1
In which of the following months is the average of the number of opened accounts the maximum?
» Explain it
A
The average number of accounts in Nov

=   80 + 50 + 72 + 75  =  277  = 69.25
4 4

The average number of accounts in Oct
 
=   62 + 55 + 48 + 65  =  230  = 57.5
4 4

The average number of accounts in Aug
 
=   65 + 30 + 35 + 50  =  180  = 45
4 4

The average number of accounts in July
 
=   35 + 32 + 50 + 45  =  162  = 40.5
4 4

The average number of accounts in Sep
 
=   55 + 45 + 40 + 60  =  200  = 50
4 4

Therefore, in Nov the average number of accounts opened is the maximum.
 
Hence, option A is correct.

2
The number of accounts opened in Sept is approximately what per cent more or less than the number of accounts opened in May? 
» Explain it
E

The total number of accounts opened in Sept

=   55 + 45 + 40 + 60

=   200


The total number of accounts opened in May

=   25 + 22 + 30 + 35

=   112


   Reqd%

=    200 – 112  × 100
112

=    88  × 100
112

=   78.57 ≈ 79%


Hence, option E is correct.

3
What is the ratio of the number of accounts opened in SBI to that opened in BOB from May to Dec?
» Explain it
D
Number of accounts opened in SBI from May to Dec

=   25 + 28 + 35 + 65 + 55 + 62 + 80 + 90
 
=   440


Number of accounts opened in BOB from May to Dec

=   22 + 18 + 32 + 30 + 45 + 55 + 50 + 60

=   312


Reqd ratio =  440  = 55 : 39
312


Hence, option D is correct.

4
In which bank is the average number of accounts opened the maximum?
» Explain it
E

Total number of accounts opened in SBI

=   25 + 28 + 35 + 65 + 55 + 62 + 80 + 90

=   440


∴   Avg no. accounts in SBI

=    440  = 55
8


The average number of accounts opened in BOB

=   22 + 18 + 32 + 30 + 45 + 55 + 50 + 60

=   312


∴   Avg no. accounts in BOB 

=    312  = 39
8


The average number of accounts opened in Canara

=   30 + 45 + 50 + 35 + 40 + 48 + 72 + 85

=   405


∴   Avg no. accounts in Canara

=    405  = 50.625
8


The average number of accounts opened in PNB

=   35 + 42 + 45 + 50 + 60 + 65 + 75 + 78

=   450


∴   Avg no. accounts in PNB

=    450  = 56.25
8


Therefore, in PNB the average number of accounts opened is the maximum.
 

Hence, option E is correct.

5
The average number of accounts opened in Canara is what per cent more or less than the average number of accounts opened in BOB? (approximation)
» Explain it
E

The average number of accounts opened in Canara

=   30 + 45 + 50 + 35 + 40 + 48 + 72 + 85

=   405


∴   Avg no. accounts in Canara

=    405  = 50.625
8


The average number of accounts opened in BOB

=   22 + 18 + 32 + 30 + 45 + 55 + 50 + 60

=   312


∴   Avg no. accounts in BOB 

=    312  = 39
8


Reqd% 

=    50.625 – 39  × 100 =  11.625  × 100
50.625 50.625

= 22.96 ≈ 23%


Hence, option E is correct.
