Q3. 70.4/2= 35.2

add to respective categories: Car/van pool: 14.3+35.2=49.5 (is th correct answer been shown??)

or, 1.11x=433

=>x=390.09

______________________________________________

Q5. y=mx+c

0=-3x+6

=> x=2

______________________________________________

Q6. side of inner= sqrt(t^2+s^2)

Area= sqrt(t^2+s^2)*sqrt(t^2+s^2)= t^2+s^2

Hence, Equal

Q7. __ __ __ __

1st position: 1,3,5,7,9 (5 ways)

4th position: 0,2,4,6,8 (5 ways)

Q3. 70.4/2= 35.2

add to respective categories: Car/van pool: 14.3+35.2=49.5 (is th correct answer been shown??)

correction: 1/2 of 1/2 join pool Car/van

hence, 70.4/2= 35.2/2= 17.6

add to respective category: Car/van pool: 14.3+17.6= 31.9

rest r fine.
