Aptitude Questions with Solutions

Question 1: Number Series

Find the next term: 3, 8, 15, 24, 35, ?

Solution: The series follows the pattern: n(n+2) or consecutive products

• 1×3 = 3
• 2×4 = 8
• 3×5 = 15
• 4×6 = 24
• 5×7 = 35
• 6×8 = 48

---

Question 2: Profit and Loss

By selling 45 lemons for ₹40, a man loses 20%. How many lemons should he sell for ₹24 to gain 20%?

Solution: SP of 45 lemons = ₹40 at 20% loss CP of 45 lemons = 40/0.8 = ₹50

For 20% gain on ₹24: CP = 24/1.2 = ₹20

If 45 lemons cost ₹50, then for ₹20: Lemons = (45 × 20)/50 = 18 lemons

---

Question 3: Time and Work

10 men can complete a work in 12 days. After working for 6 days, 5 more men join. In how many days will the remaining work be completed?

Solution: Total work = 10 × 12 = 120 man-days Work done in 6 days = 10 × 6 = 60 man-days Remaining work = 60 man-days

Now 15 men work: Days required = 60/15 = 4 days

---

Question 4: Percentage

A number increased by 20% gives 480. What is the number?

Solution: Let the number be x 1.20x = 480 x = 480/1.20 = 400

---

Question 5: Speed and Distance

Two trains of length 200m each are running on parallel tracks. When moving in the same direction at 40 km/hr and 50 km/hr, they will cross each other in:

Solution: Relative speed = 50 - 40 = 10 km/hr = 10 × (5/18) m/s = 25/9 m/s Total distance = 200 + 200 = 400m

Time = 400 × 9/25 = 144 seconds = 2 min 24 sec

---

Question 6: Average

The average age of 8 persons increases by 2 years when a person aged 24 years is replaced by a new person. Find the age of the new person.

Solution: Increase in total age = 8 × 2 = 16 years Age of new person = 24 + 16 = 40 years

---

Question 7: Ratio and Proportion

Divide ₹1400 among A, B, C such that A gets 2/3 of what B gets and B gets 1/4 of what C gets.

Solution: B = C/4 → C = 4B A = 2B/3

A:B:C = 2B/3 : B : 4B = 2/3 : 1 : 4 = 2:3:12

A's share = (2/17) × 1400 = ₹164.70 ≈ ₹165 B's share = (3/17) × 1400 = ₹247 C's share = (12/17) × 1400 = ₹988

---

Question 8: Simple Interest

The SI on a sum for 3 years at 8% per annum is ₹9600. Find the principal.

Solution: SI = PRT/100 9600 = P × 8 × 3/100 P = 9600 × 100/24 = ₹40,000

---

Question 9: Probability

A card is drawn from a pack of 52 cards. Find the probability of getting a king or a queen.

Solution: P(King) = 4/52 P(Queen) = 4/52 P(King or Queen) = 4/52 + 4/52 = 8/52 = 2/13

---

Question 10: Compound Interest

Find the CI on ₹5000 for 2 years at 10% per annum compounded annually.

Solution: Amount = 5000 × (1.10)² = 5000 × 1.21 = ₹6050 CI = 6050 - 5000 = ₹1050

---

Question 11: Permutation

How many 3-digit numbers can be formed using digits 1, 2, 3, 4, 5 without repetition?

Solution: Number of 3-digit numbers = ⁵P₃ = 5 × 4 × 3 = 60

---

Question 12: Clock

At what angle are the hands of a clock at 3:30?

Solution: Hour hand position = 3 × 30 + 30 × 0.5 = 90 + 15 = 105° Minute hand position = 30 × 6 = 180°

Angle = 180 - 105 = 75°

---

Question 13: Mixture

A vessel contains 60 liters of milk. 6 liters are taken out and replaced by water. This process is repeated once more. Find the quantity of milk left.

Solution: Using the formula: Final quantity = Initial × (1 - x/n)^k Where x = 6, n = 60, k = 2

Final milk = 60 × (1 - 6/60)² = 60 × (9/10)² = 60 × 81/100 = 48.6 liters

---

Question 14: Number System

Find the unit digit of 7^2024.

Solution: Pattern of unit digits for powers of 7: 7, 9, 3, 1 (cycle of 4) 2024 ÷ 4 = 506 remainder 0 When remainder is 0, unit digit is the last in cycle = 1

---

Question 15: Data Interpretation

The ratio of boys to girls in a school is 3:5. If there are 480 girls, find the total number of students.

Solution: Girls = 5 parts = 480 1 part = 96 Boys = 3 parts = 288 Total = 480 + 288 = 768
