Question : The volume of a solid right circular cylinder of height 8 cm is $392 \pi$ cm3. Its curved surface area (in cm2) is:
Option 1: $161 \pi$
Option 2: $96 \pi$
Option 3: $210 \pi$
Option 4: $112 \pi$
Correct Answer: $112 \pi$
Solution : The volume $V$ of a right circular cylinder is given by the formula $V = \pi r^2 h$, where $r$ is the radius and $h$ is the height. Given that $V = 392\pi \;\text{cm}^3$ and $h = 8 \;\text{cm}$. $⇒392\pi = \pi r^2 \times
Question : The following figure shows the different expenses that are incurred in manufacturing toys. If the total expenditure is INR 3,00,000, then how much expenditure was incurred on Material Cost and Selling Expenses (in INR)?

Question : In a linear race of 500 m, A can beat B by 50 m, and in a race of 600 m, B can beat C by 60 m. By how many metres will A beat C in a race of 400 m?
Option 1: 70
Option 2: 68
Option 3: 76
Option 4: 72
Correct Answer: 76
Solution : A can beat B by 50 m in a race of 500 m. If A is at 500 m, then B = 500 – 50 = 450 m So, A: B = 500: 450 = 10: 9 = 100: 90 ---------(i) B can beat C
