Question
Who might be sitting between C and G, if there is only
person between them? Eight friends A, B, C, D, E, F, G and H are sitting around a square table facing the centre. i. B is facing D and is sitting to the right of E. ii. F, who is a neighbour of D, is facing G. iii. There are two persons between C and H, and H is not facing E.Solution

If a and b are the roots of x² + x – 2 = 0, then the quadratic equation in x whose roots are 1/a + 1/b and ab is
Solve the quadratic equations and determine the relation between x and y:
