10.The ratio between the length and the breadth of a rectangular park is 3 : 2. If a man cycling along the boundary of the park at the speed of 12 km/hr completes one round in 8 minutes, then the area of the park (in sq. m) is:

(a) 15360

(b) 30720

(c) 153600

(d) 307200

Answers and Solution:

1.(a)27 is divided by 13
so Required remainder = remainder by 27/13 = 1

2.(c)sum of digital at odd places of 854A9A = A+A+5 =2A+5
Sum of digits at even places of 854A9A =8+4+9 = 21
(2A+5)-21 = 0 OR 11 or 22
so 2A+5-21 = 0
2A =16
A  = 8

3.(a) Soln= 5 hectares and 76 ares = 57600 m^2, find perimeter then multiply it by 6.
So length of wire is 5760m.

4.(c) Speed of train = 162km/hr= 162 x 5/18 = 45 m/sec
If the length of the platform be x meters, then
(380+x)/16= 45
x+380=720
x=(720-380)=340
then 340/17 = 20 m/s
5.(d)
6.(d) Soln-let three angles of the quadrilateral be 11x0, 9x0 and 7x0 respectively.
Now according to the question, 11x+9x+7x=360-36=324
27x=324
x=    =12
 required difference = 11x-36= 960

7.(c) Soln – Total amount for two years = 1000(1.5)2 =2250
Now, interest for third year = (2250×50×1)/100 = 1125
8.(a)
9.(a)
10.(c)Perimeter = Distance covered in 8 min
= (12000/60 x 8)m = 1600 m.
Let length = 3x metres and breadth = 2x metres.
Then, 2(3x + 2x) = 1600 or  x = 160.
Length = 480 m and  Breadth = 320 m.
Area = (480 x 320) meter square = 153600 meter square
