Others are perfect cubes; 100 is not.
Reasoning
Find next number: 2, 5, 10, 17, 26, ?
Pattern: Differences are 3, 5, 7, 9 (odd numbers) Next difference = 11 Next number = 26 + 11 = 37

Solution: Product of numbers = HCF × LCM. 36 × other = 12 × 180 = 2160. Other = 2160 / 36 = 60.
Answer: 60
Q2: 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
Q3: Pipe empty
Problem: A pipe fills in 8 hours; a leak empties in 12. Time to fill with both open?

Answer: 24 hours
Q4: SI three years
Problem: Find simple interest on ₹5000 at 8% per annum for 3 years.
Solution: SI = 5000 × 8 × 3 / 100 = ₹1200.
Answer: ₹1200
Q5: Consecutive integers
Problem: If the sum of three consecutive integers is 72, what is the smallest of these integers?
Solution: Let the integers be x, x+1, and x+2.
x + (x+1) + (x+2) = 72 3x + 3 = 72 3x = 69 x = 23
So the integers are 23, 24, and 25.
Answer: 23
Q6: Work efficiency
Problem: A is twice as efficient as B. Together they finish in 12 days. How many days does A alone need?
Solution: Let B = x days, A = x/2. 1/(x/2) + 1/x = 1/12 → 2/x + 1/x = 1/12 → 3/x = 1/12 → x = 36. A alone = 18 days.
Answer: 18 days
Q7: 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
Q8: Profit false weight
Problem: A seller uses 900 g weight for 1 kg and sells at cost price. Profit %?
