Answer:

1.a
total no. of car produced in 2009 - 100000 + 100000 ×
a.= 108000 cars.
no. of the Alto produced in 2009 - 27000 cars.
total no. of car produced in 2010 - 108000 + 100000 × .09 =117720
no of Alto produced in 2010 = 32961.6
% increase = [(32961.6-27000)/27000]*100 = 22.08% approx 22%

2.d;
Maruti Ritz produced in the year 2009 = 108000 × 22/100 = 23760
required % =  23760/100000= 23.76% approx. 24%

3.d;
car produced in 2011 is - 134400
car produced in 2010 -  134400/1.12 = 12,0000
Maruti esteem produced in the year 2010 -120000*12/100   = 14400 car

24.e; 
Ratio will be = (will be direct ratio of %)
= 2:3

5.e;
production of car in 2009 - 140000
in 2010 - 140000 + 1400000 ×.09= 152600
2011 - 152600 × 1.12 = 170912
Avg.=(140000+152600+170912)/3=154504
   
6.a; 
LG users = 57.6° = 16%
Total users = (80*16)/100  = 12.8 lakhs

7.d;
Spice users = 43.2° = 12%
HTC users = 28.8° = 8%
Difference = 12 – 8 = 4%
4% of 80 lakhs = 3.2 lakhs

8.b;
Nokia users = 108° = 30%
Samsung users = 86.4° = 24%
Ratio =30/24   = 5 : 4

9.d;
Motorola users = 36° = 10%
HTC users = 28.8° = 8%
 % =  10/8*100 = 125%

10.d;
Nokia users = 108° = 30%
LG users = 57.6° = 16%

% more = (30-16)/16*100  = 175/2=87.5%
