The second highest number is 782. Hence the required middle digit is ‘8’.
2-2; Since half of the remaining play both football and cricket, the remaining 10 who
play only cricket comprise the other half. Now, both the halves must be equal.
Hence, required no. of students = 10.

(6-10): We have information that F’s flat is second to the right of J’s flat, which is
exactly opposite of C’s flat facing North. Thus, we get

Again, since I and E have flats at the two ends of the same row. This implies
that the flats of both I and E can be in the same row in which the flats of B, C

Now, we have been given that the flats of E and H are opposite each other.
Thus reject case I, because in that case E and F are opposite each other. Hence,
the positions of the ten flats are as follows.

11-1; We have to look for consonant-number-vowel sequence. But in the given
arrangement there is no such sequence.

(17 − 8) = 9th element from the left end, i.e, ‘M’.

Hence conclusion III does not follow. Again statement (b) + statement (c) gives
no conclusion. Hence, conclusion I and II do not follow.
17-4; Statement (a) + conversion of statement (b) gives no conclusion [ ... A + I =
no conclusion]. Hence conclusion I and conclusion III do not follow. But these
two conclusions make a complementary pair. Hence either conclusion I or
conclusion III follows. Again from statement (b) and statement (c), we get
"All pens are papers" [ ... A + A = A] And conversion of "All pens are papers "
gives conclusion II. Hence conclusion II follows.

19-5; Statement (b), statement (c) gives conclusion "Some hammers are rings"

20-5; Statement (a) + statement (b) gives conclusion "All hotels are belts".

conclusion II. Hence conclusion II follows. Again conclusion III follows from
conversion of statement (c). Hence conclusion III follow.
