Question
Two trains X and Y start at the same time in the
opposite direction from two points P and Q and arrive at their destinations 25 and 16 hours respectively after their meeting each other. At what speed does the second train Y travel if the first train travels at 48 km/h.ÂSolution
Let the speed and time of two trains be s1 and s2, and t1 and t2. s1/s2 = (t2/t1)1/2 => 48/s2 = 4/5 => s2 = 60 km/hr.
Statements: J < K = L ≥ M ≥ P; F ≥ K < G
Conclusion I. J < G II.F ≥ P
...Statement: T > U = V < W > X; Y ≤ H < S; X > Z > S
Conclusions:
I. W > Y
II. Y < Z
III. U < Z
What should come in the place of question mark, in the given expressions to make ‘D > F’ always true?
P > D ≥ I _?_ J = F > M
Statements: Z > X = A ≥ V > W > B; B = Y ≥ U = E > T
Conclusions:
I. Z > U
II. Y > Z
