Question

The sum of numerator and denominator of a fraction is 12 if the denominator is increased by b3 the fraction become ½ then the fraction
​

Answer 1

Let the required fraction be x/y

​

Then,

x+y=12 .......(1)

And,

X/(y+3) = 1/2

​

2x−y=3 .......(2)

On adding 1 and 2, we get,

x=5

On putting x=5 in equation 1, we get,

y=7

THEREFORE THE REQUIRED FRACTION IS 5/7.
