41. Answer: Option C
Explanation: Let the speed of stream be x km/hr Then, Speed of upstream = x × [latex]\frac{600}{100}[/latex] = 18 ⇒ x = 3 km/hr Speed of boat in still water = 18 + 3 = 21 km/hr Distance covered in 3 hours in downstream = (21 + 3) × 3 = 72 km
42. Answer: Option A
Explanation: (A + B)(A – B) = 252 ⇒ 42 × (A – B) = 252 [A + B = 42 given] ⇒ (A – B) = 6 … (i) And A + B = 42 … (ii) Solve (i) and (ii), we get B = 18
43. Answer: Option D
Explanation: Let the time taken by A and B be 5x days and 3x days respectively. ⇒ 5x = 40 days ⇒ x = 8 days B’s time = 3 × 8 = 24 days Time taken by both together to complete the work = [latex]\frac{(40 × 24)}{(40 + 24)}[/latex] = 15 days
44. Answer: Option B
Explanation: Speed of train =72 km/hr= 30 m/s Length of train = 18 × 20 = 360 m Length of (train + platform) = 20 × 33 = 660 m ∴ length of platform = 660 m – 360 m = 300 m
45. Answer: Option E
Explanation: radius = 66 ×[latex]\frac{7}{(2 × 22)}[/latex] = [latex]\frac{21}{2}[/latex] Side of square =[latex]\frac{21}{4}[/latex] Area of square= ([latex]{\frac{21}{4}}^{2}[/latex]) = [latex]\frac{441}{16}[/latex] = 28 sq. cm. (approx.)
46. Answer: Option D
Explanation: Let total employees in company be 100x ATQ, ([latex]\frac{25}{100}[/latex]) × 100x = 90 ⇒ Total employees in company = 100x = 360 Employees working in HR department = ([latex]\frac{2}{9}[/latex]) × 360 = 80 Employees working in Sales department = ([latex]\frac{125}{100}[/latex])× 80 = 100 Remaining employees = 360 − 90 − 80 − 100 = 90 Employees working in Security department = ([latex]\frac{4}{9}[/latex]) × 90 = 40 Employees working in Housing department = ([latex]\frac{5}{9}[/latex])× 90 = 50

{[latex]\frac{(80 - 40)}{40}[/latex]} × 100 = 100%
47. Answer: Option C
