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)

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.

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
