Question : If $x=\frac{3}{2}$, then the value of $27x^{3}-54x^{2}+36x-11$ is:
Option 1: $11\frac{3}{8}$
Option 2: $11\frac{5}{8}$
Option 3: $12\frac{3}{8}$
Option 4: $12\frac{5}{8}$
Correct Answer: $12\frac{5}{8}$
Solution : Given: $27x^{3}–54x^{2}+36x–11$ Putting the value of $x=\frac{3}{2}$ in the above equation $27×(\frac{3}{2})^{3}–54×(\frac{3}{2})^{2}+36×\frac{3}{2}–11$ = $27×(\frac{27}{8})–54×(\frac{9}{4})+36×\frac{3}{2}–11$ = $\frac{729}{8}–\frac{486}{4}+\frac{108}{2}–11$ = $\frac{729–972+432–88}{8}$ = $\frac{101}{8}$ = $12\frac{5}{8}$ Hence, the correct answer is $12\frac{5}{8}$.

Solution : Cost price = Rs. 1,260 Selling price = Rs. 1,197 Loss = 1260 – 1197 = Rs. 63 So, the loss percentage = $\frac{63}{1260}×100$ = 5% Hence, the correct answer is 5%.
Question : What is the volume of a cylinder if the radius of the cylinder is 10 cm and the height is 20 cm? (Take π = 3.14)
Option 1: 6280 cm3
Option 2: 5306 cm3
Option 3: 6260 cm3
Option 4: 5280 cm3
Correct Answer: 6280 cm3
Solution : The radius of the cylinder, $r$ = 10 cm Height, $h$ = 20 cm Volume of the cylinder = $\pi r^2 h$ = 3.14 × 102 × 20 = 6280 cm3 Hence, the correct answer is 6280 cm3.
