Question : If $x+\frac{1}{x}=2$, then the value of $x^{57}+\frac{1}{x^{57}}$ is:
Option 1: 1
Option 2: –2
Option 3: 0
Option 4: 2
Correct Answer: 2
Solution : Given, $x+\frac{1}{x}=2$ ⇒ $x^2 + 1 = 2x$ ⇒ $x^2-2x+1 = 0$ ⇒ $(x-1)^2 = 0$ ⇒ $x-1 = 0$ ⇒ $x=1$ $\therefore x^{57}+\frac{1}{x^{57}}=1^{57}+\frac{1}{1^{57}} = 2$ Hence, the correct answer is 2.
Question : Two shopkeepers announced the same price of Rs. 700 for a sewing machine. The first offers successive discounts of 30% and 6%, while the second offers successive discounts of 20% and 16%. The difference in their selling prices is:

Option 2: Rs. 16.80
Option 3: Rs. 22.40
Option 4: Rs. 36.40
Correct Answer: Rs. 9.80
Solution : The price of the sewing machine = Rs. 700 Single discount of 30% and 6% = $30+6-\frac{30\times 6}{100} = 36-1.8 =34.2\%$ Single discount of 20% and 16% = $20+16-\frac{20\times 16}{100} = 36-3.2 =32.8\%$ Difference of discount percentage = $34.2 -32.8 =1.4\%$ $\therefore$ The difference
