15. 2
Hints:
1. valid votes got by other person = 8400 *36/100 =3024
2. let Speed of man = x and speed of stream = y
48/(x+y) + 48/(x-y) = 14
4/(x+y) = 3/(x-y)
on solving, y = 1km/hr
3.let Speed of Boat = x and speed of stream = y
So distance is same,
so 2/(x+y)= 1/(x-y)
on solving x= 3y
x:y = 3:1
4. let total person was x
x*45= (x+500)*40
on solcing x= 4000
5. 22.5
6. 217
7. 13
8. probability either both at green or either both are yellow = (4c2+3c2)/(15c2) = 9/105 =3/35
9. 1- 9c5/15c5 =137/143
10. 6c2/15c2 = 1/7
11. 2c2*4c2/15c4 =2/445
12. 12c3/15c3 = 44/91
