The SBI PO Percentages Quiz includes exam-level questions prepared according to the latest exam pattern, helping candidates improve calculation speed, accuracy, and confidence.
Q1. Find 35% of 480.
35% of 480 = (35 ÷ 100) × 480
= 0.35 × 480
= 168
Answer: 168
Q2. A salary increases from ₹40,000 to ₹46,000. Find the percentage increase.
Increase in salary = ₹46,000 − ₹40,000
= ₹6,000
Percentage increase = (Increase ÷ Original Salary) × 100
= (₹6,000 ÷ ₹40,000) × 100
= 15%
Answer: 15%
Q3. The price of a product increases by 20% and then decreases by 20%. What is the net percentage change?
Net percentage change = x + y + (xy ÷ 100)
Here, x = 20 and y = −20
Net change = 20 − 20 + [(20 × −20) ÷ 100]
= 0 − 4
= −4%
Answer: 4% decrease
Q4. A candidate scores 360 marks and fails by 40 marks. If the passing percentage is 50%, find the maximum marks.
Passing marks = Marks scored + Marks required to pass
= 360 + 40
= 400 marks
50% of maximum marks = 400
Maximum marks = (400 × 100) ÷ 50
= 800 marks
Answer: 800 marks
Q5. The population of a town is 50,000. It increases by 10% in the first year and 20% in the second year. Find the new population.
Population after the first year:
= 50,000 × 1.10
= 55,000
Population after the second year:
= 55,000 × 1.20
= 66,000
Answer: 66,000
