The numerator of a fraction is 1 less than twice the denominator. If the numerator and denominator are both increased by 1, the fraction becomes 4/5. Find the fraction? Choose the correct choice from the following options
A) A)2/3
B) B)3/5
C) C)7/4
D) D)5/9
E) of these
Let the numerator and denominator of the fraction be 'n' and 'd' respectively.   n = 2d - 1   (n + 1)/(d + 1) = 4/5   5n + 5 = 4d + 4   5(2d-1) + 5 = 4d + 4 =&gt; d = 4   n = 2d - 1 =&gt; n = 7   Hence the fraction is : 7/4   ANSWER:7/4
