Solution:
1. C) Let total person travelling through Delhi metro in all six days = 10x
So total person travelled through Mumbai metro in all six days = 9x
According to condition
10x/100 × 50/3 – 9x/100 × 40/3 = 70
=> 500x – 360x = 70 × 300 => 140x = 21000
=> x = 150
Total person travelled through Delhi metro in all six days = 1500
Total person travelled through Mumbai metro in all six days = 1350
Total fare of Delhi metro on Saturday = 35/300 × 1500 × 18 = Rs.3150
Total fare of Mumbai metro on Saturday = 5/27 × 1350 × 20 = Rs.5000
Required difference = Rs.1850
2. E) ATQ,
(35/300 × 1500 – x)/(5/27 × 1350 – x) = 2/3
=> (175 – x)/(250 – x) = 2/3
=> 525 – 3x = 500 – 2x
=> x = 25
3. A) Total people travelling in Delhi metro on Wednesday and Thursday
= (10x/100) × (50/3 + 50/3) = 10x/3
Total people travelling in Mumbai metro on Monday and Saturday together
= 9x/100 × (200/9 + 500/27) = 11x/3
Required percentage= [(10x/3)/(11x/3)] × 100 = 1000/11% = 90 10/11%
4. C) Persons travelled on Delhi metro on Monday = 1500 × 70/300 = 350
Persons travelled on Mumbai metro on Saturday = 1350 × 500/2700 = 250
Let fare per person of Delhi metro and Mumbai metro is 10x and 9x respectively.
Required percentage = [(350 × 10x – 250 × 9x)/250 × 9x] × 100 = 1250x/2250x × 100 = 55 5/9%
5. D) Total persons travelling both metro on Sunday = 120/100 × 15 × 35/3 + 130/100 × 13.5 × 500/27 = 210 + 325 = 535
Total persons travelled by both metro on Monday = 15 × 70/3 + 13.5 × 200/9 = 350 + 300 = 650
Required percentage = 535/650 × 100 = 82 4/13%
6. A) Let Sum = x
Differnece = P  (r/100)^2 × (300 + r)/100
=> 220.32 = P × (6/00)^2 × (300 + 6)/100
=> P = (220.32 × 100 × 100 × 100)/(6 × 6 × 306)
=> P = Rs. 20000
7. D) Let cost price of the tealeaves be Rs t
Then as per the condition
t × 117.5/100 + 11.55 = t × 92/100 × 130/100
=> t = [11.55/(0.92 × 130 – 117.5)] × 100 = Rs.550
8. D) Let speed of boat be b km/hr
And speed of stream be c km/hr
Then downstream speed = (b + c) km/hr
And upstream speed = (b – c) km/hr
As per the condition,
[(b + c) + (b – c)]/2 = 15
=> 2b = 30kmph => b = 15kmph
Also, 3 + 12/60 = 57.6/(b + c)
On solving b + c = 18
c = 18 15 = 3 km/hr
Time required in covering a distance of 480 km upstream = 480/(15 – 3) = 40 hours
9. E) Let age of younger sister five years ago = x yrs
hence, age of elder sister five years ago = x + 8 yrs
Average = (x + x + 8)/2
=> 27 × 2 = 2x + 8
=> 54 – 8 = 2x
=> 2x = 46
=> x = 23
Present age of younger sister = 23 + 5 = 28 years
Present age of elder sister = 23 + 8 + 5 = 36 years
Average age after 5 years = (28 + 36 + 10)/2 = 37 years
10. B) Let Investment = 18x, 20x, 21x, 28x
New ratio = (18x × 4) + (18x × 120% × 6) : (20x × 4) + (20x × 130% × 6) : (21x × 4) + (21x × 125% × 6) : (28x × 4) + (28x × 140% × 6)
= (72x + 129.6x) : (80x + 156x) : (84x + 157.5x) : (112x + 235.2x)
= 201.6 : 236 : 241.5 : 347.2
Total profit = (14490/241.5) × 1026.3 = Rs.61578
11. A) From Statement I:
Cost price of a shirt = 1100 Rs.
Selling price = 1100 + 55 = 1155 Rs.
Marked price = 1155 / 77 × 100 = 1500 Rs.
Statement I is sufficient to answer the question.
From Statement II:
Let the cost price = x Rs.
Marked price  = x × 136% = 1.36x
Selling price = x + 200
Statement II is not sufficient to answer the question.
12. A) From Statement I:
Let Anuj = 4x, Vipin = 5x
Sanjeev = 4x + 4
From Statement II:
Anuj = 20 years, Sanjeev = x, Vipin = x + 1
Statement III:
Let age of Mohan = m years
Sanjeev = m - 5 years
From Statement I + Statement II:
Anuj = 20 years, Vipin = 20/4x × 5x = 25 years
Sanjeev = 25 – 1 = 24 years
Statement I and II both are necessary to answer the question.
13. E) From Statement I:
Time = 25 seconds
Relative speed = length of trains/25
From Statement II:
Length of train Y = 320m
Difference of speed = 14 km/h
From Statement III:
Let the speeds = 19x, 26x
Statement I + Statement II + Statement III
26x – 19x = 14
7x = 14
x = 2
Speed = 52 km/h, 38 km/h
(52 + 38) × 5/18 = (a + 320)/25
25 × 25 = a + 320
625 – 320 = a
a = 305 m
Therefore, all the statements are necessary to answer the question.
14. A) From Statement I:
Let radius = r, height = h
Curved surface area = 2πrh
396 = 2 × 22/7 × r × h => rh = 63
Total Surface area = 2πrh + 2πr2
1628 = 22/7 (rh + r^2)
=> (rh + r^2) = 259
63 + r= 259
r= 259 - 63 = 196
r = 14
r × h = 63
14 × h = 63
h = 4.5 cm
Statement I is alone sufficient to answer the question.
From Statement II:
r = 3h + 0.5
Statement II is not alone sufficient to answer the question.
15. C) From Statement I:
Let sum = x ?, rate = y%
x = x × 12.5 × y%
y = 8%
Statement I is alone sufficient to answer the question.
From Statement II:
A = P (1 + r/100)^t
=> 5832 = 5000 (1 + r/100)^2
Statement II is also alone sufficient to answer the question.
