1 pointsCategory: Quantitative AptitudeThe difference between downstream speed and upstream speed of the boat is 8 km/hr and boat travels 48 km from P to Q (upstream) in 6 hours. Then find the speed of the boat in still water?
Correct
Answer: 3) 12km/hr
Explanation:
Let the speed of boat in still water be x km/hr
And that of stream be y km/hr
ATQ,
(x+y)(xy) = 8
2y = 8
y = 4 km/hr
Upstream speed(xy) = 48/6
(xy) = 8
x4 = 8
x = 12 km/hrIncorrect
Answer: 3) 12km/hr
Explanation:
Let the speed of boat in still water be x km/hr
And that of stream be y km/hr
ATQ,
(x+y)(xy) = 8
2y = 8
y = 4 km/hr
Upstream speed(xy) = 48/6
(xy) = 8
x4 = 8
x = 12 km/hr 
Question 2 of 10
2. Question
1 pointsCategory: Quantitative AptitudeIn a vessel, there are two types of liquids A and B in the ratio of 4: 3. 21 litres of the mixture is taken out and 8 litres of type A liquid is poured into it, the new ratio (A: B) thus formed is 3:2. Find the final quantity of mixture in the vessel?
Correct
Answer: 3) 120 litres
Explanation:
Let the initial quantity of mixture in the vessel be x litres
ATQ,
(x*4/7 – 12+8)/(x*3/7 – 9) = 3/2
(4x – 28)/(3x – 63) = 3/2
8x56 = 9x – 189
x = 133
Final quantity = 13321+8
Final quantity = 120 litresIncorrect
Answer: 3) 120 litres
Explanation:
Let the initial quantity of mixture in the vessel be x litres
ATQ,
(x*4/7 – 12+8)/(x*3/7 – 9) = 3/2
(4x – 28)/(3x – 63) = 3/2
8x56 = 9x – 189
x = 133
Final quantity = 13321+8
Final quantity = 120 litres

Question 4 of 10
4. Question
1 pointsCategory: Quantitative AptitudeA person has purchased two adjacent plots, one is rectangular and other is square and combined them to make a single new plot. The breadth of the rectangular plot is equal to the side of the square plot and the cost of ploughing the new plot is Rs. 576 (Rs. 8/m2). Find the side of the square if the length of the rectangular plot is 14 m.
Correct
Answer: 4) 4m
Explanation:
Let the breadth of rectangular plot be x m and length = 14 m
ATQ,
Area of new plot
x*(14+x) = 576/8
x*(14+x) = 72m2
x2+14x72 = 0
x2+18x4x72 = 0
x(x+18)4(x+18) = 0
(x4)*(x+18) = 0
x = 18, 4 (but side of square cannot be –ve)
Therefore, side of square = 4mIncorrect
Answer: 4) 4m
Explanation:
Let the breadth of rectangular plot be x m and length = 14 m
ATQ,
Area of new plot
x*(14+x) = 576/8
x*(14+x) = 72m2
x2+14x72 = 0
x2+18x4x72 = 0
x(x+18)4(x+18) = 0
(x4)*(x+18) = 0
x = 18, 4 (but side of square cannot be –ve)
Therefore, side of square = 4m 
Question 5 of 10
5. Question
1 pointsCategory: Quantitative AptitudeA shopkeeper marked his article 40% above the cost price and gives a discount of 10% on it. If he had marked his article 55% above the cost price and gives a discount of 15% on it then find the earlier profit is approximately what percent of the profit earned latter?
Correct
Answer: 2) 82%
Explanation:
Let the CP be Rs. 100x
Then, MP = Rs. 140x
SP = 140x*(90/100) = 126x
Profit = 126x100x = 26x
New MP = Rs. 155x
New SP = 155x*(85/100) = 131.75x
Profit = 131.75x100x = 31.75x
Required % = (26x/31.75x)*100 = 81.88% = 82% (approx)Incorrect
Answer: 2) 82%
Explanation:
Let the CP be Rs. 100x
Then, MP = Rs. 140x
SP = 140x*(90/100) = 126x
Profit = 126x100x = 26x
New MP = Rs. 155x
New SP = 155x*(85/100) = 131.75x
Profit = 131.75x100x = 31.75x
Required % = (26x/31.75x)*100 = 81.88% = 82% (approx)
