Aptitude Questions (15 with Solutions)

Q1: A person travels 40km at 8km/h and 30km at 6km/h. Average speed?

Solution: Total distance = 70km, Time = 5+5 = 10h. Average = 7 km/h

Q2: A and B can do work in 20 days, B and C in 30 days, C and A in 40 days. All together?

Solution: 2(A+B+C) = 1/20 + 1/30 + 1/40 = 13/120. A+B+C = 13/240. Time = 240/13 ≈ 18.5 days

Q3: A shopkeeper marks 25% above CP and gives 10% discount. Profit%?

Q4: LCM of two numbers is 180, HCF is 6. One number is 36. Find other.

Solution: Product = LCM × HCF = 1080. Other number = 1080/36 = 30

Q5: A sum becomes 3 times in 8 years at SI. When will it become 5 times?

Solution: SI=2P in 8 years. For 4P (to become 5P), time = 16 years

Q6: Probability of drawing two kings from deck without replacement.

Solution: (4/52) × (3/51) = 1/221

Solution: Squares: 36

Q8: A man rows 12km upstream in 3 hours, downstream in 2 hours. Stream speed?

Solution: Upstream = 4km/h, Downstream = 6km/h. Stream = (6-4)/2 = 1 km/h

Q9: Average of first 10 multiples of 7.

Solution: 7(1+2+...+10)/10 = 7×55/10 = 38.5

Solution: Ratio: 20000×6 : 30000×4 = 120000:120000 = 1:1. A's share = ₹4200

Q11: Statement: All birds can fly. Ostrich is a bird. Conclusion: Ostrich can fly.

Solution: Logically follows from premises (though factually incorrect). Conclusion follows

Q12: Coding: BAD=7, CAB=6. Find DAD.

Solution: Positions: B(2)+A(1)+D(4)=7. C(3)+A(1)+B(2)=6. D(4)+A(1)+D(4)=9

Q13: A is 12m east of B. C is 5m north of A. Distance BC?

Solution: √(12²+5²) = √(144+25) = 13m

Q14: Find odd: 3, 9, 27, 81, 243, 725

Solution: Powers of 3. 3⁶=729, not 725. 725 is odd

Q15: In a row, A is 12th from left, 15th from right. Total students?

Solution: 12+15-1 = 26

Technical Questions (10 with Solutions)

Q1: What is the difference between microcontroller and microprocessor?

Solution: Microcontroller has CPU, memory, I/O on single chip. Microprocessor is just CPU, needs external components.

Q2: Explain embedded C vs standard C.

Solution: Embedded C has extensions for hardware access, fixed-point arithmetic, multiple memory spaces.

Q3: What is interrupt handling?

Solution: Mechanism where processor pauses current execution to handle high-priority events, then resumes.

Q4: Difference between SPI and I2C?

Solution: SPI: 4-wire, full duplex, faster, master-slave. I2C: 2-wire, half duplex, slower, multi-master.

Q5: What is DMA?

Solution: Direct Memory Access allows peripherals to transfer data without CPU involvement.

Q6: Explain watchdog timer.

Solution: Hardware timer that resets system if not periodically serviced - detects software hangs.

Q7: What is PWM?

Solution: Pulse Width Modulation - technique to control power delivery by varying duty cycle.

Q8: Difference between stack and heap?

Solution: Stack: automatic, fixed size, LIFO. Heap: dynamic, larger, manual management.

Q9: What is CAN bus?

Solution: Controller Area Network - robust vehicle bus standard for automotive communications.
