Solution 

1) % error= (6-1/6)/6 * 100 = 97%

2) 30 -40-30*40/100 = 30-52 = -22
   So 22% decrease.

3) (21- 20)/20 * 100 = 5%

4) (2100-1200)/1200 * 100 = 75%

5) (20-12)/12 * 100 = 66.66%

6) 25*40/100= 10;
   10+x/ 40+x = 75/100
  on solving x= 35

7) let B got x votes, then A got 2x, now 2x-200 = x+200
x=400
total votes= x+2x= 3x = 1200

8) S.P.= 90/100 * 85/100 * 80/100 * 75/100 * 4000 = 1836
 if he sold at 30% discount then S.P = 4000*70/100 =2800
so he will realized 2800 - 1836 = 964 more

9). No. of females = 7500*0.42 = 3150
No. of males = 7500-3150 =4350
let literate male and female are x and y respectively.
x+y= 2370
difference of illiterate male and female =90
So (4350-x)- (3150-y) = 90
on solving x-y = 1110
x= 1740
required % = 1740/4350 * 100 = 40%

10. let the time ratio will be p:q:r
so 4p:7q:11r= 24:35:77
on solving p:q:r= 6:5:7
