Answer: (a)

• The person whose age is 52 is taking class three days after P.

• The person who is taking class immediately before M is taking class either two days before or two days after P.

• Neither P nor the person whose age is 52 is taking a class on Thursday.

• The number of persons takes class after M is the same as the number of persons takes class before Q.

• The difference between the ages of M and Q is 6.

• The age of L is two less than half the age of Q.

Here, in case 1 and case 2, Q's age is either 46 or 58. If Q's age is 46, then L's age is 21 which is not possible as ages should be between 22 and 66.

Thus, Q's age is 58 and L's age is 27.

In case 2a, Q's age is 52 and L's age is 24.

• Only one person is taking a class between the person who is taking class immediately before K and the person who is taking class immediately before Q. This eliminates case 1.

• N's age is 23. The number of persons between K and N is the same as between P and Q.

• N is taking a class after O, whose age is twice the age of N. In case 2 and case 2a, N's age is 23 and O's age is 46. Now in case 2a, M's age is either 46 or 58, but 46 is not possible thus M's age is 58.

• P's age is equal to the reverse of the digits of the age of L, who takes class either first or last.

In case 2, the reverse of the digits of L's age is 72, which is not possible. Thus case 2 eliminates.

In case 2a, the reverse of the digits of L's age is 42. Thus P's age is 42.

One of them is 63 years old.
