x = -2 or x = (\frac{1}{4})

(x + 2)(4x - 1) = 0

y = 2 - 7x - 4x²

TXY = XTY = 47^o(Basa angle of an isosceles (\bigtriangleup))

< TYZ = 94^o

n^o = 180 - (94^o + 34^o)

= 180^o - 128^o

= 52^o

(\begin{array}{c|c} Mark & No. of Candidate\hline 60 & 40\ 70 & 25\ 80 & 15\ 90 & 10 \100 & 5 \hline & 95 \end{array})

Angle of apple = 360 - 315 = 45^o

No. of apple = (\frac{45}{360} \times 400)

= 50
