Three
men and three women are travelling in two
cars (red and blue). Each car has exactly
three persons. The cars cannot have all
women or all men passengers. Mala, Ajit
and Suman know how to drive a car. Mala
and Sapna are women. Manjit and Sarat are
not in the same car. Ajit and Sarat are
men.
Q. No. 1:
If the red car can have either Manjit or Sarat but not both while Ajit drives it and Mala is driving the blue car, which of the following can be true ?
Answer: C The given conditions are – (i) The persons who know how to drive a car are - Mala, Ajit and Suman. Condition-1: At least one person should be in each car who knows driving. (ii) Females are Mala and Sapna and Males are Ajit and Sarat. (iii) Condition-2 Manjit and Sarat are not in the same car. (iv) Condition-3 Each car has three persons and the cars cannot have all women or all men passengers. (v) Condition-4 Each car has exactly three persons. => If Manjit is in red car, Sarat will be in blue car, then Red car ⇒ Manjit, Ajit (M) Blue car ⇒ Sarat (M), Mala (F) There is at least one man (Sarat) and one woman (Mala) in blue car. So, one man and one woman will certainly go in red car. Therefore, ‘Manjit is a woman’ can be a true statement. Similarly, ‘Suman is a man’ can be a true statement. Hence, the answer is option (C). Note: If Manjit goes in a blue car, all the conditions will be satisfied.
Q. No. 2:
If Suman and Manjit are the two passengers in the red car, who can be passengers of the blue car ?
Answer: D The given conditions are – (i) The persons who know how to drive a car are - Mala, Ajit and Suman. Condition-1: At least one person should be in each car who knows driving. (ii) Females are Mala and Sapna and Males are Ajit and Sarat. (iii) Condition-2 Manjit and Sarat are not in the same car. (iv) Condition-3 Each car has three persons and the cars cannot have all women or all men passengers. (v) Condition-4 Each car has exactly three persons. => If Manjit is in red car, then Sarat must be in blue car. So, option B and C is not correct. Again, we need one man or woman who know driving and in Option A there is no driver.

Everyday Miss Yadav, Miss Sharma, Miss Toppo and Miss Hussain go to a park for morning walk. One day, they reach the gate of the park at the same time and immediately start walking on the only circular track adjacent to the gate. Miss Yadav, Miss Toppo and Miss Hussain go on a clockwise direction while Miss Sharma goes anti-clockwise. Miss Hussain who is asthmatic is the slowest among the four and soon others move away from her. Like everyday she could walk only one round taking almost the same time as others to complete their morning walk. After her walk Miss Hussain reads the following instruction written at the gate while others join her one after another. “Walkers are requested to use only the 500 m walking track. Plucking of flowers and leaves are strictly prohibited. The park will remain closed from 6 pm to 5 am.”
While walking Miss Yadav overtakes Miss Hussain twice; once near the fountain and other time at the signature rock. Miss Toppo and Miss Sharma cross her three times.
Q. No. 1:
What is the total distance covered by Miss Sharma and Miss Toppo together ?
Answer: A The given walking track is 500 m and Miss Hussain takes only one round. (i) Miss Yadav overtakes Miss Hussain twice and both are running in the clockwise direction, so Miss Yadav must have walked three times on the same track. (ii) Miss Toppo crosses Miss Hussain three times and both are running in the same direction, so Miss Toppo must have walked four times on the same track. (iii) Miss Sharma crosses Miss Hussain three times, so she must have walked three times on the same track, as both are running in the opposite directions.
Total distance covered by Miss Sharma and Miss Toppo = 1500 + 2000 = 3500 m.
Q. No. 2:
How many times Miss Yadav and Miss Sharma cross each other on the track ?
Answer: D The given walking track is 500 m and Miss Hussain takes only one round. (i)
Miss Yadav overtakes Miss Hussain twice and both are running in the
clockwise direction, so Miss Yadav must have walked three times on
the same track. (ii) Miss Toppo crosses Miss Hussain three times and
both are running in the same direction, so Miss Toppo must have
walked four times on the same track. (iii) Miss Sharma crosses Miss
Hussain three times, so she must have walked three times on the same
track, as both are running in the opposite directions.
Miss Yadav and Miss Sharma both covered 1500 meter, but in opposite directions, so both will meet five times on the track.
Q. No. 3:
How many times Miss Toppo would overtake Miss Yadav ?
Answer: C The given walking track is 500 m and Miss Hussain takes only one round. (i)
Miss Yadav overtakes Miss Hussain twice and both are running in the
clockwise direction, so Miss Yadav must have walked three times on
the same track. (ii) Miss Toppo crosses Miss Hussain three times and
both are running in the same direction, so Miss Toppo must have
walked four times on the same track. (iii) Miss Sharma crosses Miss
Hussain three times, so she must have walked three times on the same
track, as both are running in the opposite directions.
Miss Toppo and Miss Yadav covered 2000 meter and 1500 meter respectively in the same direction. So, Miss Toppo will overtake twice Miss Yadav.

In a city there are three bus routes 1,2 and 3 between A and F. Route-1 has intermediate stops at B and D. Route-2 has stops at C and D. The shortest route-3 with a length of 10km stops at C only, which exactly at the middle of this route. The longest route has 3km more length than the shortest one. The distances between C and D, B and D and F and D are 4, 3 and 2 km respectively.
The
shortest route-3 = A-C-F = 10km The longest route-1 = A-B-D-F =
13km And, the route-2 = A-C-B-D = 11 km.
Q. No. 101:
In a particular code, the digits 0 to 9 are represented by a different letter of the alphabet, the letter always representing the same digit. In case the following sum holds true when it is expressed in digits, which of the following cannot be correct ? B C D E + A D E ---------- I D H G ---------
Answer: C Option A is correct because the sum of two odd or two even number is always even number. Option B is correct because if C+A is not greater than 9, then the value of B must be unchanged and if B is not same then B must be less than I. So option D is also correct.

Once I put forward an enquiry to three girls, J, R and S regarding their ages. This is what I was told. J : R is the youngest. S : There difference between R's age and mine is three years. R : Either I am 24 years old or J is 25 years old or S is 26 years old. J : All are above 24 years of age. S : I am the eldest if and only if R is not the youngest. R : S is elder to me. J : I am the eldest. R : S is not 27 years old. S : The sum of my age and J's age is two more than twice of R's age. They also conveyed to me that one of them had been lying throughout, whereas the others had spoken the truth.
Answer: B S says that she is the eldest if and only if R is not the youngest. Therefore, we have S>R>J....(i) Or reverse of the above statement i.e R is the youngest, then J is the oldest. J>S>R.......(ii) Therefore, R is younger than S in both the case.
R also says that S is elder than her. Since two people cannot be lying simultaneously, it is obviously J who is lying. As S is not 27 years of age. So, according to R, she can be 26 years of age. Because of the difference of three years between R and S. R is 23 years old and obviously from the last statement, J is of 22 years .
Answer: A S says that she is the eldest if and only if R is not the youngest. Therefore, we have
S>R>J....(i)
Or reverse of the above statement i.e R is the youngest, then J is the oldest.
J>S>R.......(ii)
Therefore, R is younger than S in both the case.
R also says that S is elder than her. Since two people cannot be lying
simultaneously, it is obviously J who is lying. As S is not 27 years of
age. So, according to R, she can be 26 years of age. Because of the
difference of three years between R and S. R is 23 years old and
obviously from the last statement, J is of 22 years .
Answer: B S says that she is the eldest if and only if R is not the youngest. Therefore, we have
S>R>J....(i)
Or reverse of the above statement i.e R is the youngest, then J is the oldest.
J>S>R.......(ii)
Therefore, R is younger than S in both the case.
R also says that S is elder than her. Since two people cannot be lying
simultaneously, it is obviously J who is lying. As S is not 27 years of
age. So, according to R, she can be 26 years of age. Because of the
difference of three years between R and S. R is 23 years old and
obviously from the last statement, J is of 22 years .
Answer: C S says that she is the eldest if and only if R is not the youngest. Therefore, we have
S>R>J....(i)
Or reverse of the above statement i.e R is the youngest, then J is the oldest.
J>S>R.......(ii)
Therefore, R is younger than S in both the case.
R also says that S is elder than her. Since two people cannot be lying
simultaneously, it is obviously J who is lying. As S is not 27 years of
age. So, according to R, she can be 26 years of age. Because of the
