(b) 288.4            
(c) 308.4                                              
(d) 296.8 

Answers with Explanation:-

1. (a):
Length of the rectangle = 112/8 = 14 cm, so  perimeter= 44 cm,
Circumference= 132-44=88 cm,
R = (88 × 7 )/(2 ×22)  = 14cm
So area = 616cm

2. (d):

3. (b):
Number = 740 × 35/100 - 34 = 225
2/5  of the number=90

4. (c):
The largest angle of the quadrilateral (6 ×360)/(6+4+3+5) = 120 degrees
Smallest angle of the triangle = 120 × 1/4 = 30 degrees
If second largest angle of the triangle = (x + 10)
So 30+ x+ x+10 = 180 , x = 70 degrees

5. (b):
6. (a)
Let the total amount be x.
C’s original share = 3x / 6 = x / 2
C’s new share = 2x / 9
Now
(x / 2) – (2x / 9) = 60
x = 216

7. (d)
prashant marks in A = 83
prashant marks in B = 75% of 120 = 90
Now
(83 + 90 + x) / 360 * 100 = 80
x = 115

8. (c)
No. of erasers > No of pencils > No of pens
Possible combinations
Erasers = 11, Pencils = 8, Pens = 7 
OR
Erasers = 10, Pencils = 9, Pens = 7

9. (c)
Let the shares of A and B be 5x and 6x. Now
5x + 6x = 31394
x = 2854
Required difference = (3 * 5)x – (2 * 6)x = 3x = 8562  

10. (b)
Let the numbers be x, x + 1 and x + 2. Now
x + (x + 1) + (x + 2) = 2475
x = 824
Required number = 35% of 824 = 288.4
