ANSWERS
 (1)A
 LCM of 3,4,5,6 and 8=120.Now,by seen the option we get that 14400 is a least five digit perfect square number which is divisible by 120

 (2)B
  it follows 1+4,next one 1+9,2+9 in same way 44+(4+4)=52 not 51

 (3)B
 given S.P of table =30 profit percentage = 20% CP of table =(30*90)/10 =27 required profit percentage = (27-25)/25 *100 =8%

 (4)C
 Here, a=10L, n=2 and x=100L
Quantitiy of wine in end =x(1-a/x)^n
                                        =100(1-10/100)^2
                                        =81L
 Required ratio =81:(100-81)=81:19

 (5)D
 Let the marks of A,B and C are 10x,12x and 15X respectively.
 maximum marks of C=15*6=90 and maximum marks of
 b=12*6=72 hence the marks of B cannot be in the range of (80-90)

 (6)B
 Let CP=Rs 1000
 Actual CP=Rs 920 and selling price =(1000*115)/100 = 1150
 Actual profit percentage = (1150-920)/920 * 100% =25% ans

 (7)D
 Perimeter of circular sheet = 2πr =20π cm
 The perimeter of base of conical surface = 20π*(100-40)/100 =12π
  Radius of base of conical surface = 12π/2π = 6cm
  & the height of conical surface =  √(10^2-6^2)=8cm
  so,The required ratio = 6:8 or 3:4

 (8)B
  x= sinθ+cosθ y= Secθ+cosecθ
    =1/sinθ+1/cosθ
    =sinθ+cosθ/sinθcosθ
    =x/sinθcosθ........2
  (sinθ+cosθ)^2=1+2sinθcosθ
     x^2=1+2sinθcosθ
     sinθcosθ=(x^2-1)/2 from equation .....2
     y=2x/x^2-1 ans

(9)B
sinθ+cossecθ=2
sinθ+1/sinθ =2
sin^2θ+1=2 sinθ
(sin^2θ-2sinθ+1)=0
(sinθ-1)^2=0
sinθ=1=sin90°
θ = 90°
so,sin^7θ+cosec^7θ=1+1 =2ans

(10)A
 f(θ)=sin^8θ+cos^14θ
       =sin^8θ+(1-sin^2θ)^7
 f(90°)=1+(1-1)^7
           =1

Answers with Explanation:-

1.(4) Marks of T = 75
Marks of R = 65
Marks of Q = 110
Marks of P = 85
Marks of U = 120
Maximum marks = 200
Required percentage = 120/200 x 100 = 60%

2.(2)Let the capacity of the tank be 30 litres.
So Pipe A can fill 3 litre/hour, Pipe B can fill 2 litre/hour and Pipe C can empty 1 litre/hour.
Together they can fill = 3 + 2 – 1 = 4 litre/hour
Tank filled in 6 hours = 24 litres
Time to fill the remaining tank by pipe A alone = 6/3 = 2 hours

3.(4)Let the largest and smallest angles be x and 3x. Now
x + 3x + 56 = 180
x = 31
largest angle = 93°.

4.(4)3W = 2M
21 W = 14 M
Let the required number of days be x.
N1 D1 H1 = N2 D2 H2
15 X 21 X 8 = 14 X 6 X x
X = 30 days

5.(2)CP of first item = Rs. 52000
Selling price of second item = 52000 x 0.75 x 1.4
His overall profit = 54600 – 52000 = 2600


6.    (4) 
Total Students in school = 3600
Number of boys = 4/9 x 3600 = 1600
Number of boys who like hockey = 20% of 1600 = 320
Number of girls = 2000
Number of girls who like hockey = 60% of 2000 = 1200
Number of students who do not like hockey = (1600 – 320) + (2000 – 1200) = 2080 

7.    (1)
Let the present ages of Sonu and Monu be 7x and 6x. Now
7x – 8 /6x – 8 = 5/4
x = 4
Present age of Monu = 24 years
Monu’s age four years from now = 24 + 4 = 28 years

8.    (2)
 Let the numbers be x, x + 2 and x + 4. Then
x + (x + 2) + (x + 4) = x + 20
x = 7
So the middle number is 9.

9.    (3)
 The ratio of their investments = 24000 x 12: 31000 x 8 : 40000 x 6 = 36 : 31:30
Since the ratio of investment is also the ratio of profit,
C’s share = 30/97 x 12028 = 3720

10.  (2) 
2 M x 6 = 2 W x 9 = 3 C x 8
2 M = 3 W = 4 C
The ratio of efficiency of man, woman and children = 1/2: 1/3: 1/4 = 6: 4: 3
Let the work done by a man, a woman and a children in one day be 6 units, 4 units and 3 units respectively.
So the total work to be done = 2x6x6 = 72 units
Work done by 3 women and 4 children in one day = 3 x 4 + 4x 3 = 24 units
Remaining work = 72 – 24 = 48 units
Number of men required to complete the remaining work in one day = 48/6 = 8

      A. Rs.200
      B. Rs.300
      C. Rs.400
      D. Rs.600

Answers with Explanation:-
1.    (B):
      Ratio capital of Anil, mukesh and Ritesh.
      = ( 20,000 x 4 + 14000 x 8 ) : ( 20,000 x 4 + 12000 x 8 ) : ( 20,000 x 4 + 26000 x 8 )
      = 192000 : 176000 : 288000
      Anil share = (65600 x 192 / 656 ) = 19200
      Mukesh share = ( 65600 x 176 / 656 ) = 17600
      Ritesh share = (65600 x 288 / 656 ) = 28800

2.    (A):
      Step 1: we can assume that amar join into business after x months.So amar money was invest into (12 – x ) months.
      Step 2: 76000 x 12 / 57000 x ( 12 – x ) = 2 / 1
      912000 = 114000 ( 12 – x ) = 114 ( 12 – x ) = 912 = x = 4
      After 4 months amar join the business.

3.    (A):
      Short tricks :   Samir : Nitish share of capital
      = ( 40,000 x 36 ) : ( 60,000 x 30 ) =  1440000 : 1800000 = 4 : 5 .
      Samir’s share is =  Rs . 27900 x 4 / 9 = Rs. 12400.

4.    (B):
      Ration of share Anil, Mukesh and Ritesh = Ratio of their investment
      Anil : Mukesh : Ritesh = 125000 : 150000 : 175000 = 5 : 6 : 7
      Anil share = Rs. [93600 x 5 / 18 ] = 26000.
      Mukesh share = Rs. [93600 x 6 / 18 ] = 31200.
      Ritesh share = Rs. [93600 x 7 / 18 ] = 36400

5.    (D):
Short tricks : Let the initial investment money ratio of Jon and Harry is 2x and 3x So Jon , Harry and Ron ratio of investment is ( Jon : Harry : Ron ) = (2x X 12 ) : ( 3x X 12 ) : ( 3x X 6 ) = 24 : 36 : 18 = 4 : 6 : 3 

6.    (B):
      Suppose Ramesh invested Rs. x. Then,
      Manoj : Ramesh = 120000 * 6 : x *12.
      720000/12x: 6000/3000
      x = 30000

7.    (D):
Just take care of the months of investment, rest all will be simple.
      Yogesh:Pranab:Atul = 45000*12:60000*9:90000*3 = 2:2:1
      Atul's share = Rs. 20000 * (1/5) = Rs. 4000

8.    (D):
A:B = 3:2 = 6:4
      A:C = 2:1 = 6:3
      A:B:C = 6:4:3
      B share = (4/13)*157300  = 48400

9.    (D)
      Let the amount invested by Ramesh = Rs.x.Then, 20000×6 : 12x=6000:3000
      or 12000012x=21 or x = 5000

10.  (C)
      Let C's share = Rs.x. Then
      B's share = Rs.x2
      And, A's share = Rs.x4
      A:B:C = x4:x2:x=1:2:4

      Hence, C's share = Rs.(700×47) = Rs.400
