Question : If $\sqrt[2]{0.014\times0.14x}=0.014\times0.14\sqrt[2]{y}$, then find the value of $\frac{x}{y}$?
Option 1: 0.000196
Option 2: 0.00196
Option 3: 0.0196
Option 4: 0.196
Correct Answer: 0.00196
Solution : Given: $\sqrt[2]{0.014\times0.14x}=0.014\times0.14\sqrt[2]{y}$ $\frac{\sqrt[2]{0.014\times0.14x}}{\sqrt[2]{y}}=0.014\times0.14$ $\sqrt[2]{\frac{x}{y}}=\frac{0.014\times0.14}{\sqrt[2]{0.014\times0.14}}$ $\sqrt[2]{\frac{x}{y}}=\sqrt[2]{0.014\times0.14}$ Squaring on the both sides of the equation, we get, $(\sqrt[2]{\frac{x}{y}})^2=(\sqrt[2]{0.014\times0.14})^2$ ${\frac{x}{y}}={0.014\times0.14}$ ${\frac{x}{y}}=0.00196$ Hence, the correct answer is 0.00196.

Question : The average of ten numbers is 72. The average of the first four numbers is 69 and that of the next three numbers is 74. The 8th number is 6 more than the 9th number and 12 more than the 10th number. What is the average of the 8th and 9th numbers?
Option 1: 76
Option 2: 76.5
Option 3: 77
Option 4: 77.5
Correct Answer: 77
Solution : Let 8th number be $x$. So, 9th number be $(x - 6)$ and 10th number be $(x - 12)$ The average of 10 numbers = 72 $\therefore$ Sum of 10 numbers = 72 × 10 = 720 According to the question, The
