Following is the Quantitative Aptitude quiz to help you practice with the best of latest pattern questions

Directions (1-3): In the given questions, two quantities are given, one as ‘Quantity I’ and another as ‘Quantity II’. You have to determine relationship between two quantities and choose the appropriate option:

Q1. 5X men can complete a work in X/2 days while 2Y men can complete same work in 4Y/5 days.
Quantity I: Value of ‘Y+20’.
Quantity II: Value of ‘1.25X'

Quantity I ≥ Quantity II

Quantity I = Quantity II or No relation

Quantity I > Quantity II

Quantity I < Quantity II

Quantity I ≤ Quantity II

Solution:

Q2. Rs. X is invested in a scheme which offers 15% p.a. at C.I. Interest earned after two years is Rs.3870.
Quantity I: ‘Value of ‘A’. Rs. 2X is invested in a scheme which offers A% p.a. at C.I. and interest earned after two years is Rs. 10,560
Quantity II: Value of ‘B’. Rs. (X+6,000) is invested in a scheme which offers B% p.a. at C.I. and amounts to Rs. 28,125 after two years.

Quantity I > Quantity II

Quantity I = Quantity II or No relation

Quantity I ≥ Quantity II

Quantity I < Quantity II

Quantity I ≤ Quantity II

Solution:

Q3. Total surface area of a cylinder is 200% more than that of its sum of area of base and top of cylinder. Volume of cylinder is 2156 cm³
Quantity I: Volume of cone, whose base radius and height is same as that of radius and height of cylinder respectively.
Quantity II: Volume of hemisphere, whose radius is same as that of radius of cylinder.

Quantity I > Quantity II

Quantity I = Quantity II or No relation

Quantity I ≥ Quantity II

Quantity I < Quantity II

Quantity I ≤ Quantity II

Solution:

Directions (4-5): in the following questions two statements (Quantity -I and quantity -II) are given. You have to solve both the statements and give answer. (Note: Consider only numerical value while comparing)

Q4. Quantity – I. The marked price (in Rs) of a watch, which is marked as 40% above of its cost price and 20% profit is earned by selling it at Rs 216.
Quantity – II. 252

If quantity I > Quantity II

If quantity I < Quantity II

If quantity I ≥ Quantity II

If quantity I ≤ Quantity II

if quantity I = Quantity II or no relation between quantity I and II.

Solution:

Q5. Quantity - I. Length of the train P (in meter), which crosses another train Q coming towards it at a speed of 72 km/h in 40sec. Ratio of length of train P and Q is 3 : 2 and speed of train P is 25% more than that of Q
Quantity – II. Value of x, x² - 353 = 376

If quantity I > Quantity II

If quantity I < Quantity II

If quantity I ≥ Quantity II

If quantity I ≤ Quantity II

if quantity I = Quantity II or no relation between quantity I and II.

Solution:

Directions (6-10): Each of the questions consists of a question followed by three statements. You have to study the questions and the statements and decide which of the statements(s) is/are necessary to answer the question.

Q6. What is the area of the hall?
I. Material cost of flooring per sq metre is Rs. 250
II. labour cost of flooring the hall is Rs. 3,500
III. Total cost of flooring the hall is Rs. 14,500

I and II only

II and III only

All I, II and III

Any two of the three

None of these

Solution:

Let area = x m²
Then,
250x + 3500 = 14500
By this equation, we can find x
So, all the three statements are required

Q7. What was the percentage of discount offered?
I. Profit earned by selling the article for Rs. 252 after giving discount was Rs. 52.
II. Had there been no discount the profit earned would have been Rs. 80
III. Had there been no discount the profit earned would have been 40%.

I and II only

II and either I or III only

I and III only

I and either II or III only

None of these

Solution:

I. S.P. = 252
Profit = 52
C.P. = 252 – 52 = 200
II. Profit = 80 (when no discount)
So, M.P =200+80=280
III. When discount = 0
Profit = 40%

So, we can calculate M.P. and consequently discount percentage.
So, statement I with either II or III is necessary to answer the question

Q8. What is the speed of the train?
I. The train crosses a signal pole in 13 sec.
II. The train crosses a platform of length 250 m in 27 seconds.
III. The train crosses another train running in the same direction in 32 seconds.

I and II only

I and III only

II and III only

Any two of the three

None of these

Solution:

I. Time to cross a pole =13 sec

So, from above equations, we can see statement I & II are sufficient to find out speed of train.

Q9. What is the population of State ‘A’?
I. After increasing the population of State A by 15% it becomes 1.61 lakhs
II. Ratio of population of State A to that of State B is 7 : 8 respectively
III. Population of State B is 1.6 lakhs

I only

II and III only

I and II only

Either only I or II and III together

All I, II and III

Solution:

II. A∶B=7∶8
III. B=1.6 lakh
So, we can see, population of A can be find out either only by statement I or statement II & III together.

Q10. How many workers are required for completing the construction work in 10 days?
I. 20% of the work can be completed by 8 workers in 8 days
II. 20 workers can complete the work in 16 days
III. One eighth of the work can be completed by 8 workers in 5 days

I and II only

II and III only

I only

III only

Any one of three

Solution:

I. n × 10 = 8 × 8 × 5
II. n × 10 = 20 × 16
III. n × 10 = 8 × 5 × 8
So, from any of the three statements, we can get the answer.

Directions (11- 15): Find out the missing no. in the given series.

Q11. 2, 7, 24, 61, ?, 227

116

126

129

136

125

Solution:

Pattern of the difference between the numbers is +2² + 1, + 4² + 1, + 6² + 1, + 8² + 1, and so on
Hence, ? = 126

Q12. 76, 151, 454, 1815, ?

9070

9072

9054

9074

9076

Solution:

Pattern is ×2 - 1 , ×3 + 1, ×4 - 1,so on
∴ ? = 1815 × 5 + 1 = 9076

Q13. 2, 4, 12, 48, 240, ?

960

1440

1080

1920

1960

Solution:

Go on multiplying the given numbers by 2, 3, 4, 5, 6. So, the correct next number is 1440.

Q14. 7, 26, 63, 124, 215, 342, ?

481

511

391

421

841

Solution:

Number are (2³ – 1), (3³ – 1), (4³ – 1), (5³ – 1), (6³ – 1), (7³ – 1) etc.
So, the next number is (83 – 1) = (512 – 1) = 511.

Q15. 8, 24, 12, 36, 18, 54, ?

108

Solution:

Numbers are alternately multiplied by 3 and divided by 2.
So, the next number = 54 ÷ 2 = 27.
