Question

5. If we add 4 to the numerator of the fraction and increases denominator by 50% then both become equal. And when the numerator is increased by 5 and denominator is doubled then it becomes equal to the original fraction. What will be two times of that fraction?
​

Answer 1

Answer:

Let numerator be x and denominator be y.

Now, x+4=y*1.5. (As increase by 50% = 1.5 times)

Also x/y = (x+5)/(2y)

eliminate y from both sides, which leads to

x = (x+5)/2,

Therefore, x = 5

Now put value of x in first equation,

5+4=y*1.5

Therefore, y = 6.

Hope this clarifies.
