Solutions: 

S1. Ans.(d)

Sol.

From I

Probability of getting a black ball is = ⅙

Let there are ‘a’ black balls & ‘6a’ total balls

Similarly, red balls= ‘a’

Probability of getting a while ball = ⅔ = 4/6

There will be 4a white balls.

x = 6a

But it can’t be solved further.

From II

Probability of getting a white ball = 1 – 8/23 = 15/23

Let here 15 m white balls and 23 m total remaining balls after 1 white ball is lost

And 23m + 1 = x

15m + 1 is initial number of white balls

15 m is multiple of 15, it could be

15, 30, 45….

But it is given that initial number is less than 27. Therefore, initial number of balls is 15m + 1 = 16 balls, and now 15 balls are remaining. Hence 23 m = x – 1

Put m=1

x=24 balls

 Hence it can be answered from (ii) alone. 

S2. Ans(a)

Sol. let CP be Rs 100x & MP be Rs 100y

From I, ATQ, 80y – 100x = 100x – 60y

x : y = 7 : 10 or 7k : 10k

required profit % = 3k/7k × 100 = 42 6/7%

From II, 100x = 56y

x : y = 14 : 25 or 14k : 25k

required profit % = 11k/14k × 100 = 78 4/7%

clearly, either statement is sufficient to answer.

S3. Ans(d)

Sol. Let length of train ‘A’ and train ‘B’ be x meter and y meter respectively.

Let length of platform be z meter.

Speed of train ‘A’ and train ‘B’ be a m/s and b m/s respectively

From I,

(x+z)/a = 20

(x+z)/ (a+b) = 12

No value of z can be calculated

From II,

(y+z)/ b = 15

No value of z can be determined,

Also, speed of man is unknown

Clearly, both statements together are not sufficient to answer.

S4. Ans.(d)

Sol.

Side of the square= 56m

From I: Let the length of the rectangle be 4x m.

Then its breadth=3x m

Side of that square= {2(4x+3x)}/ 2 = 7x m

x=8 m

length of the rectangle= 32m

and breadth of the rectangle= 24m

now, we can calculate the required difference

From II: Sum of the lengths of diagonals of the rectangle = 48/60 × 100 = 80 m

Diagonals of the rectangle= 40m

now, we can calculate the required difference

Hence, the question can be answered by using either of the two statements.

S5. Ans.(c)

Sol.

Let the ten’s place and unit’s place digits of the number be x and y respectively.

And, the number= (10x + y)

From I:
x + y  = 0.25 (10x + y)

⟹ y = 2x

From II:  3(10x + y) – (10y + x) = 30

⟹ 29x – 7y = 30

Hence, Both the statements together are sufficient to answer the question.

S6. Ans.(d)

Sol.

Let the marked price and cost price be Rs 80x and Rs 50x respectively

From I: Selling price= 80x × 4/5 × 9/10  = Rs. 57.6x

And 16x – 6.4x = 192

x=20

SP = Rs 1152

From II: MP-CP=Rs 600

80x-50x=600

Marked price= Rs 1600

And cost price= Rs 1000

Selling price= Rs 1152

Hence, either of the two statements is sufficient to answer the question

S7. Ans(c)

Sol.

Let number of employees who like only coffee be x

And, number of employees who like both coffee and tea be y

And, number of employees who like only tea be z

Given, (x + y + z) = 300 ——– (i)

From Statement I

(x + y) = 55/100 × 300

(x + y) = 165

From equation (i)

165 + z = 300

z = 135

From Statement II –

(y + z) = 70 × 300/100 = 210

(y + z) = 210

From equation (i)

x + 210 = 300

x = 90

From I & II together

x + z = 135 + 90 = 225

So, both the statements taken together are necessary to answer the questions.

S8`. Ans.(b)

Sol.

From I

Probability of getting a black ball is = ⅙

Let there are ‘x’ black balls & ‘6x’ total balls

Similarly, red balls= ‘x’

Probability of getting a while ball = ⅔ = 4/6

There will be 4x white balls.

a = 6x

But it can’t be solved further.

From II

Probability of getting a white ball =  1 – 8/23 = 15/23

Let here 15 m white balls and 23 m total remaining balls after 1 white ball is lost

And 23m + 1 = a

15m + 1 is initial number of white balls

15 m is multiple of 15, it could be

15, 30, 45….

But it is given that initial number is less than 27. Therefore, initial number of white balls is 15m + 1 = 16 balls, and now 15 balls are remaining. Hence 23 m = a – 1

Put m=1

a=24 balls

 Hence it can be answered from (ii) alone. 

9. Ans(b)

Sol. In  (61/x ÷ 61/y) = (61/x-1/y)

Statement I – Given, reciprocal of x is 1/48 more than that of y

1/x – 1/y = 1/48

So, (61/x ÷ 61/y)  = 61/48

Statement II – given, Product of reciprocal of x & y is 1/192

1/x × 1/y = 1/192

xy = 192

From Statement II, we can’t determine the value of (61/x ÷ 61/y).

So, Only Statement I alone sufficient to give answer of the question.

S10. Ans(d)

Sol.

From I – Cone height = 12 cm

From II –

Let radius of larger sphere be ‘3x’

So, radius of smaller sphere be ‘2x’

From III –

Radius of cone = 3x × 5/6 = 15x/6

And, difference between volume of both spheres is 13336/ 21 cm3

From II & III

(27x3 –  8x3) =

x = 2cm

using I, II, III lateral surface area of cone can be determined

So, all given statements together are required to answer

S11. Ans.(e)

Sol.

                                    Veer   :           Satish :           Yogesh

Satish              :                       Veer

From (B and C)            8000×9                       :           6000×12

1                      :                       1

Share of Veer share of Satish = Rs 900

Either A and C or B and C question can be solved.

S12. Ans.(d)

Sol. From A: l : b = 3 : 2

From B: length- breadth= 16 m

Cost of flooring = 50 per sq m

l = 48 m

b = 32 m

Area = 48 × 32 sq m

Required price = 48 × 32 × 50

From C: perimeter = 160 m

Length = 3 × 16 = 48 m

Breadth = 16 × 2 = 32 m

Required cost = Rs. 48 × 32 × 50

we can get the cost of flooring a rectangular hall using any of the two statements.

S13. Ans.(d)

Sol.  From A: Let the length of second and first train be  m respectively

From B: Let speed of first and second train be 2y m/s and 3y m/sec

From C: Speed of first train = 36 km/hr= 10 m/s

As we don’t know the directions of their motion so relative speed can’t be determined

S14. Ans.(b)
Sol.

From A: let the diagonals be 3x m and 4x m.

From B: Side of square= 40 m

Perimeter of rhombus= perimeter of the square= 160 m

From C:

x = 8, diagonal = 24, 32

Area =

So, using any two of the given three statements we can find area of the rhombus.

 

S15. Ans.(e)
Sol.

From A: History+ English +Maths=210

From B: Either History-English= 10 or English-History=10

From C:  Biology+ Maths=120

So, marks of maths can’t be determined using the given information

 

S16. Ans.(c)

From A:

From B:

From C: 

 

 

S17. Ans(e)

Sol.

From I –

– 1]

So, From I we can get the value of R

From II –

 

And,

 

From equ. (i) and (ii), we can get the value of R.

From III – From III we can get two variables first Amount ‘Q’ and second Rate of interest ‘R’. So, we can’t determine the value of two variables from one equation.

So, either statement (I) or statement (II) alone is sufficient to answer the question

 

S18. Ans(d)

Sol.

Given, marked price of pen = Rs. Y

From I – We can’t know the cost price of pen. So, we can’t determine marked up how much percentage above its cost price.

From II – Give, Cost price of pen = Rs. x

So, selling price of pen = Rs. 1.08x

And given, shopkeeper allows a discount of 4% on marked price

So, 96% = Rs. 1.08x

100% (marked price) = 1.125x Rs.

ATQ –

1.125x – x = 28

x = 224

Marked price of pen (Y) = 1.125

So, from II we can determine the value of Y.

From III – Given, cost price = Rs. P

And, selling price of pen = Rs. (P + 70)

ATQ –

Marked price of pen =

From I & III –

P

12.6P – 9P = 630

3.6P = 630

P = 175

So, marked price of pen (Y) =  Rs.

So, either statement (II) alone or statement (I) and (III) together sufficient to answer the question.
