Sample IOCL Graduate Engineer Civil questions with solutions
From the free tests in this series — the rest of the series is written the same way.
Quantitative Aptitude
1. A container has 80 litres of a mixture containing 25% water. How much pure milk should be added so that water becomes 20% of the final mixture?
- A.20 litres
- B.30 litres
- C.25 litres
- D.15 litres
Show answer & solution
Answer: A
Water present = 25% of 80 = 20 litres. Let x litres of milk be added. Then 20/(80 + x) = 0.20. Hence 80 + x = 100 and x = 20 litres.
Surveying
2. The Transit Rule for adjusting a closed traverse is mathematically preferred over Bowditch's rule when which operational condition is true?
- A.Lengths are measured more precisely than angles
- B.Coordinates are corrected for declination
- C.Angles are measured more precisely than lengths
- D.The traverse is open and runs straight
Show answer & solution
Answer: C
The transit rule is used when angular measurements are more precise than linear measurements (e.g., using a high-accuracy theodolite alongside ordinary chaining), distributing errors without changing the measured angles significantly.
Quantitative Aptitude
3. A trader mixes two types of oil costing Rs 90 per litre and Rs 120 per litre. At what ratio should they be mixed so that by selling the mixture at Rs 115.50 per litre, he gains 10%?
- A.3:2
- B.2:3
- C.2:1
- D.1:1
Show answer & solution
Answer: D
For a 10% gain, cost price of the mixture = 115.50/1.10 = Rs 105 per litre. By alligation, Rs 90 oil : Rs 120 oil = (120 − 105) : (105 − 90) = 15 : 15 = 1 : 1.
