Pattern 2:
1. There are two water tanks A and B, A is much smaller than B. While water fills at the rate
of 1 liter every hour in A, it gets filled up like, 10, 20, 40, 80, 160 in tank B. (At the end of
first hour, B has 10 liters, second hour it has 20 liters and so on). If tank B is 1/32 filled of the
21 hours, what is total duration of hours required to fill it completely?
a) 26 B)25 c)5 d)27
Solution: for every hour water in tank in B is doubled,
Let the duration to fill the tank B is x hours.
x/32 part of water in tank of B is filled in 21 hours,
Next hour it is doubled so,
2*(x/32) part i.e (x/16) part is filled in 22 hours,
Similarly (x/8)th part in 23 hours,(x/4)th part is filled in 24 hours,
(x/2)th part is filled in 25 hours, (x)th part is filled in 26 hours
So answer is 26 hours.

Pattern 3:
1. 6 persons standing in queue with different age group, after two years their average age will
be 43 and seventh person joined with them. Hence the current average age has become 45.
Find the age of seventh person?
a) 43 b) 69 c) 52 d) 31
Solution:
Total age of 6 persons is x hours,after two years total age of 6 persons is x+12
Average age of 6 persons is after two years is 43
So (x+12)/6=43,then solve x,
After 7th person is added then (x+7th person age)/7=45
So we will get 7th person age easily

1. In the reading room of a library, there are 23 reading spots. Each reading spot consists of a
round table with 9 chairs placed around it. There are some r eaders such that in each occupied
reading spot there are different numbers of readers. If in all ther e are 36 readers, how many
reading spots do not have even a single reader?
a) 8 b) none c) 16 d) 15
Solution: 23 reading spots, Each reading spot consists of 9 chairs placed around it so There
are some readers such that in each occupied reading spot ther e are diff erent numbers of
readers.
For each table different no of persons are sat,so for first table 1 person is sit,2nd table 2
persons are sit 36
readers means(1+2+3+4+5+6+7+8 so 8 tables are filled so 23-8=15 r eading spots does not
have single reader.
