Sample Qualcomm placement paper aptitude questions

Practice these sample aptitude questions from Qualcomm placement papers to understand the question types and difficulty level.

Quantitative aptitude questions

Q1: Percentage Problem

If the price of a commodity increases by 25% and then decreases by 20%, what is the net change in price?

Solution:

Let original price = ₹100
After 25% increase = ₹125
After 20% decrease = ₹125 × 0.80 = ₹100
Net change = 0% (no change)

Answer: No change (0%)

Q2: Ratio Problem

The ratio of the ages of A and B is 3:4. After 5 years, the ratio becomes 4:5. Find the present age of A.

Solution:

Let present ages: A = 3x, B = 4x
After 5 years: A = 3x + 5, B = 4x + 5
(3x + 5)/(4x + 5) = 4/5
5(3x + 5) = 4(4x + 5)
15x + 25 = 16x + 20
x = 5
Present age of A = 3x = 3 × 5 = 15 years

Answer: 15 years

Q3: Time and Work

A can complete a work in 12 days, B in 15 days. They work together for 4 days, then A leaves. How long will B take to complete the remaining work?

Solution:

A's rate = 1/12 per day
B's rate = 1/15 per day
Combined rate = 1/12 + 1/15 = (5+4)/60 = 9/60 = 3/20 per day


Work done in 4 days = 4 × 3/20 = 12/20 = 3/5
Remaining work = 1 - 3/5 = 2/5


Time for B to complete remaining = (2/5) / (1/15) = (2/5) × 15 = 6 days

Answer: 6 days

Q4: Profit and Loss

A shopkeeper marks his goods 30% above cost price but allows a discount of 10%. Find his profit percentage.

Solution:

Let CP = ₹100
Marked Price (MP) = ₹130 (30% above CP)
Discount = 10% of ₹130 = ₹13
Selling Price (SP) = ₹130 - ₹13 = ₹117
Profit = ₹117 - ₹100 = ₹17
Profit % = (17/100) × 100 = 17%

Answer: 17%

Logical reasoning questions

Q5: Syllogism

Statements: All roses are flowers. Some flowers are red. Conclusions: I. Some roses are red. II. All red things are roses.

Solution:

Analyzing the statements:

  • All roses are flowers (A → B)
  • Some flowers are red (B → C, some)

Conclusion I: Some roses are red - Valid Conclusion II: All red things are roses - Invalid

Answer: Only conclusion I follows

Q6: Data Sufficiency

What is the value of x? Statement I: x² - 7x + 12 = 0 Statement II: x > 2

Solution:

Statement I: x² - 7x + 12 = 0 (x - 3)(x - 4) = 0 x = 3 or x = 4

Statement II: x > 2 (both 3 and 4 satisfy this)

Combining both: x = 3 or x = 4 (both positive and > 2)

Answer: Both statements together are not sufficient to determine unique value of x

Verbal ability questions

Q7: Reading Comprehension

Read the passage and answer: “Digital transformation has reshaped businesses worldwide. Companies are adopting new technologies to improve efficiency and customer experience.”

What is the main idea of the passage?

Answer: Digital transformation is changing how businesses operate by adopting new technologies.

Q8: Grammar - Error Detection

Identify the error: “Neither of the students were present in the class.”

Solution:

"Neither" is singular, so it should be "was" not "were"
Correct: "Neither of the students was present in the class."

Answer: “were” should be “was”
