Answer

1. Option A
Solution:
Area of a trapezium = 1/2 (sum of parallel
sides) * (perpendicular distance between
them) = 1/2 (22 + 16) * (11) = 209 cm2

2. Option E
Solution:
Let the sides of the rectangle be l and b
respectively.
From the given data,
√(l2 + b2) = (1 + 1 1/12) lb
=> l2 + b2 = (1 + 13/12) lb = 25/12 * lb
12(l2 + b2 ) = 25 lb
Adding 24 lb on both sides
12 l2 + 12b2 + 24lb = 25 lb
12(l2 + b2 + 2lb) = 49 lb
12(l + b)2 = 49lb
but 2(l + b) = 42 => l + b = 21
So 12(21)2 = 49lb
Solve, we get lb = 108
Since l + b = 21, longer side = 12 m

3. Option B
Solution:
Let the length and the breadth of the floor
be l m and b m respectively.
l = b + 80% of b = l + 0.8 b = 1.8b
Area of the floor = 5760/2 = 2880 sq m
l*b = 2880 i.e., l * l/1.8 = 2880
l = 72

4. Option C
Solution:
Area of the path = Area of the outer circle –
Area of the inner circle = π{7/2 + 7}2 – π
[7/2]2
= 308 sq m

5. Option B
Solution:
Let the side of the square be a cm.
Parameter of the rectangle = 2(62 + 50) =
224 cm Parameter of the square = 56 cm
i.e. 4a = 56
So a = 14
Diameter, d of the semicircle = 14 cm
Circumference of the semicircle = 1/2(π)(r)
+ d
= 1/2(22/7)(7) + 14 = 25 cm

6. Option E
Solution:
2πrh = 1408, h = 16
Solve both, so r = 14
Volume = π r2h = (22/7) * 14 * 14 * 16 =
9856

7. Option C
Solution:
Radius of cone = 30/2 = 15, radius of ball =
10/2 = 5
Volumes will be equal, so
(1/3) π r2h = (4/3) π R3
152h = 4* 53
So h = 2.2

8. Option B
Solution:
Distance covered in one round = 2 x π x r =
6 m
Distance covered in 1 second = 3 x 6 = 18
m
So distance covered in 9 seconds = 18×9=
162m

9. Volume of the container = Volume of the
cylinder + Volume of the hemisphere
Volume of the container = π 62h + (2/3) π
63 = 576π
= π 36 (h + 4) = 576π
Solving we get h = 12
So the height of the container = 12 + 6 = 18
m

10. Option D
Solution:
r1/r2 = 3/2 or r1 = 3/2 * r2
CSA1/CSA2 = 2πr1h1/2πr2h2 = 3/5
So h1/h2 = 2/5
Volume1/ Volume2 = πr12h1/ πr22h2 =
9/10
