🧮 Aptitude Questions (15 Questions with Solutions)

Question 1: Time and Work

A can do a piece of work in 10 days, B in 15 days. They work for 5 days; the rest is done by C in 2 days. If they get ₹1500 for the whole work, find the daily wages of B and C together.

Solution: A's 5 days work = 5/10 = 1/2
B's 5 days work = 5/15 = 1/3
Total by A+B = 1/2 + 1/3 = 5/6

Remaining work = 1/6 done by C in 2 days
C's 1 day work = 1/12

Ratio of work: A:B:C = 1/10 : 1/15 : 1/12 = 6:4:5

B's share = (4/15) × 1500 = ₹400 for 5 days = ₹80/day
C's share = (5/15) × 1500 = ₹500 for 2 days = ₹250/day

Daily wages of B+C = ₹80 + ₹250 = ₹330

Question 2: Profit and Loss

A trader marks his goods at such a price that after allowing a discount of 10%, he gains 15%. If the cost price is ₹400, find the marked price.

Solution: SP = 400 × 1.15 = ₹460
MP × 0.90 = 460
MP = 460/0.90 = ₹511.11

Question 3: Mixture and Alligation

In what ratio must water be mixed with milk costing ₹48 per liter to get a mixture worth ₹36 per liter?

Solution: Using alligation rule:
Water (₹0) Milk (₹48)
\ /
\ /
Mixture (₹36)

Ratio = (48-36) : (36-0) = 12 : 36 = 1:3

Question 4: Compound Interest

The compound interest on ₹10,000 in 2 years at 4% per annum, compounded half-yearly is:

Solution: Rate per half-year = 4/2 = 2%
Number of periods = 2 × 2 = 4

Amount = 10000 × (1 + 0.02)^4
= 10000 × 1.08243216
= ₹10,824.32

CI = ₹10,824.32 - ₹10,000 = ₹824.32

Question 5: Average

The average of 6 numbers is 7. The average of 3 of them is 5. What is the average of the remaining 3 numbers?

Solution: Sum of 6 numbers = 6 × 7 = 42
Sum of 3 numbers = 3 × 5 = 15
Sum of remaining 3 = 42 - 15 = 27

Average of remaining 3 = 27/3 = 9

Question 6: Speed and Distance

A train travels at an average speed of 90 km/hr without stoppages and 75 km/hr with stoppages. How many minutes per hour does the train stop?

Solution: Difference in speed = 90 - 75 = 15 km/hr
Time to cover 15 km at 90 km/hr = (15/90) × 60 = 10 minutes

Question 7: Partnership

A and B invest in a business in the ratio 3:2. If 5% of the total profit goes to charity and A's share is ₹855, find the total profit.

Solution: Let total profit = P
Remaining after charity = 0.95P

A's share = (3/5) × 0.95P = 855
0.57P = 855
P = 855/0.57 = ₹1500

Question 8: Probability

A bag contains 4 white, 5 red, and 6 blue balls. Three balls are drawn at random. Find the probability that all of them are red.

Solution: Total balls = 15
Ways to draw 3 balls = C(15,3) = 455
Ways to draw 3 red balls = C(5,3) = 10

Probability = 10/455 = 2/91

Question 9: Number Series

Find the next number: 2, 5, 9, 19, 37, ?

Solution: Pattern: ×2+1, ×2-1, ×2+1, ×2-1, ×2+1
2 × 2 + 1 = 5
5 × 2 - 1 = 9
9 × 2 + 1 = 19
19 × 2 - 1 = 37
37 × 2 + 1 = 75

Question 10: Calendar

If today is Monday, what day will it be after 61 days?

Solution: 61 days = 8 weeks + 5 days
8 weeks brings us to Monday again
5 days after Monday = Saturday

Question 11: Percentage

If the price of sugar increases by 25%, by what percentage should consumption be decreased to maintain the same expenditure?

Solution: Reduction % = [R/(100+R)] × 100
= [25/125] × 100 = 20%

Question 12: Ratio

If A:B = 2:3, B:C = 4:5, and C:D = 6:7, find A:D.

Solution: A:B = 2:3 = 8:12
B:C = 4:5 = 12:15
C:D = 6:7 = 15:17.5

A:D = 8:17.5 = 16:35

Question 13: Age Problem

The ratio of ages of father and son is 7:2. After 10 years, the ratio will be 9:4. Find the son's present age.

Solution: Let father's age = 7x, son's age = 2x
(7x + 10)/(2x + 10) = 9/4
28x + 40 = 18x + 90
10x = 50
x = 5

Son's age = 2 × 5 = 10 years

Question 14: HCF LCM

Two numbers are in the ratio 3:5 and their LCM is 225. Find the numbers.

Solution: Let numbers be 3x and 5x
HCF = x
LCM = (3x × 5x)/x = 15x = 225
x = 15

Numbers are 45 and 75

Question 15: Boats and Streams

A boat goes 12 km upstream in 3 hours and 18 km downstream in 3 hours. Find the speed of the stream.

Solution: Upstream speed = 12/3 = 4 km/hr
Downstream speed = 18/3 = 6 km/hr

Speed of stream = (6 - 4)/2 = 1 km/hr

💻 Technical/CS Questions (10 Questions with Solutions)

Question 1: C Programming

What is the output?

#include <stdio.h>
int main() {
    int a = 5, b = 10;
    printf("%d", a+++++b);
    return 0;
}

Solution: This will result in a compilation error because a+++++b is parsed as a++ ++ +b which is invalid. There needs to be a space or different operator arrangement.

Question 2: Data Structures

What is the minimum number of queues needed to implement a stack?

Solution: A stack can be implemented using 2 queues. Push operation is O(1), pop operation is O(n) where we transfer all elements except the last from queue 1 to queue 2.

Alternatively, using 1 queue with costly push and O(1) pop is also possible.

Question 3: Operating Systems

What is a deadlock? What are the four necessary conditions?

Solution: A deadlock is a situation where two or more processes are unable to proceed because each is waiting for the other to release resources.

Four necessary conditions (Coffman conditions):

  1. Mutual Exclusion: Resources cannot be shared
  2. Hold and Wait: Process holds resources while waiting for more
  3. No Preemption: Resources cannot be forcibly taken
  4. Circular Wait: Circular chain of processes waiting

  • LEFT JOIN: Returns all rows from left table and matching rows from right table (NULL for non-matches)

Question 10: Cybersecurity

What is SQL Injection and how to prevent it?

Solution: SQL Injection is an attack where malicious SQL statements are inserted into application queries through user input.

Prevention methods:

  • Use parameterized queries/prepared statements
  • Input validation and sanitization
