Three particles A, B and C are projected from the same point with the same initial speeds making angles 30^(@), 45^(@) and 60^(@) respectively with the horizontal. Which of the following statement is correct?

Two particles projected form the same point with same speed u at angles of projection alpha and beta strike the horizontal ground at the same point. If h_1 and h_2 are the maximum heights attained by the projectile, R is the range for both and t_1 and t_2 are their times of flights, respectively, then

Two projectiles A and B are projected with same speed at an angle 30^(@) and 60^(@) to the horizontal, then which of the following is not valid where T is total time of flight, H is max height and R is horizontal range.
