A, B, C, D, E, F, G and H are standing in a row facing North.
B is not neighbour of G.
F is to the immediate right of G and neighbour of E.
G is not at the extreme end.
A is sixth to the left of E.
H is sixth to the right of C.Which one of the following is correct in respect of the above?
(a) C is to the immediate left of A.(b) D is immediate neighbour of B and F.(c) G is to the immediate right of D.(d) A and E are at the extreme ends.2. In a school, there are five teachers A, B, C, D and E. A and B teach Hindi and English. C and B teach English and Geography. D and A teach Mathematics and Hindi. E and B teach History and French. Who teaches maximum numb, of subjects?(a) A(b) B(c) D(d) E3. What is the total number of digits printed, if a book containing 150 pages is to be numbered from 1 to 150?(a) 262(b) 342(c) 360(d) 4504. A clock strikes once at 1 o’clock, twice at 2 o’clock and thrice at 3 o’clock, and so on. If it takes 12 seconds to strike at 5 o’clock, what is the time taken by it to strike at 10 o’clock?(a) 20 seconds(b) 24 seconds(c) 28 seconds(d) 30 seconds5. Consider the given statement and the two conclusions that follow:Statement:Morning walk is good for health.Conclusions:
All healthy people go for morning walk.
Morning walk is essential for maintaining good health.
What is/are the valid conclusion/ conclusions?(a) 1 only(b) 2 only(c) Both 1 and 2(d) Neither 1 nor 2ANSWERS1. SolutionB is not neighbour of G, which means final position is as under:
A
C
B
D
G
F
E
H
Now let us check the options:(a) C is to the immediate left of A…..ANSWER(b) D is immediate neighbour of B and F…..NO(c) G is to the immediate right of D……NO(d) A and E are at the extreme ends…..NO2. SolutionSolution:A – Hindi, EnglishB – Hindi, English, Geography, History, FrenchC – English, GeographyD – Mathematics, HindiE – History, French Thus the answer is option (b):3. SolutionFrom 1 to 150, there are9 single digit numbers (1 to 9) + 90 two digit numbers (10 to 99) + 51 three digit numbers (100 to 150)Thus total digits to be printed = (9 × 1) + (90 × 2) + (51 × 3) = 342. Therefore the answer is option (b):(b) 3424. SolutionThe clock will strike 3 times at 3 o’ clock. These five strikes are interspersed with four intervals as under:Strike – Strike – Strike – Strike – StrikeIt is these intervals that take time. When clock strikes 5 times, there are 4 intervals. Total time taken by them is 12 seconds. Thus each interval is of duration 3 seconds.When the clock will strike 8 times at 9 o’ clock there shall be 8 such intervals and thus time taken shall be 8 ×3 = 24 seconds.(b) 24 seconds5. SolutionThe statement simply says that morning walk is good for health. It is not presented as either the necessary or the suffcient condition for good health.Hence, conclusion 1 is incorrect as all healthy people need not go for morning walkSimilarly, conclusion 2 is also incorrect as morning walk is not an esssential condition for good healthHence, the correct answer is option (d)
