Explanation to Paper II

1. S.I = 60,000 * 10 /100
= Rs. 6000
Rent received = 1500 * 12
= 18000
Therefore debt cleared in one year = 18000 - 6000
=12000
Therefore in 5 years.

2.  800 - 600 = 200
n = 6 months. = 1 /2 year
r = 100 I /Pn
= 100 * 15.50/ 200 * 1/2
= 1550 / 100
= 15.5%

3. A = P ( 1 + r/ 1002 ( 1 + r /100)
= 2400 ( 1+ 5 /1002 ( 1 + 2 1/2/100)
= Rs. 2712.15
Therefore C. I. = 2712.15 -150; 2400
= Rs. 312.15

4. Perimeter of square = 4a = 4 * 45
=180 m
Length of fence = 10 * 180
=1800m. with 10 lines of wire.
Therefore cost of wire = 1.50 * 1800
= Rs. 2700

5. External volume = l * b * h
= 10 * 6 * 4
= 240 cm3
Internal dimensions = ( 10 -2); ( 6- 2); ( 4- 2)
= 8 , 4 , 2 cm.
Internal volume = 8 * 4 * 2
= 64 cm3
Therefore volume of cube = 240 - 64
= 176 cm3

6.  Let radii --> 2x and 3x
Let height --> 5y and 3y
V1 /V 2= ( 22 /7 ) ( 2x ) 2 ( 5 y ) / ( 22 /7 ) ( 3x ) 2 ( 3y )
= 20 / 27

7. Diameter of a roller = 60 cm
r = 30 cm = 0.30 m
Height of roller = 1.00 m
Curved surface area = 2 ( 22 / 7 ) rh
= 2 * ( 22 / 7 ) * 0.30 * 1
= 1.32 / 7
= 0.88
Area covered by roller = 500 * 0.88
= 88 * 5
= 440 cm2
Therefore cost of levelling = 0.50 * 440
=5 * 44
= 220

8.  Since a+b+c = 0
a+b = -c
(a+b2=(-c2)
a2+2ab+b2=c2
a2+b2-c2= -2ab
(a2+b2+c2) 2=(-2ab) 2
or
a4+b4+c4+2a2b2-2b2c2-2c
2a2=4a2b2
or
a4+b4+c4=2a2b2+2b2c2+2c2a2
or
=2(a2b2+b2c2+c2a2)
a4+b4+c4/a2b2+b2c2+c2a2
= 2

9.  Let x be the total value of the property.
x = x/2+x/4+1/5x+10000
= (10+5+4)x/20+10000
= 19x/20+10000
= 20*10000
= 200000

10.  m/n = 2/3
3m = 2n
now, 3m+5n/6m-n = 2n+5n/4n-n = 7n/3n = 7/3

11.  a+b = 27
5a+11b = 195
solving simultaneously we have,
a = 17 b = 10

12.  40% of 5/6 = 40/100*5/6 = 1/3

13.  3 leaps of the dog = 4 leaps of the hare.
1 leap of the dog = 4/3 leaps of the hare.
4 leaps of the dog = 16/3 leaps of the hare.
Speed of the dog : Speed of the hare
16: 15

14.  9 days earlier mean that the work should be completed in (42-9) = 33 days.
No. of Men = 42*55/33 = 70
Hence the no. of extra men = 70-55
=15 men

15.  Total cost of the electronic buzzer = Rs.215+Rs.25 = Rs.240
Selling Price = Rs.300
Profit% = 60/240*100 = 25%

16. 7500*20%=1500
45% of 6000=2700
Hence[1]

17. At the speed of 60 kmph, aunt will reach nashik in 4 hours.
The distance between mumbai and nashik is 240 kms.
If 120 km are to be covered in 3 hours then aunt should travel at the uniform speed of
120/3 = 40kmph

18. If x and y are the ages of Nitya and Nitya's aunt,
x+y = 63
y-x = 4(x-4)
we have Nitya's age = 15 years
her aunt's age = 48 years

19.  First watch ticks after 95/90 seconds.
second watch after 323/315 seconds.
LCM = 19*5*17/45 seconds.
No. of times they will tick in first 3600 seconds = 3600/(19*5*17)/45
Once they have ticked together in the begining , 50 in 1 hour they tick 100+1 = 101 times

20. If area = S, Sides = sqrt(S)
If side is doubled i.e. 2sqrt(S)
area = {2sqrt(S)}2
= 4S

21. Let a and b be the numbers where b is the bigger number.
b =3/2a
a-b = 2400(given)
3/2a2= 2400
a2= 1600
a = 40

22. 6 M = 8W, 2W = 3B, 4B = 5G
1 G = Rs. 50 a day.
Now, 1B = 5/4G 1 W = 3/2 * 5/4G
1 M= 8/6* 3/2* 5/4G = 5/2G
1 M = 5/2 * 50 = 125/-Rs.

23. The distance covered by the train in 30 seconds = 6000/3600* 30 metres
= 500 metres.
Length of the Bridge = 500 - 150
= 350m.

24. If we assume that the sum = Rs. 100
Then, 1st rate of interest = 100*100/100*5 = 20
2nd rate of interest = 200*100/100*12 = 16 2/3
76n1=5, x1= 42.2 n2 = 4, x2 = 35.5
x12 = n1x1+ n2x2 / n1+n2
= 5 * 42.2 + 4 * 35.5 /9
= 211.0 + 142.0 /9
= 353 /9
= 39 2/9

25.*6, /3
Hence[1]

26. Area of the four walls.
= 2(length + breadth ) * height
= 2 (30 + 20 ) *12 sq. meteres
= 1200 sq. metres
Total cost of painting = Rs. 1200*25/100
= Rs.300

27.Product of 3 sqrt (4), 6 sqrt (6), 2 sqrt (5) is
4 1/3 * 6 1/6 *5 1/2
=42/6 * 61/6 * 53/6=(42 * 6 * 53)1/6
=( 16 *6 *125)1/6
= 6 sqrt.12000

28. A takes 6 hours to complete a work.
He can complete 1/6th of the work in one hour.(taking complete work as 1.)
B takes 8 hours to complete it.
He can complete 1/8th of the work in one hour.
Together, A and B can complete,
1/6+1/8 = 14/48 = 7/24 of the work.
Hour     Work
1           7/24

?            24/24

Hence, [1]

29. In one hour, C can complete 1/12th of the work.
In two hours, he can complete 1/12*2 = 2/12th of the work.
A and B start work simultaneously,
together work completed by A and B,
1/6+1/8 = 14/48 work = 7/24 work.
In 2 hours they complete 7/24*2 = 7/12 work
Total work done by A,B,C = 7/12+2/12 = 9/12
Total work to be completed = 12/12 or 1
Remaining work = 3/12
Hour       work done by A
1                           1/6

?                           3/12

3/12*6 = 1.5 hours
Hence[2]

30./4, *7
Hence[1]

31. In 1 hour C can empty 1/8th of tank
In 1 hour amount of water filled in the tank = A+B-C
= 1/6+1/10-1/8
68/480 = 17/120
Hour                Water filled in tank
1                                    17/120
?                                  120/120

= 120/17 = 7.05 hours

32. Let the present ages of Ram and Shyam be R and S resp.
3R-2S = 10 -- I
4S-5R = 10 -- II
15R-10S = 50
-15R+12S = 30
2S = 80
S = 40
R = 30
Hence,[1]

33. Let their present ages be A and B.
3A-B = 100 -- I
2A-B = 50 -- II
3A-B = 100
-2A-B = 50
A = 50
B = 50
Sum of their ages = A+B
=100
Hence[2]

34. Let their present ages be X and Y.
X+Y = 105 --I
1.5X-2Y = 0 --II
X = 60
Y = 45
Hence[4]

35.               M      D     H     L
old               10      20     5     20
new               x       5     10     100
10/x = 5/20*10/5*20/100
x = 100

36. a4+b4 = (a2+ab+b2)(a2-ab+b2)
=(a2+4a+8)(a2-4a+8)
=(a2+8)2-(4a)2
=a2+64
Hence[3]

37. x = 10*2 = 20 days
100 men would require 20 days from 46 days
46+20 = 66 days
But we want to complete the work in 56 days.
Hence[1]

38. Exam 1 = 30/50*100 = 60%
Exam 2 = 40/50*100 = 80%
Increase in percent =20%
percent in increase = 20/60*100 = 33 1/3%

39. a)30/100*60/100 = 18/100 = 18%
b)30% is 50% of 60%
c)60% is 200% of 30%

40. a)Old price of sugar = Rs.10/-
New price of sugar = Rs.12.5/-
Old consumption = (10*100) = 1000
New consumption = (12.5*x)= 1000
x = 1000/12.5 = Rs.80/-
Decrease in consumption = 20/100*100 = 20%

b) old price = Rs.10
New price=Rs.15
10*100 = 1000
15*x = 1000
x = 1000/15 = 66.66Rs.
Decrease in consumption = 33.33%

41. a)Let my cost price be 100
Selling price = 90
Profit for Mr. X = 10
Profit % = 10/90*100 = 11.11%
b) Let cost price be 100
Selling Price = 900
My loss = 10 = 10/100*100 = 10%

42. Let cost price be 100 of both horses.
horse1 = S.P. = 110
horse 2 = S.P.= 90
Total cost price = 100+100=200
total selling price= 110+90 = 200
Hence[3]

43. Horse 1-   C.P             S.P.
x               100
?               120
S.P. = C.P.(100+profit%/100)
x = 83.33
Horse 2-          C.P              S.P.
y               100
?                 80
y = 125
Total cost price = cost price of Horse1+cost price of Horse2
= 125 + 83.33 = 208.33
Total S.P.= 100+100 = 200
loss = 8.33
% of loss = 4%
Hence[2]

44. 3 years - 2 times
6 years - 4 times
9 years - 6 times
12 years - 8 times

45. In 60 min - box is full.
In 59 min - box is half filled.
In 58 min - box is 1/4 filled.
hence[3]

2
46. A = 100(1+10/100)
= 100(110/100*110/100)
= 121

47 . Income = Rs.10/-
20%*50 = 10
capital gain = 55-45 = 10
gain = 10+10 = 20
% gain = 20/45*100 = 44.45%

48. Suppose goods cost him Rs.1/kg, then he sells goods costing Rs. 0.95 for Rs.1/-
gain = 1-0.95 = 0.05
% gain = 0.05/0.95*100 = 500/95 = 5%
Hence[1]

49. Let r be the rate of interest.
600*2*r/100 + 150*4*r/100 = 90
1200r/100 + 600r/100 = 90
r = 5
Hence[2]

50. p = Rs.455, n = 4months = 1/3 year, rate = 5%
Amount of Rs.100 = (455*1/3*5)/100 = 107.58
455                   ?
107.58             100
= 423
q = Rs.450, n = 2months = 1/6 year, rate = 5%
Amount of Rs.100 = (450*1/6*5)/100 = 103.75
450                      ?
103.75             100
= 434
Sum to be repaid to p = 434-423 = Rs.11
Hence [3]
