Directions: Read the following information carefully and answer the question given below-
Seven people A, B, C, D, E, F and G are born in different years and like different colours - red, blue, pink, yellow, green, black and white not necessarily in the same order.
• B and E are born in consecutive years (B being younger), one of them being born in 1961.
• The one who likes black is born in 1982 and is 4 years younger than the one who likes white.
• The difference between present ages of A and D is 10 less than the difference between present ages of G and F. (A and G are older than D and F respectively.
• G was born in 1978.
• F was born in 2000 and is the youngest and doesn't like pink.
• C likes yellow and is born three years after D was born, who is 6 years older than F and 34 years younger to one who likes red colour.
• The second eldest person doesn't like green.
• The no. of people older than the one who likes pink are 1 more than the no. of people younger than one who likes blue.
When is B born?
  • a)
    1962
  • b)
    1960
  • c)
    Cannot be determined
  • d)
    None of these
  • e)
    1961
Correct answer is option 'E'. Can you explain this answer?
Verified Answer
Directions: Read the following information carefully and answer the q...
F is born in 2000
Since, F is the youngest, so, no one is born after F.
G is born in 1978
D is 6 years older than F
So,
D is born in 1994
C is born 3 years after D
C is born in 1997
So, difference in ages of G and F = 22 years
Thus, Difference in ages of A and D = 22 - 10 = 12 years
So, A is born in 1982
The one who likes black is born in 1982
White is liked by the one who is 4 years elder than who is born in 1982
So, person who likes white - born in 1978
Hence, G likes white as G is born in 1978
We get,
G - 1978 - white
A - 1982 - black
D - 1994
C - 1997 - yellow
We are left with years of birth of B and E.
CASE I:
If, B is born in 1961, then E must be born in 1960
CASE II:
And, B is born in 1962, then E must be born in 1961
Now,
D is 34 years younger to one who likes red colour
So, one who likes red colour is born in year = 1994 - 34 = 1960
Thus, case II becomes invalid
We get,
Second eldest is B who doesn't like green
F doesn't like pink
So,
The no. of people elder than the one who likes pink are 1 more than the no. of people younger than one who likes blue.
So,
Case 1:
If B is pink then, 1 person is elder than B
Then, 0 person should be younger than who likes blue, so F must like blue.
And, D must like green
Case 2:
If D likes pink, no of person elder than D = 4
No of person younger than one who likes blue = 3 which is not possible
So, this case is invalid
The final arrangement is,
B is born in 1961

Similar CAT Doubts

The chief scientist of a major vaccine producing company has the responsibility to keep the formula of the vaccine confidential. He stores the formula in his e-device with 3 consecutive locks, all of which need to be unlocked to access the formula. The first of the 3 locks is a pattern lock, the second one is a numeric lock and the third and final one is an alphanumeric lock. The pattern lock is in the form of a regular hexagon with 6 distinct vertices A1, A2, A3, A4, A5, A6, in that order. One needs to connect all the 6 vertices one after the another in any random order connecting each vertex only once and only one order of connecting the 6 vertices exists which will unlock the first lock. The numeric lock has a code of ABC, where A, B and C are single digit natural numbers. A is a multiple of 2. B is a multiple of 3, C is a multiple of 4 but not equal to A.The alphanumeric lock has a code MNPQRS, where M and N are alphabets and P, Q, R and S are digits. M and N have to be consecutive vowels or consecutive consonants, not necessarily in order. Two alphabets are said to be consecutive vowels if both of them are vowels and they are consecutive when all the 5 vowels are written in alphabetical order. For example, E and I are consecutive vowels, but A and O are not. Two alphabets are said to be consecutive consonants if both of them are consonants and they are consecutive when all the 21 consonants are written in alphabetical order. For example, D and F are consecutive consonants but D and V are not. For example, M and N can be A and E respectively or E and A respectively. P is equal to Base-Ten-Index of M. Q is equal to the Base-Ten-Index of N. R and S can only take binary values, that is, 0 or 1.Base-Ten-Index of an alphabet = Index of alphabet % 10, where Index of an alphabet is its position when all alphabets from A to Z are arranged alphabetically and a%b is the remainder when a is divided by b.For example, Base-Ten-Index of J = 10 = 0 , Base-Ten-Index of M = 13 = 3.The chief scientist can only set passwords/patterns which follow all of the conditions mentioned above.Based on the information given above, answer the questions that follow.Q.Given below is a list of patterns/passwords, some of which are in accordance with the rules mentioned and some are not. The chief scientist can use any combination of valid patterns/passwords from the following to lock the e-device. What is the total number of ways in which he can do so?Pattern:(1) A1 A2 A5 A6 A5 A2 A4 (2) A1 A2 A3 A4 A5 A6 (3) A6 A5 A4 A3 A2 A1 (4) A1 A6 A5 A2 A4Numeric password:(1) 234 (2) 434 (3) 298 (4) 634 (5) 894 (6) 230 (7) 638Alphanumeric password:(1) AE1500 (2) CD3410 (3) HJ8000 (4)QP7600 (5) AB1211 (6) YZ4600 Correct answer is '40'.
