36. (C) Best estimate for 6143 590 is 6000 600
= 3600000.

37. (C) 12 + 20  4 ? 8 – 2 = 50

 12 + 5 ? 8 – 2 = 50

 5 ? 8 = 40

 5  8 = 40

40. (B) Area of shaded region = 18 cm2.

The given figure can be redrawn as
shown.



 The total area of shaded region is equal
to the area of two squares

 Area of two squares = 18 cm2

 Area of a square = (18  2)cm2 = 9 cm2

 The side of a square = 29 cm

= 3 cm.

41. (C) 3y + 2y = 180o
