Answers with Explanation

1.(d)  Since percentage contribution of channels and durability are same,

2.(d) Total number of points earned by all the TV’s for channels
= 15% of (683 + 650 + 640 + 625 + 620 + 600)
= 15/100 X 3818 = 572.7

3.(b) Total number of points earned by all the TV’s for child lock = 12% of 3818 = 458.16
Average points = 458.16/6
= 76.36

4.(a) Point of sound system of LG= 10% of 640
= 64
Point of flat screen of Sony  = 16% of 683
= 109. 28
= 110
Required percentage = (64/110)X100
= 59%
5.(c) Points covered by Philips for VCD/DVD
= 14/100 X 650
= 91
Points earned by BPL for Color Brightness
= 18/100 X 600
= 108
Required percentage less
=(108 – 91)/108 X 100
= 15.74%

In 2010: Total number of cars produced = 350000
P = 30% of 350000 = 105000
Q = 15% of 350000 = 52500
R = 20% of 350000 = 70000
S = 10% of 350000 = 35000
T = 15% of 350000 = 52500
U = 10% of 350000 = 35000

In 2011: Total number of cars produced = 440000
P = 40% of 440000 = 176000
Q = 20% of 440000 = 88000
R = 15% of 440000 = 66000
S = 10% of 440000 = 44000
T = 10% of 440000 = 44000
U = 5% of 440000 = 22000

6.(a) Total number of Q type cars produced in 2011 = 88000
Total number of Q type cars produced in 2010 = 52500
Required difference = (88000 – 52500) = 35500

7.(c) Total number of cars of models P, Q and T manufactured in 2010
= (105000 + 52500 + 52500)
= 210000

8.(b) If the percentage production of P type cars in 2011
= Percentage production of P type cars in 2010
= 30%
Then, number of P type cars produced in 2011
= 30% of 440000
= 132000

9.(c) Number of S type cars which remained unsold in 2010 = 15% of 35000 and number of S type cars which remained unsold in 2011 = 15% of 44000
Total number of S type cars which remained unsold
= 15% of (35000 + 44000)
= 15% of 79000
= 11850

10.(b) for model R = (70000 – 66000)/70000 X 100% = 5.71%,
