Based on the below information answer the following questions:
P, Q, R, S, T and U are six lectures in a college each teaching a different subject Mathematics, Physics, Sociology, Biology, Geography and History not necessarily in the same order. There are only four female lectures following information given:
i. Q teaches History
ii. No female lecturer teaches Biology or Mathematics
iii. S, who teaches Sociology, is the oldest.
iv. P is older than R and teaches physics
v. The youngest teaches Biology and U is not the youngest
vi. T teaches mathematics and is older than P but younger than Q and U
Solution
Write down the given information in the table.
Here the age is ranked in ascending order. (1 is the youngest while 6 means the oldest).
Apart from this, there is some more information that T is older than P but younger than Q and U
And P is older than R, U is not the youngest.
Given T is older than P. So, T is not the youngest, P is older than R so P is not the youngest. Also, P is younger than Q and U, So both are not the youngest. The remaining one is R and he is the youngest.
Since it is given the youngest teaches Biology R teaches biology.
Now the subjects are clear and from that, we can say the gender as well. (From point 2)
T is older than P but younger than Q and U.
From this age of Q, U>T>P
So P's rank in age is 2, T's is 3.
PQSU are Females.
