2) 75 km/hr
3) 40 km/hr
4) Cannot be determined
5) None of these
Answers With explanations:
1. 2;18 :  360°
1 :  20°
Smallest angle of quardilateral = 2 × 20 = 40°
Smallest angle of triangle = 40°
Remaining two angles of triangles are
40 × 2 = 80° and 180 - (80 + 40)= 180 - 120 = 60°
2. 5;Total number of notebooks sold in two weeks = 2 × 7 × 10 = 140.
Total commission earned on selling of notebooks = 140 × 457 ×

Rs 2559.2
= Rs 1344
Total commission earned = 2559.2 + 1344 = Rs 3903.2  3900
3. 1;Speed of train A =
240
 12 m / s
20
In 50 seconds, the train covers 50 × 12 = 600 m
Length of train B = 600 - 240 = 360 metres.

Minimum passing marks for girls = 35% of 1500 = 35×15 = 525

6. 1;The work takes 20 days when 8 men work.
In 1 day, 20 × 8 = 160 men are required to finish the work.
Similarly,
In 1 day 32 × 8 = 256 women are required to finish the work
So, 20 × 8m = 32 × 8w

7. 5;Side of the square
 1,024 cm2  32cm
Length of rectangle = 32 × 2 cm
Breadth of rectangle = 32 - 12 = 20 cm
Required ratio = 64 : 20 = 16 : 5
8. 5;Let the first number be x.
x + x + 2 + x + 4 + x + 6 + x + 8 = 220
 5x = 220 - 20 = 200  x = 40
Second lowest number of set B = 40 × 2 - 37 = 43
Required sum = 42 + 43 + 44 + 45 + 46 = 220
