The denominator of a fraction exceeds its numerator by 3. If one is added to both numerator and denominator, the difference between the new and the original fractions 1 becomes . Find the original fraction.
Let the denominator be ‘(X+3)’, so the numerator will be ‘X’.
the original fraction is
the new fraction is
On simplifying further,
24(3) = X2 + 7X + 12
X2 + 7X – 60 = 0 –––––– (i)
On applying Sreedhracharya formula
∴ X = –12 or 5.
∴ the numerator is X = 5 and denominator (X+3) will be 8 and the fraction will be , as taking (–12) will form a fraction i.e., (not satisfying the conditions) .
