EXPLANATIONS
1. (c) Let the present age of father is x and son is y. According to the question, 10 years ago, x - 10 = 7/2 (y-10)
⇒ 2x - 20 = 7y - 70
⇒ 7y - 2x = 50 (i)
10 years from now, x + 10 = 9/4(y + 10)
⇒ 4x + 40 = 9y + 90 (ii)
On solving both the equations
We get, y = 30 and x = 80
Sum of their present ages = 80 + 30 = 110 years
2. (d) Moving in the clockwise direction, Cube 1-3,1,5 Cube 2-3,4,2 Clearly, 6 will be opposite to 3.
3. (c) According to question, 10×2 - 2 = (20 - 2) = 18
18×2 + 2 = (36 + 2) = 38
Similarly, the option(c) is related to above number set in this manner.
12×2 - 2 = (24 - 2) = 22
22×2 + 2 = (44 + 2) = 46

51. (a) According to question,
((sinθ - 2sin²θ)/(2cos³θ - cosθ))² + 1
= sin²θ(1 - 2sin²θ)² / cos²θ(2cos²θ - 1)² + 1
= tan²θ(cos2θ)² / (cos2θ)² + 1
= tan²θ + 1 = sec²θ
52. (c) Let Raju's expenditure = Rs. 100
Then, his income = Rs. 120
Saving = Rs. 20
Now,
New income = 120 × 160/100 = Rs.192
New expenditure = Rs. 170
New saving = 192 - 170 = Rs. 22
% increase in saving = (22 - 20)/20 × 100 = 10%
53. (b) Ratio of efficiencies, A : B : C = 4 : 5 : 3
(A + B + C) : (A + C) = 12 : 7
Now,
M₁ × D₁ / W₁ = M₂ × D₂ / W₂
12 × 25 / 1 = 7 × D₂ / 35/100
D₂ = 12 × 25 × 35/100 / 7 = 15
So, option (b) is correct answer.
54. (c) CP of another item
= 1240 × 75/100 = Rs. 930
New selling price of item
= 930 × 140/100 = Rs. 1302
Profit % = (1302 - 1240)/1240 × 100 = 620/124 = 5%
So, option (b) is correct.
55. (c) According to question,
Total production of A type cars in year 2015 and C type cars in 2013 = 48 + 52 = 100
Total production of D type cars in five years = 50 + 42 + 45 + 46 + 47 = 230
Required percent
= 100/230 × 100 = 1000/23 ≈ 43.5%
56. (a) Total production of C and E type cars in the year 2013 = 52 + 36 = 88
Total production of D in 2014 and 2016 and E in 2017 = 42 + 46 + 55 = 143
Required ratio = 88:143 = 8:13
So, option (a) is correct.
57. (d) According to question,
AB = x cm and PQ = 12 cm. AB always bisects PQ. Therefore PC = CQ = 6
AC = √(10² - 6²) = √(100 - 36) = 8
BC = √(8² - 6²) = √(64 - 36) = √28 = 5.29
x = AB = AC + BC = 8 + 5.29 = 13.29 ≈ 13.3 cm
58. (b) According to question,
Cost price of item = 288 × 100/96 = 300
Marked price = Rs. 315
Required percent = (315 - 300)/300 × 100 = 5%
59. (b) Let A's speed = a km/h, B's speed = b km/h, then
15(1/a - 1/b) = 30/60
1/a - 1/b = 1/30 ...(i)
15(1/b - 1/2a) = 1
1/b - 1/2a = 1/15 ...(ii)
Adding (i) and (ii), we get
1/2a = 3/30 = 1/10
a = 5
1/b = 1/a - 1/30 = 1/5 - 1/30 = 1/6
b = 6
So, speed of B is 6 km/hr
60. (d) Let x student were there in the class initially. Then sum of the weights of x students in class = 68.5x
According to question,
68.5x + 72.2 + 70.8 + 70.3 + 66.7 = (x + 4)(68.5 + 300/1000)
68.5x + 280 = (x + 4) × 68.8
68.5x + 280 = 68.8x + 275.2
0.3x = 4.8
x = 16
So, total number of students in the class = 16
61. (c) According to question,
16x² + 9y² + 4z² = 24(x - y + z) - 61
16x² - 24x + 9 + 9y² + 24y + 16 + 4z² - 24z + 36
= 9 + 16 + 36 - 61
(4x - 3)² + (3y + 4)² + (2z - 6)² = 0
if 4x - 3 = 0 ⇒ x = 3/4
3y + 4 = 0 ⇒ y = -4/3
2z - 6 = 0 ⇒ z = 3
xy + 2z = 3/4 × -4/3 + 2×3 = -1 + 6 = 5
62. (d) According to question,
23 - x / 39 - x = 32 - x / 56 - x
23 × 56 - 79x + x² = 39 × 32 - 71x + x²
8x = 23 × 56 - 39 × 32
x = 23 × 7 - 39 × 4
x = 161 - 156 = 5
Mean proportion
= √((x+4)(3x+1)) = √(9×16) = 12
63. (d) According to question,
[8(x + y)³ - 27(x - y)³] = (5y - x) = Ax² + Bxy + Cy²
2(x+y) - 3(x-y)[4(x+y)² + 6(x+y)(x-y) + 9(x-y)²] / 5y-x = Ax² + Bxy + Cy²
(5y - x)[4x² + 8xy + 4y² + 6x² - 6y² + 9x² - 18xy + 9y²] / 5y-x = Ax² + Bxy + Cy²
19x² - 10xy + 7y² = Ax² + Bxy + Cy²
A = 19, B = -10, C = 7
A + B + C = 19 - 10 + 7 = 16
64. (d) According to question,
∠BAC = 180° - (80° + 64°) = 180° - 144° = 36°
Since the Circle is inscribed within a triangle, AK passing through the center must be angle bisector of ∠A Therefore,
∠BAK = ∠CAK = 1/2 × 36° = 18°
Now, ∠BAD = ∠ADC - ∠ABD = 90° - 80° = 10°
Therefore,
∠DAK = ∠BAK - ∠BAD = 18° - 10° = 8°
65. (b) According to question,
∆AEF ~ ∆BDF (by AA similarity)
∠DBF = ∠EAF
Again,
∠DBF = ∠EAF
∠BDF = ∠ADC
∆BDF ~ ∆ADC (by AA similarity)
BD/AD = DF/DC = BF/AC
Given, BF = AC
BD = AD
DF = DC
∠ABD = ∠BAD = 45°
66. (d) Let the altitude of ∆DEF corresponding to ∆ABC be x
Now, we know
Ratio of Areas = (ratio of corresponding sides)²
100/49 = 5²/x²
x = 5 × 7/10 = 3.5
So, option (d) is correct.
67. (b) According to question,
Total production of B type of cars in 2013, 2014, 2015 and 2017
= 39 + 45 + 54 + 72 = 210
Total production of all types of cars in 2017
= 36 + 72 + 45 + 47 + 55 = 255
Required percent
= (255 - 210)/255 × 100 = 17.64
68. (d) Required angle
= 60/270 × 360° = 80°
69. (d) According to question, cos²θ = 3(cot²θ - cos²θ)
4cos²θ = 3cos²θ/sin²θ
cos²θ = (4sin²θ - 3) = 0
sinθ = √3/2 ⇒ θ = 60°
(1/2 secθ + sinθ)⁻¹ = (1/2 sec60° + sin60°)⁻¹
= (1/2 × 2 + √3/2)⁻¹ = 2/(2 + √3)
= 2(2 - √3)
70. (d) According to question,
cosθ = 2p/(1 + p²)
sin²θ = 1 - 4p²/(1 + p² + 2p²)
sin²θ = (1 + p⁴ + 2p² - 4p²)/(1 + p⁴ + 2p²)
sinθ = √((1 - p²)²/(1 + p²)²) = (1 - p²)/(1 + p²)
tanθ = sinθ/cosθ = (1 - p²)/(1 + p²) × (1 + p²)/2p = (1 - p²)/2p
71. (d) 5 ÷ 5 of 5 × 2 + 2 ÷ 2 of 2 × 5 - (5 - 2) ÷ 6 × 2
= 5 ÷ (5 × 5) × 2 + 2 ÷ (2 × 2) × 5 - (5 - 2) ÷ 6 × 2
= 5/25 × 2 + 2/4 × 5 - 3/6 × 2 = 2/5 + 5/2 - 1
= (4 + 25 - 10)/10 = 19/10
72. (b) Since the given number is divisible by 72, it must be divisible by 4, 8 and 9. Since, it is divisible by 4, last two digit must be divisible by 4. So, possible values of y are 2, 6. Since the number is divisible by 8 also, last three digits must be divisible by 8. Since 312 is divisible by 8, only possible value of y is 2. Now, the number is divisible by 9, therefore sum of the digit must be divisible by 9.
7 + 8 + 9 + x + 5 + 3 + 1 + y
= 33 + x + 2
= 35 + x for x = 1, this sum is divisible by 9.
5x - 3y = 5 × 1 - 3 × 2 = 5 - 6 = -1
73. (b) Amount in two year for the sum P
A = P(1 + 10/100)² A = P × 121/100
CI in two years
= A - P = 121/100 P - P = 21/100 P
Now, simple interest for 1/2 year at 10%
P × 121/100 × 10 × 1/2 = 121/2000 P
AQ,
21/100 P + 121/2000 P = 1623
(420 + 121)/2000 P = 1623
541/2000 P = 1623
P = 1623/541 × 2000
P = 3 × 2000
P = 6000
74. (c) x³ + y³ + z³ - 3xyz = (x + y + z)(x² + y² + z² - xy - yz - zx)
= 19[(x + y + z)² - 2(xy + yz + zx) - (xy + yz + zx)]
= 19[(x + y + z)² - 3(xy + yz + zx)]
= 19[19² - 3 × 114]
= 19[361 - 342] = 19 × 19 = 361
√361 = 19
75. (a) Total surface area of cuboidal tank = 2(lb + bh + hl)
= 2(10×8 + 8×6 + 6×10) = 2(80 + 48 + 60) = 2 × 188 = 376 m²
Area of circular hole = πr² = 22/7 × (0.5)² = 22/7 × 0.25 = 0.785 m²
Iron sheet needed = 376 - 0.785 = 375.215 ≈ 370.4? Wait, calculation: 376 - 0.785 = 375.215, but options show 370.4. Actually question likely asks for tank without top? Let's check: "with a circular hole of one-meter diameter on top, how much of iron sheets (m2) will be needed to make such a tank?" So open top? If open top, surface area = 2h(l+b) + lb = 2×6(10+8) + 10×8 = 12×18 + 80 = 216 + 80 = 296. Then minus hole 0.785 = 295.215, not options. So likely total surface area including top, minus hole. But options 370.4. Let's compute: 2(lb+bh+hl) = 2(80+48+60)=376. Hole area = π(0.5)²=0.785. 376-0.785=375.215. None. Maybe they considered hole on top so top area not needed? Then 376 - 80 (top) - 0.785 = 295.215. Not options. Maybe they ask "how much iron sheets needed" for closed tank with hole? Actually if hole on top, top sheet has hole, so area = total surface - hole = 375.215. Options: (a) 370.4 (b) 371.6 (c) 375.2 (d) 370.8. 375.2 is close. So answer (c) 375.2? But explanation in file says (a)? Wait file explanation not present for 75? It shows only up to 74. Then page 9 starts with 82. So missing. I'll use (c) 375.2.
