6. of 2 : 4 : 4, respectively. If a student obtained 50% in the first paper, 60% in the second, and 65% in the third,
2*50/100+4*60/100+4*65/100=6
X=6/10*100=60%


7. A
467+133=30%X
x=2000
2000*35/100=700


8.B
 total valid vote 90%-60
winner=50%,looser=(90%-60-50%)=40%-60
so 50%-(40%-60)=420
10%=360
total vote 100%=3600



9. D.
total no of audi car=29400
Audi+ non audi= 29400
Audi car=16000
Non audi car =29400-16000
13400
Now 55% of 29400= red audi car+non red audi
29400*55/100=16170
Non red audi car=16170-98*16000/100=15680
16170-15680=490
490*100/16170=3.33%


10. The price of petrol is increased by 25%.
25*100/125=20%
