Section 3: Quadratic Equation Questions (11–15)

Directions: In each question, two equations (I) and (II) are given. Solve both equations and establish the relationship between x and y.

Use the following options:

• (A) x > y
• (B) x < y
• (C) x ≥ y
• (D) x ≤ y
• (E) Relationship cannot be established

Q11.

I. x² − 11x + 30 = 0

II. y² − 13y + 42 = 0

Answer: (D) x ≤ y

Solution:

Equation I:

x² − 11x + 30 = 0

(x − 5)(x − 6) = 0

x = 5, 6

Equation II:

y² − 13y + 42 = 0

(y − 6)(y − 7) = 0

y = 6, 7

Both possible values of x are less than or equal to the corresponding minimum value of y.

Therefore, x ≤ y.

Q12.

I. 2x² + 7x + 6 = 0

II. y² + 5y + 6 = 0

Answer: (C) x ≥ y

Solution:

Equation I:

(2x + 3)(x + 2) = 0

x = −3/2, −2

Equation II:

(y + 2)(y + 3) = 0

y = −2, −3

The smallest value of x is −2, and the greatest value of y is −2.

Therefore, x ≥ y.

Q13.

I. x² = 64

II. y = 64

Answer: (B) x < y

Solution:

From equation I:

x² = 64

x = ±8

From equation II:

y = 64

Both possible values of x (−8 and 8) are less than 64.

Therefore, x < y.

Q14.

I. x² − 5x − 24 = 0

II. y² − 7y − 18 = 0

Answer: (B) x < y

Solution:

Equation I:

(x − 8)(x + 3) = 0

x = 8, −3

Equation II:

(y − 9)(y + 2) = 0

y = 9, −2

Both possible values of x are less than the corresponding values of y.

Therefore, x < y.

Q15.

I. 3x² − 10x + 8 = 0

II. 2y² − 7y + 6 = 0

Answer: (E) Relationship cannot be established

Solution:

Equation I:

3x² − 10x + 8 = 0

(3x − 4)(x − 2) = 0

x = 4/3, 2

Equation II:

2y² − 7y + 6 = 0

(2y − 3)(y − 2) = 0

y = 3/2, 2

The possible values overlap, and neither variable is consistently greater than or equal to the other.

Therefore, the relationship cannot be established.

Section 4: Data Interpretation Questions (16–30)

Data Interpretation is an important part of the IBPS RRB PO Quantitative Aptitude section. The following three sets cover table-based DI, bar graph DI and caselet DI, testing calculations involving averages, percentages, ratios and differences.

• 30 students like Football and Hockey but not Cricket.
• The remaining students like Cricket and Hockey but not Football.

Q26. How many students like both Cricket and Hockey but not Football?

Answer: 50

Solution:

Only Cricket = 20% of 400 = 80

Only Football = 15% of 400 = 60

Only Hockey = 25% of 400 = 100

All three sports = 10% of 400 = 40

Students liking both Cricket and Hockey:

= 400 − (80 + 60 + 100 + 40 + 40 + 30)

= 50

Q27. What is the total number of students who like Cricket?

Answer: 210

Solution:

Total students who like Cricket:

= Only Cricket + Cricket and Football + Cricket and Hockey + All three

= 80 + 40 + 50 + 40

= 210

Q28. Find the ratio of students who like only Football to those who like only Hockey.

Answer: 3:5

Solution:

Only Football = 60

= 120

Required percentage:

= (120 ÷ 400) × 100

= 30%

Q30. How many students do not like Football?

Answer: 230

Solution:

Students who do not like Football:

= Only Cricket + Only Hockey + Cricket and Hockey but not Football

= 80 + 100 + 50

= 230

Section 5: Arithmetic Questions (31–40)

Arithmetic questions test candidates’ understanding of basic mathematical concepts and their ability to solve word problems quickly. The following questions cover important topics such as Ages, Partnership, Profit and Loss, Interest, Time and Work, Speed and Distance, Mixture and Alligation, Mensuration and Probability.

Q31. Ages

The ratio of the current ages of A and B is 4:5. After 5 years, the ratio of their ages will become 5:6. Find the present age of A.

Answer: 20 years

Solution:

Let the present ages of A and B be 4x and 5x.

According to the question:

(4x + 5) / (5x + 5) = 5/6

6(4x + 5) = 5(5x + 5)

24x + 30 = 25x + 25

x = 5

Present age of A = 4 × 5

= 20 years

Q32. Partnership

A and B start a business by investing ₹12,000 and ₹16,000, respectively. After 8 months, C joins them with an investment of ₹20,000. If the total annual profit is ₹46,000, find C’s share of the profit.

Answer: ₹8,846.15 (approximately)

Solution:

Profit-sharing ratio:

A = 12,000 × 12 = 1,44,000

B = 16,000 × 12 = 1,92,000

C = 20,000 × 4 = 80,000

Ratio = 144:192:80

= 9:12:5

Total parts = 9 + 12 + 5 = 26

C’s share:

= (5 ÷ 26) × 46,000

= ₹8,846.15 approximately

Q33. Profit and Loss

A shopkeeper marks up his goods by 40% above the cost price and then allows a discount of 20% on the marked price. Find his overall profit or loss percentage.

Answer: 12% profit

Solution:

Let the cost price = ₹100

Marked price = 100 + 40 = ₹140

Selling price = 140 − 20% of 140

= 140 − 28 = ₹112

Profit = 112 − 100 = ₹12

Profit percentage = 12%

Q34. Simple and Compound Interest

A sum of ₹8,000 is invested at 10% per annum compound interest, compounded annually for 2 years. Find the total interest earned.

Answer: ₹1,680

Solution:

Principal = ₹8,000

Rate = 10%

Time = 2 years

Amount = 8,000 × (1 + 10/100)²

= 8,000 × 1.21

= ₹9,680

Compound Interest = 9,680 − 8,000

= ₹1,680

Q35. Time and Work

A can complete a piece of work in 12 days, and B can complete the same work in 18 days. If they work together for 4 days, what fraction of the work is left?

Answer: 4/9

Solution:

A’s one-day work = 1/12

B’s one-day work = 1/18

Combined one-day work:

= 1/12 + 1/18

= 5/36

Work completed in 4 days:

= 5/36 × 4

= 20/36 = 5/9

Remaining work:

= 1 − 5/9

= 4/9

Q36. Time, Speed and Distance

A train running at a speed of 72 km/h crosses a pole in 15 seconds. Find the length of the train in metres.

Answer: 300 metres

Solution:

Speed = 72 × 5/18

= 20 m/s

Length of train = Speed × Time

= 20 × 15

= 300 metres

Q37. Boats and Streams

A boat can travel at a speed of 12 km/h in still water. If the speed of the stream is 3 km/h, find the time taken by the boat to travel 45 km downstream.

Answer: 3 hours

Solution:

Downstream speed = Speed in still water + Stream speed

= 12 + 3 = 15 km/h

Time = Distance ÷ Speed

= 45 ÷ 15

= 3 hours

Q38. Mixture and Alligation

A 60-litre mixture contains milk and water in the ratio 7:3. How many litres of water must be added to make the ratio of milk to water 1:1?

Answer: 24 litres

Solution:

Total mixture = 60 litres

Milk = 60 × 7/10 = 42 litres

Water = 60 × 3/10 = 18 litres

For a 1:1 ratio, water must equal milk.

Additional water required:

= 42 − 18

= 24 litres

Q39. Mensuration

The length of a rectangle is 4 cm more than its breadth. If the perimeter of the rectangle is 48 cm, find its area.

Answer: 140 cm²

Solution:

Let breadth = x cm

Length = (x + 4) cm

Perimeter = 2 × (Length + Breadth)

48 = 2(x + 4 + x)

24 = 2x + 4

2x = 20

x = 10 cm

Breadth = 10 cm

Length = 14 cm

Area = Length × Breadth

= 14 × 10

= 140 cm²

Q40. Permutation and Probability

A bag contains 4 red, 5 blue and 3 green balls. If two balls are drawn at random, what is the probability that both balls are blue?

Answer: 5/33

Solution:

Total balls = 4 + 5 + 3 = 12

Blue balls = 5

Probability of drawing the first blue ball = 5/12

Probability of drawing the second blue ball = 4/11

Required probability:

= (5/12) × (4/11)

= 20/132

= 5/33
