Answer:-

1.Sol:- (1)


13/4

2. Sol: - (2)

 =
 = 6 x (36 – 15) = 126

3.Sol:- (4)

2x + 3 + x – 8 + x + 13 = 0
= x = -2
 =

4. Sol:-

Length of cuboid = 30 cm
Breadth and height of cuboid = 5cm
Total surface area = 2 ( 150 + 25 + 150)
= 650
Total surface area of cube =  6 x 25 = 150
3 cubes =  3 x 150 =  450
Required ratio = 650 : 450
= 13 : 9

5.Sol:- (3)

Total work =
33%Work done by A and B =  =  12 days


6.Sol:-  (1)


5924 = 28
 = 208

7.Sol:- (4)

Sum of 18 numbers = 18 x  52 = 936
Sum of first  8 number = 496
Sum next seven number = 315
Sum of remaining number = 936 – 496 – 315 = 125
ATQ,
= x + x + 6 + x + 5 = 125
3x =125 – 11
X =  38
Required average = 38 + 2.5 = 40.5

8 Sol. (3)

Ratio of share = 3 : 2
A's share

9. Sol. (A)

PA×PB  =  PC× PD
(6+4)×4 = (3+PD)×PD
PD=5

10. Sol. (C)

=13+13+1.69
=27.69%
