Answers with Explanations
- Correct Answer: 2
Increase by 10% → 40,000 × 1.1 = 44,000
Decrease by 10% → 44,000 × 0.9 = 39,600
- Correct Answer: 1
Total parts = 3 + 5 = 8
Each part = 240/8 = 30
Boys = 3 × 30 = 90
- Correct Answer: 3
Total marks = 5 × 102 = 510
Remaining marks = 510 − 110 = 400
Average = 400/4 = 100
- Correct Answer: 2
25% of 4000 = 1000 (discount offered)
Selling price = 4000 − 1000 = ₹3,000
- Correct Answer: 4
Upstream speed = 45/3 = 15 km/h
Downstream speed = 45/2 = 22.5 km/h
Current speed = (22.5 − 15) / 2 = 3.75 km/h
- Correct Answer: 3
Spent = 70%, remaining = 30%
30% = 9000 → 100% = 9000 / 30 × 100 = ₹30,000
- Correct Answer: 3
Increase = 50 (250-200)
Percentage = (50/200) × 100 = 25%
- Correct Answer: 3
English = 65/100 × 100 = 65%
Mathematics = (78/120) × 100 = 65%
- Correct Answer: 2
Original no. of workers × Original no. of days = New no. of workers × New no. of days
8 × 15 = 12 × x
x = 10 days
- Correct Answer: 1
Original total age = 6 × 30 = 180
New total age = 7 × 32 = 224
Age of the 7th member= 224 − 180 = 44 years
- Correct Answer: 4
Side = 72 ÷ 4 = 18
Area = 18² = 324
- Correct Answer: 2
Cost Price of 15 pens = Selling Price of 12 pens
Gain on 12 pens = Cost Price of 3
Gain% = (3/12) × 100 = 25%
- Correct Answer: 2
Reduction of 20% in quantity of tablets means that 80% of tablets were actually purchased.
So, 80% of 4,000 = 3,200
- Correct Answer: 3
Total items = 4 + 3 + 5 = 12
Neither law journal nor newspaper = only economics magazines = 3
Probability = 3/12 = ¼
15.Correct Answer: 3
Percentage of students who failed = 25% = 15 (given)
Total strength of the class = 100% = 15 × 100/25 = 15 × 4 = 60 students
