Q.1 In a triangle the sum of two sides is x and the product of the same two sides is y. If x2 - c2 = y, where c is the third side of the triangle, then the ratio of the in-radius to the circum-radius of the triangle is
  $\frac{3y}{2x\left (x + c \right )}$
  $\frac{3y}{2c\left (x + c \right )}$
  $\frac{3y}{4x\left (x + c \right )}$
  $\frac{3y}{4c\left (x + c \right )}$
