordibng to question,
3X /(45Y/10) = 5/12
30X / 45Y = 5/12
360X = 225Y
X/Y = 225/360
X/Y = 5/8
So, Original fraction was 5/8.
