Q1. Two trains of 200 m and 100 m long are running parallel at the rate of 20 m/sec. and 22 m/sec. respectively. How much time will they take to cross each other, if the trains are running along the same direction?
Q1. Two trains of 200 m and 100 m long are running parallel at the rate of 20 m/sec. and 22 m/sec. respectively. How much time will they take to cross each other, if the trains are running along the same direction?
Answer: (D) 50 sec
Answer: (D) 50 sec
Answer: (D) 50 sec
The difference of speed = 22m/s - 20m/s = 2m/s
As the train with speed 22m/s will cross the other, hence this train have to go the smallest length of the trains distance ahead of the other to cross completely.
Hence This train will be ahead of 100m with a speed of 2m/s.
Hence The time to cross each other will take = 100m / (2m/s)
= 50 sec
The difference of speed = 22m/s - 20m/s = 2m/s As the train with speed 22m/s will cross the other, hence this train have to go the smallest length of the trains distance ahead of the other to cross completely. Hence This train will be ahead of 100m with a speed of 2m/s. Hence The time to cross each other will take = 100m / (2m/s) = 50 sec
The difference of speed = 22m/s - 20m/s = 2m/s As the train with speed 22m/s will cross the other, hence this train have to go the smallest length of the trains distance ahead of the other to cross completely.

Q3. 5 : 27 :: 9 : ________
Q3. 5 : 27 :: 9 : ________
Fill the blank.
Fill the blank.
Fill the blank.
Answer: (A) 83
Answer: (A) 83
Answer: (A) 83
5 : (52 + 2) = 5 : 27
Hence
9 : (92 + 2) = 9 : 83
5 : (52 + 2) = 5 : 27 Hence 9 : (92 + 2) = 9 : 83
5 : (52 + 2) = 5 : 27 Hence 9 : (92 + 2) = 9 : 83

Q4. AQRD : BRSE :: LMTJ : ________
Q4. AQRD : BRSE :: LMTJ : ________
Answer: (D) MMUK
Answer: (D) MMUK
Answer: (D) MMUK
AQRD : (A+1)(Q+1)(R+1)(D+1) = AQRD : BRSE
LMTJ = (L+1)(M+1)(T+1)(J+1) = LMTJ : MMUK
AQRD : (A+1)(Q+1)(R+1)(D+1) = AQRD : BRSE LMTJ = (L+1)(M+1)(T+1)(J+1) = LMTJ : MMUK
AQRD : (A+1)(Q+1)(R+1)(D+1) = AQRD : BRSE LMTJ = (L+1)(M+1)(T+1)(J+1) = LMTJ : MMUK

Q5. Priya booked a ticket for a movie whose trailer was released 20 days before she booked the ticket. She watched the movie 45 days after the trailer was released. The movie was released 16 day before the day on which Priya watched the movie. On which day of the week was the movie released if she booked the ticket on Sunday?
Q5. Priya booked a ticket for a movie whose trailer was released 20 days before she booked the ticket. She watched the movie 45 days after the trailer was released. The movie was released 16 day before the day on which Priya watched the movie. On which day of the week was the movie released if she booked the ticket on Sunday?
Answer: (D) Tuesday
Answer: (D) Tuesday
Answer: (D) Tuesday
Priya booked the ticket after 20 days of the trailer was released.
She watched the movie 45 days after the trailer was released.
Hence She watched the movie (45-20) = 25 days after booking the ticket.
The movie was released 16 day before the day on which Priya watched the movie.
Hence the movie was released (45-16) = 29 days after the trailer was released.
Hence the movie was released (29-20) = 9 days after booking the ticket.
If she booked the ticket on Sunday then the movie released on Tuesday

Q7. If 20% of a is b, then b% of 20 is the same as :
Q7. If 20% of a is b, then b% of 20 is the same as :
Answer: (A) 4% of a
Answer: (A) 4% of a
Answer: (A) 4% of a
20% of a is b
Hence b = 20% of a = 20a/100
b% of 20
= 20% of b
= (20/100) * 20a/100
= (20*20*a)/(100*100)
= 4a/100
= (4/100) * a
= 4% of a
20% of a is b Hence b = 20% of a = 20a/100 b% of 20 = 20% of b = (20/100) * 20a/100 = (20*20*a)/(100*100) = 4a/100 = (4/100) * a = 4% of a
20% of a is b Hence b = 20% of a = 20a/100 b% of 20 = 20% of b = (20/100) * 20a/100 = (20*20*a)/(100*100) = 4a/100 = (4/100) * a = 4% of a

Answer: (C) 1.2 km
Answer: (C) 1.2 km
Answer: (C) 1.2 km
A starts journey before B at a speed of 1 m/s. Hence A will be ahead of B
(10*60)s * 1m/s = 600m
Let A covers a distance of X after starting of B,
Then X + 600m = 2X
=> 2X - X = 600m
=> X = 600m
Hence B will cover a distance of 2X = 2 * 600m = 1200m = 1.2 km
