Form the pair of linear equations in the following problems and find their solution by substitution method : Five years ago, I was thrice as old as my son and ten years later I shall be twice as old as my son. How old are we now ?

Twelve persons A, C, F, H, I, J, K, L, Q, S, T and W are sitting in two squares, such that the larger square have middle and corners seats. The smaller square has only middle seats. The persons sitting on larger square are facing towards the centre and person sitting on smaller square are facing outside the centre. The smaller square is embedded in the larger one. A, who is sitting at one of corners, is sitting second to the right of F. L and S have only one member between them. The one, who is sitting opposite to T, is second to right of J. C and K are immediate neighbors, such that one of them is sitting at one of the middle seat. I is sitting third to the left of Q, who is sitting at one of the middle seat. J is not immediate member of either of K or A. W faces K. H hsa same members between him and J as between person A and I. W is sitting second to the right of T, who is immediate left of S, who is sitting in smaller square. (Note: The person sitting on Middle seat means that the person is in between two corner seats). Four of the following five are alike in a certain way based on the given seating arrangement and thus form a group. Which one of the following does not belong to group?

Each of the questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statement are sufficient to answer the question . Read both the statements and - Five persons- A,B,C,D, and E - are sitting around a circular table. Some of them are facing towards centre while others are facing outside. Who is sitting second to the left of A ? I. B is facing outside . C is to the immediate left of B. D is second to the right of C. A is to the immediate left of E. II. D is to the immediate right of A. Both D and A are facing towards the centre. D and B are immediate neighbours of each other.
