Question
What is the speed of a boat in still water?
Statement I:  The boat covers a distance of 120km in 5 hours while running upstream. Statement II:  It covers the same distance in 3 hours while running downstream. Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer:Solution
From I and II Let the speed of the boat be x km/hr Speed of the stream be y km/hr ∴ Speed of upstream x – y = 120/5 = 24……(i) Speed downstream x + y = 120/3 = 40        …….(ii) From eq. (i) and (ii), we get x = 32 km/hr and y = 8 km/hr
Statements: U > H ≥ W; S > T ≥ B; S < H; C ≤ D = U
Conclusions:
I. D > B
II. T < U
III. W ≤ D
Statements: X > O > D; T > M ≥ O; X > R
Conclusions:
I. T > R
II. R < DStatements: E $ N, N * G, H % E
Conclusions: a) G # H Â Â Â b) H $ N

Conclusions:
I) P < Y
II) R ≥ N
In these questions, relationship between different elements is shown in the statements. The statements are followed by conclusions.
