A. 100 Km B. 120 Km C. 140 km D. 160 km

Answers and Explanations
1. Answer - Option B
Explanation -
Let the total work be 8 × 3 = 24 units.
[latex]\Rightarrow[/latex] Work done by C in 1 day = 3 units and that by B = 1 unit.
Thus, time taken by B and C together = 6 days while that by A alone = 8 days.
[latex]\Rightarrow[/latex] Work done by A in 1 day = 3 units
Hence, required time = [latex]\frac{24}{4}[/latex] = 6 days.
2. Answer - Option A
Explanation -


[latex]{AB}^{2} = {AO}^{2} + {OB}^{2}[/latex]
[latex]\Rightarrow {29}^{2} = {20}^{2} + {OB}^{2}[/latex]
[latex]\Rightarrow OB = 21 cm[/latex]
Hence, required area
[latex]= 4 * \frac{1}{2} * 21 * 20 = 840{cm}^{2}[/latex]
3. Answer - Option D
Explanation -
[latex]= x * \frac{17}{20} * \frac{7}{8} * \frac{4}{5} = * \frac{119}{200} =[/latex] 59.5% of x
Hence, required discount = 40.5%.
4. Answer - Option B
Explanation -
25% of A = 35% of B
[latex]\Rightarrow[/latex] A : B = 7 : 5
Hence, required amount = [latex]\frac{7}{12}[/latex] × 2448
= Rs. 1,428
5. Answer - Option C
Explanation -
Let the selling price of 1 article be Re.1
[latex]\Rightarrow[/latex] Cost price of 50 articles = Rs. 40 and their
selling price = Rs. 50
Hence, there would be profit equivalent to
[latex]\frac {50 – 40}{40}[/latex] × 100 = 25%
6. Answer - Option B
Explanation -
Let the income of B = Rs. 100
[latex]\Rightarrow[/latex] A's income = Rs. 125 and C's income = Rs. 120
Hence, required percentage
= [latex]\frac {125 – 120}{120}[/latex] × 100 = 4.16%
7. Answer - Option B
Explanation -
Relative speed = 45 + 4.5 = 49.5 km/hr
= 49.5 × [latex]\frac{5}{18}[/latex] = 13.75 m/s
Hence, required time = [latex]\frac{143}{13.75}[/latex] = 10.4 seconds.
8. Answer - Option C
Explanation -
Going through the options we get the required answer as 12 : 5.
9. Answer - Option
Explanation -
[latex]({cos}^{2} A - sin A)(sin A + {cos}^{2} A)[/latex] = -1
[latex]\Rightarrow {cos}^{4} A - {sin}^{2} A[/latex] = -1
[latex]\Rightarrow {cos}^{4} A + {cos}^{2} A[/latex] = 0
[latex]\Rightarrow {cos}^{2} A({cos}^{2} A + 1)[/latex] = 0
Since [latex]{cos}^{2} A [/latex] can never be negative in the given range thus A = 90° and [latex]({cos}^{2} A + 2)[/latex] = 2
10. Answer - Option B
Explanation -
Let the fifth angle be x°.
Sum of all the exterior angles of any polygon is always 360°.
[latex]\Rightarrow
[/latex] (180 – 140)° + (180 – 90)° + (180 – 70)° + (180 – 80)° + (180 – x)° = 360°
Hence, x = 160°.
11. Answer - Option C
Explanation -
[latex]secA(secA + tanA + \frac{cos A}{1 + sinA}) - 2{tan}^{2} A[/latex], we get the required value as 2.

Explanation -
[latex]\frac{2 * {8}^{n + 1} + 4 * {2}^{3n - 1} }{4 * {2}^{2n + 1} - 2 * {4}^{3n + 1} } [/latex]
= [latex]\frac{{2}^{3n + 4} + 2 * {2}^{3n + 1} }{{2}^{2n + 3} - {2}^{4n + 3} } [/latex]
= [latex]\frac{{2}^{10} + 2 * {2}^{7} }{{2}^{7} - {2}^{11} } = - \frac {3}{5}[/latex]
13. Answer - Option B
Explanation -
Age of the teacher = 17 × 22 – 16 × 18.5
= 78 years.
14. Answer - Option A
Explanation -
b + [latex]\frac{1}{b} = -1[/latex]
[latex]\Rightarrow {b}^{2} + b + 1[/latex]
[latex]\Rightarrow (b - 1)({b}^{2} + b + 1) = 0[/latex]
[latex]\Rightarrow {b}^{3} = 1[/latex]
[latex]{b}^{9} + \frac{1}{{b}^{15}} = 2[/latex]
15. Answer - Option
Explanation -

17. Answer - Option B
Explanation -
14600 * [latex]{(1 + \frac{r}{100})}^{2}[/latex] = 16,404.56
[latex]\Rightarrow [/latex]r = 6 %
18. Answer - Option C
Explanation -

In △ABE ,
AB tan 30º = [latex]\frac{AB}{40 \sqrt{3}}\Rightarrow AB = 40 m[/latex]
In △EDC,
sin 45º [latex]\frac{40}{EC}\Rightarrow EC = 40 \sqrt{2} m[/latex]
19. Answer - Option B
Explanation -
[latex](33000(1 +\frac{20}{100 ) - x (1 + \frac{20}{100})} = x[/latex]
[latex]\Rightarrow \frac{x * 5}{6} + x = 33000 * \frac{6}{5}[/latex]
[latex]\Rightarrow x * \frac{11}{6} = 39600[/latex]
[latex]\Rightarrow x = Rs. 21,600[/latex]
20. Answer - Option B
Explanation -
Difference between the two time limits
= 15 hrs. = 15 × 60 × 60 = 54000 sec
[latex]\Rightarrow[/latex] Lag at the end of 54000 sec
= 5400 sec = 1 hr 30 min
Hence, the time shown = 7:30 p.m.
21. Answer - Option C
Explanation -
Given x – y = 6 and [latex]{x}^{2} - {y}^{2}[/latex] = 60
therefore, x + y= 10
Hence, the average of x and y = [latex]\frac{x + y}{2} = \frac{10}{2} = 5[/latex]
22. Answer - Option A
Explanation -
x = [latex]\frac{1}{3 + \frac{3}{5 + \frac{4}{5 + \frac{7}{2}}}}[/latex]
x = [latex]\frac{1}{3 + \frac{3}{5 + \frac{4}{\frac{17}{2}}}}[/latex]
x = [latex]\frac {1}{3 + \frac{3}{\frac{93}{17}}}[/latex]
x = [latex]\frac{1}{3 + \frac{51}{93}}[/latex]
x = [latex]\frac{93 }{31} = \frac{31 }{110}[/latex]
23. Answer - Option A
Explanation -
[latex]\frac{a}{b} = \frac{1}{4} and \frac{b}{c} = \frac{2}{3}[/latex]
[latex]\Rightarrow a : b : c = 1 : 4 : 6[/latex]
[latex]\frac{12 {a}^{2} - 8 {c}^{2}}{33 {a}^{2} + {c}^{2}} = \frac{12 {1}^{2} - 8 {6}^{2}}{33 {1}^{2} + {6}^{2}}[/latex]
[latex]\frac {12 (1 - 24)}{3 (11 + 12)} = -4[/latex]
24. Answer - Option D
Explanation -

∠ABO = ∠OBP
= [latex]\frac{∠ABC}{2}[/latex]
and ∠OBP = 90º - ∠BOP
= 90º - 39º - 51º
Hence, ∠ABC = 2 * 51º = 102º.
25. Answer - Option D
Explanation -
Let the 3 digit number be 100x + 10y + z. Then,
(100z + 10y + x) – (100x + 10y + z)
= 99(z – x) = 9 × 11 × a number.
26. Answer - Option C
Explanation -
Let the capacity of the tank be (LCM of 12, 18 and 36) 36 units. Then,
Pipe A empties [latex]\frac{36}{12}[/latex] = 3 units,
pipe B empties [latex]\frac{36}{18}[/latex] = 2 units
while pipe C empties [latex]\frac{36}{36}[/latex] = 1 unit from the tank in 1 minute.
Hence, required time = [latex]\frac{36}{3 + 2 + 1}[/latex] = 6 minutes.
27. Answer - Option B
Explanation -
Let ‘r’ be the radius of the circle and ‘a’ be the length of the side of the square. Then, ‘r’ is the in radius of the equilateral triangle.
[latex]\Rightarrow r = \frac{6}{2 \sqrt{3}} = \sqrt{3} cm[/latex]
[latex]\Rightarrow [/latex] Diameter= 2r = 2 [latex] \sqrt{3} cm[/latex]
i.e, Diameter of the circle = Diagonal of the square
[latex]\Rightarrow [/latex] Diagonal of the square = 2 [latex] \sqrt{3} cm[/latex]
[latex]\Rightarrow [/latex] Side of the square = [latex] \frac{2 \sqrt{3}}{\sqrt{2}} = \sqrt{6} cm[/latex]
Hence, area of the square = [latex]{\sqrt{6}}^{2} = 6 {cm}^{2}[/latex]
28. Answer - Option C
Explanation -
Let the level of the milk in the jar be ‘h’. Then,
volume of the conical vessel = volume of the cylinder jar
