Option 1: 20%
Option 2: 25%
Option 3: 15%
Option 4: 44%
Correct Answer: 20%
Solution : When compounded annually, $ A= P(1+\frac{R}{100})^{T}$, Where $A$ is the total amount, $P$ is the principal amount, $R$ is the rate of interest per annum, and $T$ is the time in years. According to the question, $P(1+\frac{R}{100})^2-P(1+\frac{R}{100})=400$ -----------------(1) $P(1+\frac{R}{100})^4-P(1+\frac{R}{100})^3=576$ -----------------(2) From equation (1) we get,
Question : The radius of a cylinder is 14 cm. If the height of the cylinder is four times of its radius, then what is the curved surface area of the cylinder?
Option 1: 5546 cm2
Option 2: 4928 cm2
Option 3: 4694 cm2
Option 4: 5214 cm2
Correct Answer: 4928 cm2
Solution : Given that: $r= 14$ cm and $h = 4r= 4 × 14 = 56$ cm $\therefore$ Curved surface of the cylinder = $2\pi r h=2 \times \frac{22}{7} \times 14 \times 56 = 4928$ cm2 Hence, the correct answer is 4928 cm2
