Quantitative Aptitude Mock Test-2: Answers with Solutions
1. Answer (a)
Explanation: Required number of sweets in each box = LCM (20, 25,38 and 40) – 5
⇒ 3,800 − 5 = 3,795.
2. Answer (c)
3. Answer (a)
Explanation: The customer pays Rs. 63 after a discount of 10%.
If the list price is Rs. x , then
X – 10% of x = 63
X = Rs. 70
Therefore, the list price = Rs. 70
The retailer buys the article at 30 % discount
= 70 – 30 % of 70
= Rs. 49
Then the profit for the retailer = Rs. (63 - 49) = Rs.14.
4. Answer (c)
Explanation: Amount returned on the completion of course = 12,00,000 × (1.08)2 = 13,99,680
Half returned after completion of two years = 6,99,840
Amount returned after two year of completion of course = 6,99,840 × (1.10)2 = 8,46,806
Total amount returned = 6,99,840 + 8,46,806 = 15,46,646
5. Answer (b)
6. Answer (a)
7. Answer (b)
Explanation: Let the total time that Ram takes to complete the entire journey be t hours
Ram spent 40%, 50% and the remaining 10% of the time walking, in the bus and in the cab respectively.
Thus, time spent walking, in the bus and in the cab are 0.4 t, 0.5 t and 0.1 t respectively.
So Average speed=Total distance covered/ Total Time taken
= 40(0.4 t) + 60(0.5 t) + 150(0.1 t)/t = 61 km/hr
8. Answer (d)
Explanation: Distance = (45/60)×120 = (x/60) ×108.
∴ x= 50 minutes.
9. Answer (d)
Explanation: Since first work for 4 days and second work for 6 days, the work left (which is given as 1/5 of the total work) would be the work the first person to do would be 10 days. His rate of work would be 10% per day. According to question, Let the number of days required by slower person be X.
10. Answer (c)
Explanation: Total rise in height= 8 X 4 cm = 32 cm
The height of the new person= 160+32 cm = 192 cm.
11. Answer (c)
Explanation: Let the ages of Rahul and sumit be 3x and 7x respectively.
According to question,
Difference in their ages = 7x – 3x = 4x = 20 years.
12. Answer (c)
Explanation: Let the students in the class be 2x, 4x and 5x.
2x + 40 + 4x + 40 + 5x + 40 = 4x + 7x + 8x
11x + 120 = 19x
x = 15
The number of students= 30 + 60 + 75 = 165
13. Answer (b)
14. Answer (a)
15. Answer (a)
16. Answer (c)
17. Answer (c)
Explanation: As it is a regular star, all the edges will be equal. Also, the angle of vertex is 60ᵒ which means all the flanges of stars will be equilateral triangle.
Now, let n be the number of flanges of the star.
Keeping in mind the above statements,
(Angle of vertex) X (number of flanges) = 360ᵒ
60 X n = 360
n = 6
Let length of one edge be l. As each flange has 2 edges and the star is made of 48 cm wire.
n × 2l = 48 6 × 2l = 48
l = 4 cm
18. Answer (b)
19. Answer (c)
20. Answer (a)
4sin2 θ + 5cos2 θ
4sin2 θ + 4cos2 θ + cos2 θ
4(sin2 θ + cos2 θ) + cos2 θ
4 + cos2 θ
Minimum value of cosθ = -1
Required minimum value = 4+1 =5
21. Answer (d)
Explanation: Total selling and distribution cost =82500
Selling and distribution constitute = 15%
Therefore total cost = 82500/15 × 100 = 550000
To earn 25% profit = 550000/55 × 125 = 12,500
22. Answer (d)
Explanation: Central angle of 18º = (18/360 x 100) = 5%
The difference between two costs should be 5%.
From the given chart it is clear that, Out of the given combinations, only in combination (d) is true.
23. Answer (c)
Explanation: Selling and distribution = Rs. 56250 and constitutes 15%.
Total cost of Raw material and labour = 56250/15 × 35 = 1,31,250
24. Answer (b)
Explanation: Central angle of 1080 = (108/360 x 100) = 30% of the total expenditure
= 30% of the total costs.
25. Answer (d)
Explanation: C.P. of machine = 14,400/120 × 100 = 12,000
Advertising cost of a single machine = 12,000 × 10/100 = 1200
