Direction: Answer the questions based on the information given below: 

Rahul goes to gym and runs 40 minutes on treadmill. For starting 15 minutes he runs at a uniform speed of 5 km/hr and after that he runs at a uniform speed of 9km/hr for remaining time. He runs total (A) km on treadmill. After that he comes to his house and get ready for office which is 45km away from his house. He reaches office in 1.5 hours at 9:30 a.m. In office he gives some work to his subordinates P1 and P2 at (B). P1 can complete that work in 6 hours while efficiency of P1 and P2 is in the ratio 5: 4. P1 and P2 together completes 75% of that work at 12:30 p.m. Rahul and P2 together can complete same work in 3 hours. Rahul is (C) % more efficient than P1. After that work he comes back to home in upstream (Speed of stream is 3km/hr and his speed in still water and distance between his house and office are same as earlier). He takes (D) hours to reach home. When he reaches home, two of his friends Aman and Raman come at his house, all three starts to play a game in which 2 dices are used by each person.  When only Rahul & Aman are playing, (E) was the number of outcomes in which first Rahul and then Aman throw their respective dices. In a game, all three throw their dices and each one of them get 8 as the sum of numbers in their dices and any one of two not get same outcomes.

SOLUTIONS:

ARITHMETIC SUM

1.Let amount of milk removed = 2x litre

So, amount of water added = x litre

Now → (165 − 2𝑥)/𝑥 = 5/3

x = 45 lit

2.At least one black can be chosen in two ways from each box:

Now, probability of choosing at least one black ball from first box = 1/2 × [ (2C1× 2C1)/4C2 + 2C2/4C2 ]= 5/12

Probability of choosing at least one black ball from 2nd box = 1/2 × [(4C1×12C1)/16C2 + 4C2/16C2] = 9/40

Final probability = 5/12 + 9/40 = (50 + 27)/120 = 77/120

3.Let speed of train B be 𝑥 m/s And length of train B be 𝑦 m

Then length of train A is 2𝑦 m

Speed of train A = 84 × 5/18 = 210/9 m/s = 70/3 m/s

A.T.Q, (2𝑦+𝑦)/10 = (70/3) − 𝑥 ………….(i)

and (2𝑦+𝑦)/ 22.5 = (70/3) − 2𝑥 …………….(ii)

solving (i) and (ii), 𝑦 = 50 m

4.Let, inner radius of cylinder be ‘𝑥’ cm.

4/3 𝜋(6)3 = 𝜋 × 32 (52 − 𝑥2 )

or, (4 × 6 × 6 × 6) / (3 × 32) = 25 − x2

or, 𝑥2 = 25 − 9

or, 𝑥 = 4 cm

Hence, thickness = 5 – 4 = 1 cm.

5.Profit ratio X & Y = (700 × 3) + (700 × 5/7 × 3) + (700× 5/7 + 200 × 3/5 )× 6 : 600 × 12

X:Y= 7320 : 7200= 183:180

∴ X’s share from profit = 183 × 726 /(183+180) = 𝑅𝑠. 366.

6.C.P. of 10 note books ⇒ 140 × 10 = 1400 Rs.

Profit on selling one pen ⇒ 50×200/100 = Rs 100

Number of pen required ⇒ 1400/100 = 14

7.Let speed of slower train = 2x

⇒ speed of faster train = 5x

ATQ, (150 + 200)/(2x + 5x) = 15

x = 10/3

Time required = 350 /[50/3 – 20/3] = 35 seconds

8.Let length and breadth of rectangle be L cm and B cm respectively So, ATQ

Area1= (L-6)×B

But this is square, so L-6=B

Area1= (L-6) × (L-6)

Case 2, Area2= L × (B+6),

L=B+6

So, Area2= L × L,

Given, Area2-Area1= 252

(L)2-(L-6)2=252

Solving this, L= 24

B= 18

Perimeter= 2(L+B)= 2(24+18)= 84 cm

9.Diagonal of Square = Side √2= 2.5√2 × √2 = 5 cm

Breadth = 5 cm

Length of rectangle = 5 × 3 = 15 cm

Area of rectangle = 15 × 5 = 75 cm2

10.let speed of boat= X, speed of stream= Y

Upstream speed= X-Y

Downstream speed= X+Y

Sum of upstream & downstream= (X-Y) + (X+Y)= 2X

So, 2X= 40

X= 20 km/hr

Speed of boat : speed of stream= 600+100 : 100= 7:1

So speed of Stream= 20/7 km/hr

ATQ, D/( X-Y) + D/( X+Y) = 5

D/(120/7) + D/(160/7)= 5

D= 480×5/49= 48.97 km= 50 Km(approx)

11.Ratio of profit,

A : B = (800 × 8+ 900+ 1000+ 1100+ 1200) : (1600 × 8+ 1700+ 1800+ 1900+ 2000)

A : B = 53 : 101

Profit of A ⇒ 7700 ×53/154 = 2650 Rs.

12.Let initial investment of A = x

Ratio of profit A : B : C = 12 × x : 6×4500 : 4×4500

A :B:C = x : 2250: 1500

Now ATQ

x/(x+2250+1500) = 4900/10000

solving this we get,

x ≈ Rs 3600

DATA SUFFICIENCY:

13.From I, II & III

Let speed of Amit and Abhi be 4x and 5x km/hr respectively.

5x – 4x = 20

∴ x = 20 km/hr

So speed of Abhi= 20×5= 100 km/hr

Speed of Amit= 20×4= 80 km/hr

Let distance be D km

D/80 – D/100 = 1

∴ D = 80 × 100/20 = 400 km

All I, II and III required to answer.

14.From I and II, Let length and breadth be 3x m and 2x m respectively

2πr = 440 [r → radius of circle]

r = 70 m

∴ breadth = 70 ×1/7 =10 m

& length = 15 m

∴ Area = 10 × 15 = 150 m²

From statement III, length : breadth= 150 : 100= 3:2

So Statement I and III are same.

Only II and either I or III required to answer.

15.From statement I, Passed = 400

From statement III, Let number of appeared & Failed students be 5x and 3x respectively

2x = 400

⇒ x = 200

∴ failed = appeared – passed = 1000 – 400 = 600

So, Only I and III required to answer.

16.From statement I, PR × 2/100 = 44000

PR = 2200000…….(i)

From statement II, P + PRT/100 = 154000..................(ii)

From statement III, Difference = PR2/1002

PR2/1002 = 120………(iii)

by solving (i)&(iii) R can be found.

Only I and III required to answer

17.Let the smaller no. is x & bigger no. is y.

From statement I, y = x + 6

From statement II, (40/100) × 𝑥 = (30/100) × 𝑦

From statement III, 𝑦/2 : 𝑥 /3 = 2 : 1

⇒ 3y = 4x

statement II & From statement III give only ratio between the numbers, so we statement I also along one of II or III.

∴ from I and II or I and III we can find the Answer.

CASLET  EXPLANATION:

Rahul runs 40 minutes. 
For starting 15 minutes 
Speed = 5 km/hr 
Distance =  15/60 × 5 = 5/4km 
For next 25 minutes 
Speed = 9 km/hr 
Distance = 25/60 × 9= 15/4  km 
Total distance =  5/4 +  15/4 = 5 km
So, he runs total 5 km on treadmill. 
P1 can complete that work in 6 hours 
Efficiency of P1 and P2 = 5: 4. 
So, P2 can complete the work in 
 6 * 5/4=7.5hours 
So, the number of units of work done by them in one hours =  1/6 +1/7.5 = 3/10
So, they together can complete the work in
10/3 hours 
P1 and P2 together complete 75% of that work at 12:30 p.m. 
100% of the work is completed in 10/3 hours 
So, 75% of the work will be completed in 10/300 * 75 = 2.5hours 
So, in office Rahul gives some work to his subordinates P1 and P2 at 12.30 – 2.5 hours = 10 am. 
Rahul and P2 together can complete same work in 3 hours. 
 1/Rahul + 1/7.5 = 1/3
Rahul = 5 hours
 
So, Rahul can complete the whole work in 5 hours 
Also, P1 can complete that work in 6 hours 
So, ratio of the efficiency of P1 and Rahul = 6: 5 
So, required percentage =  (6-5)/5 * 100 = 20%
So, Rahul is 20 % more efficient than P1. 
Distance between house and office = 45km. 
Time taken to reach office = 1.5 hours at 9:30 a.m. 
Speed =  44/1.5 = 30 km/hr
Speed of stream = 3km/hr 
Therefore, required time =  45 /( 30 -3 ) = 45/27 = 5/3
So, he takes 1 2/3 hours to reach home. 
Total outcomes in a single throw of 2 dice = 
(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6) 
(2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6) 
(3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6) 
(4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6) 
(5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6) 
(6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6) 
So, total number of outcomes in a single throw of two dice = 36 
When first Rahul and then Aman throw their respective dices, total number of outcomes = 36 + 36 = 72 
In a game, all three throw their dices and each one of them get 8 as the sum of numbers in their dices and any one of two not get same outcomes. 
So, the required possibility = (2, 6) (3, 5) (4, 4) (5, 3) (6, 2) 
Winner is the one who gets highest number as the sum of the square of the number comes in dices. 
(2, 6) =  2² + 6² =40
(3, 5) =  3² + 5² = 34
(4, 4) =  4² + 5²= 32
(5, 3) =  5² + 3²=34
(6, 2) =  6² + 2²=40
So, Raman will get (2, 6) and the other two will get (3, 5) and (4, 4) 
So, he runs total 5 km on treadmill. 
So option (c) is the correct answer.
