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
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
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
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
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
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%

Directions (1-6 ): Study the table carefully to answer the questions that follow:
Sale (in crores) of number of units by six Different Companies over the years.
 The year 1997 1998 1999 2000 2001 2002 Company L 107.0 80.0 28.48 38.0 26.5 36.6 M 175.1 76.0 31.38 43.0 27.5 32.8 N 156.6 66.49 43.7 45.2 19.0 40.12 O 112.4 78.24 56.6 35.1 25.1 25.0 P 95.1 111.8 53.2 48.9 22.5 37.0 Q 192.0 72.18 31.04 42.2 17.0 30.0
(Corporation  Bank PO 2006)

1. Number of units sold by Company M in the year 2002 is  what percent of the total number of units sold by all the Companies together in that year? (rounded off to two digits after decimal)
a) 14.16           b) 21.48           c) 16.28           d) 26.36           e) None of these
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
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
Explanation:
From 1997 to 98 : $\frac{80-107}{107}$ x 100% = 25% decrease approximately
From 1998 to 1999 : $\frac{28.48-80}{80}$ 28.48-80/80 x 100% = 256% decrease approximately
From 1999 to 2000 :                   38-28.48/28.48 x 100% =33% increase approximately
From 2000 to 2001 : $\frac{26.5-38}{26.5}$ x 100% =43% decrease approximately
From 2001 to 2002 : $\frac{36.6-26.5}{26.5}$ x 100% = 38% increase approximately
There is a sharp decrease in 1999 compared to other years?

4. What is the approximate average number of units sold in the year 1999?
a)407300000  b) 427400000  c ) 42740000  d) 4073000000  e) 40730000
$\frac{(28.48+ 31.38+43.7+56.6+53.2+31.05)}{5}$ = $\frac{244.4}{6}$ = 40.73 crores= = 407300000
