=180000
Given A=B+C
Therefore A+B+C=180000
A+A=180000
2A=180000
A=90000
Given B/C=2/1
B=2C
B+C=90000
B+(B/2)=90000
3B/2 =90000
B=30000*2
B=60000

let the total number of apples be ‘p’
In the 1st week he ate 0.6p and thrown away 0.15p
Therefore after 1st week apples left=p-(0.6p+0.15p)
=0.25p
In the second week he ate 0.125p and thrown away (0.25)*(0.2)*p=0.05p
Therefore after 2nd week apples left=0.25p-(0.125p+0.05p)
=0.25p-0.175p
=0.075
Total apples eaten =0.6p+0.125p+0.075p
=0.8p
Total apples thrown away=0.2p
Therefore 0.2p=500
p=2500
Total apples eaten =0.8*2500
=2000

Here the pattern consists of 2 different series in AP
i.e 2,1,0,-1,… and the other 3,4,5…..
10th term in 2,1,0,-1,… is -7
10th term in 3,4,5….. is 12
Sum of 1st series is 3-((7*8)/2)=3-28=-25
Sum of 2nd series is (12(13)/2)-3=78-3=75
Sum=50
Average=50/20
=2.5

Let the length of the train B be $T_B$ metres
Length of the platform which B crosses = 210 metres
Time taken to cross the platform = 5 seconds
Speed of train B = 252 km/hr = $252\times\dfrac{5}{18} = 70$ m/sec

$\dfrac{T_B + 210}{5} = 70$

=> $T_B + 210 = 350$
=> $T_B = 140$
Therefore, Length of the train B = 140 m
Then, Time taken by train B to cross the man = $\dfrac{140}{70} = 2$ seconds

Let the length of the train D be $T_D$ metres
Length of the platform which D crosses = 200 metres
Time taken to cross the platform = 9 seconds
Speed of Train D = 144 km/hr = $144\times\dfrac{5}{18} = 40$ m/sec

$\dfrac{T_D + 200}{9} = 40$

=> $T_D + 200 = 360$
=> $T_D = 160$

Therefore, Length of the train D = 160 metres
Time taken by the train D to cross the man = $\dfrac{160}{40} = 4$ seconds

Therefore, Average time taken by all the trains to cross the man = $\dfrac{6+2+3+4+5}{5} = \dfrac{20}{5} = 4$ seconds

Speed of train A = 198 km/hr = $198\times\dfrac{5}{18} = 55$ m/sec
Length of train A = 55*6 = 330 m
Length of platform which A crosses = 360+25 = 385 metres
Then, Time taken by A to cross the platform = $\dfrac{330+385}{55} = \dfrac{715}{55} = 13$ seconds.

Let the length of the train B be $T_B$ metres
Length of the platform which B crosses = 210 metres
Time taken to cross the platform = 5 seconds
Speed of train B = 252 km/hr = $252\times\dfrac{5}{18} = 70$ m/sec

$\dfrac{T_B + 210}{5} = 70$

=> $T_B + 210 = 350$
=> $T_B = 140$
Therefore, Length of the train B = 140 m
Then, Time taken by train B to cross the man = $\dfrac{140}{70} = 2$ seconds

Let the length of the train D be $T_D$ metres
Length of the platform which D crosses = 200 metres
Time taken to cross the platform = 9 seconds
Speed of Train D = 144 km/hr = $144\times\dfrac{5}{18} = 40$ m/sec

$\dfrac{T_D + 200}{9} = 40$

=> $T_D + 200 = 360$
=> $T_D = 160$

Therefore, Length of the train D = 160 metres
Time taken by the train D to cross the man = $\dfrac{160}{40} = 4$ seconds

Therefore, Required difference = 4-2 = 2 seconds.

From the given information the time period is 18-15=3 years
So the money is distributed in the ratio 4:5 i.e On 1st son it is (4/9)*360000=160000
On the second son it is (5/9)*360000=200000
Interest for 1st son=160000*3*5/100
=24000
Interest for 2n son=200000*3*5/100
=12000
=184000
=212000
Difference=212000-184000
=28000

Given CP per dozen=300
For each apple cost=300/12
=Rs 25
Total cost price of apples=200*25
=5000
He sold 40% of apples at Rs 30 per each
So (40/100)*200 =80 apples
80*30=Rs 2400
25% of remaining apples are spoiled i.e (3/5)*(1/4)*120=18 apples
So total leftover apples=120-18
=102
So 51 apples are sold at 40 per each and the other 51 apples at 35 per each
Therefore total CP=51*40+51*35
=2040+1785
=Rs 3825
Total CP=3825+2400
=6225
Profit percent=((6225-5000)/(5000))*100
=1225/50
=24.5 %

Let the cost price of A,B and C be a,b and c
SP of A=1.1a
SP of B=1.2b
SP of C=1.3c
Total SP=1.1a+1.2b+1.3c
Total CP=a+b+c
Aso given a+b=2c
a-b=0.4a
b=0.6a
a+b=2c
1.6a=2c
c=0.8a
Total SP=1.1a+1.2(0.6a)+1.3(0.8a)
=1.1a+0.72a+1.04a
=3.86a
Total CP=a+0.6a+0.8a
=2.4 a
Total profit percent=((3.86a-2.4a)/(2.4a))*100
=60.8%

The ratio of profit is given by,

= $(\frac{1}{5} \times \frac{1}{5} \times \frac{1}{7}) : (\frac{2}{3} \times \frac{2}{3} \times \frac{3}{200}) : (\frac{3}{2} \times \frac{3}{2} \times \frac{5}{200})$

= $\frac{1}{175} : \frac{1}{50} : \frac{9}{160}$

The profit of A =

Let the initial volumes of X,Y and Z be 5x,7x and 4x respectively
Now let ‘a’ amount of X is added to the solution
Let ‘b’ amount of Y is added to solution
Let the final volume of each liquid X,Y and Z be 3y,2y and y respectively
As the volume of Z is not changed we have 4x=y
New volume of X=5x+a
New volume of Y=7x+b
Therefore we have 5x+a=3y
5x+a=12x
a=7x
7x+b=2(4x)
b=8x-7x
b=x
Ratio of a:b=7:1

Let the initial volumes be A,B and C
A=15 litres
B=7x and C=2x
A=15+5+4=24 litres
B=7x-5
C=2x-4
Given 24/(7x-5)=4:5
120=28x-20
28x=1440
x=5 litres
B=7(5)-5=30 litres
C=2(5)-4=6 litres
Total volume=24+30+6=60 litres

Let ‘r’ be the common ratio of the given GP.
The ratio of 3rd and 6th term of a GP is 27.
$\dfrac{ar^2}{ar^5}$ = 27
$\Rightarrow$ $\dfrac{1}{r^3}$ = 27
$\Rightarrow$ $r = \dfrac{1}{3}$
Sum of infinite GP = $\dfrac{a}{1-r}$ = $\dfrac{10}{1-1/3}$ = 15
Hence, option C is the correct answer.

Let ‘a’ and ‘d’ be the first term and common difference of the given AP.
$\Rightarrow$ $\dfrac{3}{2}(2a + 2d) = \dfrac{2}{9}[\dfrac{6}{2}(2a + 5d)]$
$\Rightarrow$ $3a+3d = \dfrac{2}{3}(2a + 5d)$
$\Rightarrow$ $9a+9d = 4a + 10d$
$\Rightarrow$ $5a = d$
$\Rightarrow$ $\dfrac{a}{d} = \dfrac{1}{5}$
Therefore, option E is the correct answer.

N leaves the same remainder on dividing 2527, 2419, 2383, and 2599, the difference between any pair of these numbers should be divisible by the number. The smallest difference will be the limiting factor.
2599 – 2527 = 72
2599- 2419= 180
2599-2383= 216
2527- 2419= 108
2527- 2383= 144
2419- 2383= 36
As we can see, 36 is the smallest difference and hence, the largest number that satisfies the given condition is 36.
Therefore, option D is the right answer.

Length = 5 m , Breadth = 3 m and Height = 8 m

To find the cost of painting the walls of the room, we should know the cost of painting and the area of door and window.

Area of 4 walls (Curved Surface Area of cuboid) = $2h(l+b)$

= $(2 \times 8)(5+3) = 16 \times 8 = 128$ $m^2$

From I & II : Cost = Rs 25 per square meter

Area of window = $2.25$ $m^2$

and Area of door = $2 \times 2.25 = 4.5$ $m^2$

Thus, area to be painted = $128 – 2.25 – 4.5 = 121.25$ $m^2$

$\therefore$ Cost of painting 4 walls = $25 \times 121.25 = Rs$ $3031.25$

Thus, statement III is redundant.

=> Ans – (C)

To find the time taken by train X to cross train Y, we should know the sum of speed of the trains (as they are moving in opposite directions) and the sum of lengths of the train

In statement II, ratio of speed of train X : Y = 3 : 2

Thus, we cannot find the speeds of the two trains.

$\therefore$ Data is inadequate

=> Ans – (E)

Ratio of investment of X : Y : Z = 5 : 4 : 2

To find the share of profit earned by X (or anyone), we need to find the total profit earned.

From statement III : Average profit for 3 years = Rs. 2750

=> Total profit = $2750 \times 3$ = Rs. 8250

Amount received by X = $\frac{5}{(5+4+2)} \times 8250$ = Rs. 3750

Thus, statements I and II are redundant.

=> Ans – (D)
