Solutions

S3. Ans.(c)
Sol. ∠POQ = ∠ROS = 100° (vertically opposite angle)
∠QPO = ∠OSR = 45° (Alternate Interior Angle)
∠ROS + ∠OSR + ∠x = 180°
∠x = 180 – 145
∠x = 35°

S4. Ans.(a)
Sol. ∠SCB = ∠ QRA = 142°
∠PQR + ∠QRA = 180°
∠PQR = 180° – 142°
∠PQR = 38°

S9. Ans.(a)
Sol. July : September
25   :      65
5      :   13

S10. Ans.(b)
Sol.  total no. of Kurta Manufactured by Brand B.
= 30+ 75 + 25 + 50 + 120
= 300
total no. of  Kurta Manufactured by Brand A.
= 60 + 30 + 100 + 55 + 65
= 310
Diff. between Brand B and Brand A
= 310 – 300
= 10
