Answer Key-

Q-(1) Sol-(3)

 

(I) x² + 11x + 30 = 0

x²+ 6x + 5x + 30 = 0

x(x+6) +5(x+6) = 0

(x + 6) (x + 5) = 0

x = -6,-5 

(II) y² + 7y +12 = 0

y² + 4x + 3y + 12 = 0

y(y+4) +3(y+4) = 0

(y + 4) (y + 3) = 0

y = -4,-3

y > x

Q-(2) Sol-(5)

x = 5, y =

Relation can't be established

Q-(3) Sol-(3) 

(I) 2x² + x -1 = 0

2x² + 2x -x-1= 0

2x(x+1) -1(x+1) = 0

(x + 1) (2x-1) = 0

x = -1, 1/2

(II) 12y² -17y +6 = 0

12y² - 9y -8y + 6 = 0

3y(4y-3) -2 (4y-3) = 0

(4y - 3) (3y - 2) = 0

y = 3/4,2/3

y > x

Q-(4) Sol-(5)

(I) x =  

x = 161

(II) y = +161

hence , x= y

Q-(5) Sol-(3)

On solving] x = -2, y=8/3

y > x

Q-(6) Sol-(2) 

Total ways = 

Q-(7) Sol-(5)

Number of bags = 

Q-(8) Sol-(3)

Q-(9) Sol-(4)

 

Q-(10) Sol-(4)
