Quantitative aptitude (2024)

Q1: Age ratio

Problem: The ratio of ages of A and B is 3:5. After 8 years the ratio becomes 5:7. Find A’s present age.

Solution: Let ages be 3x and 5x. (3x+8)/(5x+8) = 5/7 7(3x+8) = 5(5x+8) 21x + 56 = 25x + 40 4x = 16 → x = 4 A’s age = 12 years.

Answer: 12 years

Q2: Pipe fill

Problem: Pipe A fills a tank in 6 hours and pipe B in 8 hours. How long do they take together to fill it?

Solution: Combined rate = 1/6 + 1/8 = 4/24 + 3/24 = 7/24. Time = 24/7 hours ≈ 3 hours 26 minutes.

Answer: 24/7 hours

Q3: Simple interest

Problem: Find the simple interest on ₹8000 at 10% per annum for 2 years.

Solution: SI = (P × R × T) / 100 = (8000 × 10 × 2) / 100 = ₹1600.

Answer: ₹1600

Q4: Percentage recover

Problem: If 30% of a number is 150, what is the number?

Solution: 0.3x = 150 → x = 150 / 0.3 = 500.

Answer: 500

Q5: Average after replace

Problem: The average of five numbers is 20. One number 30 is replaced by 10. What is the new average?

Solution: Old sum = 5 × 20 = 100. New sum = 100 − 30 + 10 = 80. New average = 80 / 5 = 16.

Answer: 16

Q6: Series n(n+1)

Problem: Find the next term: 2, 6, 12, 20, 30, ?

Solution: Pattern: 1×2, 2×3, 3×4, 4×5, 5×6, 6×7. Next = 6 × 7 = 42.

Answer: 42

Q7: Deck probability

Problem: What is the probability of drawing an ace from a standard 52-card deck?

Solution: There are 4 aces in 52 cards. Probability = 4/52 = 1/13.

Answer: 1/13

Q8: Net percent change

Problem: A number is increased by 20% and then decreased by 20%. What is the net percentage change?

Solution: Start with 100 → 120 → 96. Net change = 4% decrease. Formula: successive +a then −a gives −(a²/100)% = −4%.

Answer: 4% decrease

Coding practice (2024)

Coding Q1: Merge overlapping intervals

Problem: Given a list of intervals [start, end], merge all overlapping intervals and return the non-overlapping set that covers the same ranges.

Approach: Sort by start time. Walk once, merging into the last interval in the result when the next start is ≤ current end; otherwise append a new interval.

Complexity: O(n log n) time from the sort

Synopsys tip: Restate the problem, sketch a brute-force idea, then tighten it. Call out edge cases (empty input, single element, overflow) before you write code.

Coding Q2: Top K frequent elements

Problem: Given an integer array and an integer k, return the k most frequent elements. Order among equals can be arbitrary unless the problem says otherwise.

Approach: Count frequencies with a hash map, then use a heap of size k (or bucket sort by frequency) to extract the top k keys.

Complexity: O(n log k) with a heap

Synopsys tip: Restate the problem, sketch a brute-force idea, then tighten it. Call out edge cases (empty input, single element, overflow) before you write code.

Coding Q3: Linked list cycle

Problem: Given the head of a linked list, return true if there is a cycle and false otherwise.

Approach: Floyd’s tortoise and hare: move one pointer one step and another two steps. If they meet, a cycle exists. If the fast pointer hits null, there is no cycle.

Complexity: O(n) time, O(1) space

Synopsys tip: Restate the problem, sketch a brute-force idea, then tighten it. Call out edge cases (empty input, single element, overflow) before you write code.

Coding Q4: Binary tree level order

Problem: Given the root of a binary tree, return the level-order traversal (breadth-first) as a list of levels.

Approach: Use a queue. For each level, drain the current queue size, collect values, and enqueue children for the next level.

Complexity: O(n) time, O(n) space

Synopsys tip: Restate the problem, sketch a brute-force idea, then tighten it. Call out edge cases (empty input, single element, overflow) before you write code.

Coding Q5: Coin change (min coins)

Problem: Given coin denominations and an amount, return the fewest coins needed to make that amount, or -1 if it is impossible.

Approach: Unbounded knapsack DP: let dp[x] be the minimum coins for amount x. For each coin, update dp[c..amount]. Initialize dp[0] = 0 and the rest to a large sentinel.

Complexity: O(amount × coins)

Synopsys tip: Restate the problem, sketch a brute-force idea, then tighten it. Call out edge cases (empty input, single element, overflow) before you write code.

Coding Q6: Binary search

Problem: Given a sorted array of distinct integers and a target, return the index of target or -1 if missing.

Approach: Maintain lo/hi. Compare mid with target and shrink the half that cannot contain it. Careful with overflow-free mid and empty arrays.

Complexity: O(log n) time

Synopsys tip: Restate the problem, sketch a brute-force idea, then tighten it. Call out edge cases (empty input, single element, overflow) before you write code.

Coding Q7: Move zeros

Problem: Move all zeros in an array to the end while keeping the relative order of non-zero elements.

Approach: Two pointers: write non-zeros toward the front, then fill the remainder with zeros. Or swap zeros as you scan.

Complexity: O(n) time, O(1) space

Synopsys tip: Restate the problem, sketch a brute-force idea, then tighten it. Call out edge cases (empty input, single element, overflow) before you write code.

Coding Q8: Rotate array

Problem: Rotate an array to the right by k steps. Example: [1,2,3,4,5,6,7], k = 3 → [5,6,7,1,2,3,4].

Approach: Normalize k %= n. Reverse the whole array, reverse the first k elements, then reverse the rest. That yields the rotation in place.

Complexity: O(n) time, O(1) space

Synopsys tip: Restate the problem, sketch a brute-force idea, then tighten it. Call out edge cases (empty input, single element, overflow) before you write code.

Deep prep notes for Synopsys

How the Synopsys online test usually feels

Students usually say the first round is time-tight - easy marks vanish if you sit too long on one hard question. For Synopsys, skim the paper in a couple of minutes, mark what you can finish cleanly, and protect accuracy. Languages people commonly use: C++, Python, SystemVerilog (role-dependent).

Topic weight hints

Area Why it matters at Synopsys
DSA What usually helps you clear the first round
Core CS (OOPs / DBMS / OS) Technical interview depth
EDA, Semiconductor IP awareness Helps in managerial / HR conversations
Communication Explain your approach clearly; keep a few real examples ready for HR
