In a row at a bus stop, A is 7th from the left and B is 9th from the right. Both of them interchange their positions and thus A becomes 11th from the left. How many people are there in that row?

All possible representations of the letters:
Matrix - I
P ? 00, 12, 24, 31, 43
W ? 01, 13, 20, 32, 44
N ? 02, 14, 21, 33, 40
I ? 03, 10, 22, 34, 41
S ? 04, 11, 23, 30, 42
Matrix-II
A ? 55, 67, 79, 86, 98
E ? 56, 68, 75, 87, 99
R ? 57, 69, 76, 88, 95
O ? 58, 65, 77, 89, 96
H ? 59, 66, 78, 85, 97
From given matrix it is clear that all the values for word HIPS are matched in only option ( 1 ) for every letter . So , the set for the word HIPS will be 85, 41, 24, 11 .From matrix , option ( 1 ) is required answer.

A factory is a place meant for production. Similarly, a school is a place meant to impart education.

The pattern is baab. Now,
baab/baab/baab/baab ? bbaab

As per given question, we can see that letter series will be in below pattern.
C D D E
After rearranging the letters, we will get the below series.
C D D E/ C D D E/ C D D E

The unit digit remains same, and the thousand place, hundredth place and tenth place changes and follow particular pattern except in 5686.

When we are talking about the entire education system, we can 't make policy only on the basis of a particular field. hence I is not strong. II is strong because it is a fact that only professional can 't be sufficient for all the fields.

1 2 3 4 5 6
A B C D E F
D = 4, W = 4 (from backward count)
F = 6, U = 6 (From backward)
Similarly, K = 11, Q = 10

Googly is odd here, as swing, bouncer and yorker can be done during pace balling. Where as googly can be done only on spin balling.
