A) \[5/8\]
B) \[8/5\]
C) \[3/5\]
D) \[4/7\]
Correct Answer: A
Solution :
[a] Let the denominator and numerator of the fraction be x and y respectively. |
According to the question, |
\[x+y=13\] ...(1) |
and \[x-y=3\] ...(2) |
On adding eqs. (1) and (2), we get |
\[2x=16\,\,\,\,\,\,\,\,\,\,\Rightarrow \,\,\,\,\,\,x=8\] |
From eq. (1), we get y=13-8=5 |
\[\therefore \] Required fraction is\[\text{5}/\text{8}\]. |
