Reasoning
All cats are animals. Some animals are dogs. Therefore, some cats are dogs. Is the conclusion valid?
The conclusion is invalid. While all cats are animals and some animals are dogs, there is no information linking cats directly to dogs. The conclusion cannot be logically derived from the given statements.
Quantitative
If 3x + 5 = 20, then x equals:
3x = 15 → x = 5.
Quantitative
A bank offers a loan of ₹50,000 at 8% per annum simple interest. What is the interest after 2 years?
Correct answer: ₹8,000
Reasoning
Odd one out: Triangle, Square, Circle, Rectangle
Circle has no straight sides.
Verbal
Synonym of "Crucial":
Crucial means important.
Reasoning
Complete the series: AZ, BY, CX, ?
First letter +1, second −1 → DW.
Quantitative
If a number is increased by 20% and then decreased by 15%, what is the net change?
Correct answer: +2% increase
Quantitative
The ratio of ages of A and B is 3:5. After 8 years, the ratio becomes 5:7. Find the present age of A.
Let present ages be 3x and 5x. After 8 years: - A's age: 3x + 8 - B's age: 5x + 8 Given: (3x + 8)/(5x + 8) = 5/7 7(3x + 8) = 5(5x + 8) 21x + 56 = 25x + 40 4x = 16 x = 4 Present age of A = 3x = 3 × 4 = 12 years
Reasoning
If letter positions are summed (A=1…Z=26), TEAM equals:
Sum of positions = 39.
Verbal
Find synonym of "Courageous"
Correct answer: Brave
Quantitative
A sum doubles in 5 years at simple interest. The rate of interest is:
For doubling, RT = 100 → R = 100/5 = 20%.
Reasoning
Which comes next: 5, 10, 20, 40, ?
Each term doubles → 80.
Verbal
The idiom "under the weather" means:
It means: feeling ill.
Quantitative
The LCM of 12 and 18 is:
LCM(12,18) = 36.
Verbal

Deep Prep Notes for Intel
Section titled “Deep Prep Notes for Intel”How the Intel Online Assessment Usually Feels
Section titled “How the Intel Online Assessment Usually Feels”Candidates describe a paced filter where easy marks disappear if you over-invest in one hard item. For Intel, start with a three-minute scan, mark certainty levels, and protect accuracy. Languages typically include C, C++, Python, Verilog (role-dependent).
