1. What is the total number of items accepted by Company B for the years 2001, 2002 and 2003 together? (PNB SO 2009)
a) 57,34,000 b) 57, 37,000 c) 57,33,000 d) 57,27,000 e) None of these
Answer : B
Explanation :
Total number of
items accepted by company B :
In the year 2001 => 18 x
$\frac{94}{100}$
= 16.92 lakh
In the year 2002 => 20 x$\frac{93}{100}$
= 18.6 lakh
In the year 2003 => 23 x $\frac{95}{100}$ = 21.85 lakh
Therefore, the total number of items accepted
by Company B for the years 2001 ,2002 and 2003 => (16.92 + 18.60 + 21.85) lakh = 5737000
2. What is the total number of items rejected by Company D over all
the years together?
a) 21,20,000 b) 20,19,000 c) 21,19,000 d) 20,21,000 e) None of these
Answer : D
Explanation :
Total number of items rejected by the
company D all years together :
Year 2001 : 33 x $\frac{10}{100}$ = 3.3
Year 2002 : 37 x $\frac{9}{100}$ = 3.33
Year 2003 : 35 x $\frac{8}{100}$ 2.8
Year 2004 : 36 x $\frac{9}{100}$ = 3.24
Year 2005 : 34 x $\frac{11}{100}$ = 3.74
Year 2006 : 38 x $\frac{10}{100}$= 3.8
Total number of items rejected by company D over the years
= (3.3 + 3.33 + 2.80 + 3.24 + 3.74 + 3.8) lakh = 2021000
3. Approximately, what is the overall percentage of items accepted by
all the companies together in 2004?
a) 94 b) 88 c) 95 d) 89 e)
92
Answer: E
Explanation: Overall percentage of items accepted by all the companies together in
2004 :
$\frac{(89+92+95+91+94}{5}$=$\frac{461}{5}$ = 92.2% = 92
4. What is the ratio between
the number of items rejected by Company C for 2001, 2002 and 2003 together and
the number of items rejected by Company A for these three years together
respectively?
a)316 : 377 b) 363 : 377 c) 363 : 754 d) 332 : 377 e) None of
these
Answer : E
Explanation :
Number of items rejected by company C
In the year 2001 :
27 x $\frac{7}{100}$ = 1.96
In the year 2002 : 30 x $\frac{6}{100}$= 1.8
In the year 2003 : 32 x $\frac{8}{100}$ = 2.56
Number of items rejected by company C
from 2001 to 2003 = (1.9+ 1.8 + 2.56) lakh = 6.32 lakh
Number of items rejected by company A :
In 2001 : 27 x $\frac{12}{100}$= 3.24
In 2002 : 32 x $\frac{8}{100}$ = 2.56
In 2003 = 29 x $\frac{6}{100}$ = 1.74
Number of items rejected by company A from 2001 to 2003 =(3.24 +
2.56 + 1.74) lakh= 7.54 lakh
∴ Required ratio = 6.32 : 7.54 = 316 : 377
5. What is the overall
percentage of items rejected by Company E over all the years together?
a) 9.2 b) 8.2 c) 8.5 d)
8.8 e) None of these
Answer: C
Explanation :
The overall percentage of items rejected by company E over all the
years together = $\frac{(11+10+9+6+7+8)}{5}$ = $\frac{51}{6}$ = 8.5%

digits after decimal)
a)
14.16 b) 21.48 c) 16.28 d) 26.36 e)
None of these
Answer : c
Explanation:
Number of units sold by company M in the year 2002
=32.8 crores
Number of units sold by
all six companies in 2002
=
(36.6 + 32.8 + 40.12 + 25 + 37 + 30) crores
=
201.52 crores
∴ Required
percentage = $\frac{32.8}{201.52}$ x 100 %=16.275%
= 16.28%
2. Which Company has sold the maximum number of units
over the years?
a)
Q b) M c) N d) P e) None of these
Answer : B
Explanation :
Number
of units sold (over the years) by the each company as follows:
L
= (107 + 80 + 28.48 + 38 + 26.5 + 36.6) = 316.58 crores
M
= (175.1 + 76 + 31.38 + 43 + 27.5 + 32.8) = 385.58 crores
N
= (156.6 + 66.49 + 43.7 + 45.2 + 19 + 40.12) = 371.11 crores
O
= (112.4 + 78.24 + 56.6 + 35.1 + 25.1 + 25) = 332.44 crores
P
= (95.1 + 111.8 + 53.2 + 48.9 + 22.5 + 37) = 368.5 crores
Q
= (192 + 72.18 + 13.04 + 42.2 + 17.0 + 30) = 384.42 crores
3. Which year is the percentage increase/decrease in
the number of units sold from the previous year the lowest for Company L?
a)
2000 b) 2002 c) 2001 d) 1998 e) None of these
Answer : E
Explanation:
From
1997 to 98 : $\frac{80107}{107}$
x 100% = 25% decrease approximately
From
1998 to 1999 : $\frac{28.4880}{80}$
28.4880/80 x 100% = 256% decrease approximately
From 1999 to 2000 : 3828.48/28.48 x 100% =33% increase approximately
From 2000 to 2001 : $\frac{26.538}{26.5}$
x 100%
=43% decrease approximately
From 2001 to 2002 : $\frac{36.626.5}{26.5}$ x 100%
= 38% increase approximately
There
is a sharp decrease in 1999 compared to other years?
