If 3 is added to both numerator and denominator of a fraction , it becomes 5/7. If 9 is subtracted from both numerator and denominator, it becomes 1/3. What is the fraction ?
Correct Answer: 12/18
Let, numerator = x, denominator = yfirst condition, x+3y+3 = 57 or, 7x- 5y = -6second condition, x-9y-9 = 13 or, 3x - y = 18Solving the above two equation, we get x = 12 and y = 18So, the required fraction is = 1218 (Ans)
