Question : If $N= \frac{(\sqrt6-\sqrt5)}{(\sqrt6+\sqrt5)}$, then what is the value of $(N+\frac{1}{N})$?
Option 1: 10
Option 2: 11
Option 3: 12
Option 4: 22
Correct Answer: 22
Solution : Given: $N= \frac{(\sqrt6-\sqrt5)}{(\sqrt6+\sqrt5)}$ $\frac{1}{N}= \frac{(\sqrt6+\sqrt5)}{(\sqrt6-\sqrt5)}$ To find: $(N+\frac{1}{N})$ Putting the values, we get: = $\frac{(\sqrt6-\sqrt5)}{(\sqrt6+\sqrt5)}+\frac{(\sqrt6+\sqrt5)}{(\sqrt6-\sqrt5)}$ = $\frac{(\sqrt6-\sqrt5)^2+(\sqrt6+\sqrt5)^2}{(\sqrt6+\sqrt5)(\sqrt6-\sqrt5)}$ = $\frac{6+5-2\sqrt6\sqrt5+6+5+2\sqrt6\sqrt5}{6-5}$ = 22 Hence, the correct answer is 22.

Question : A sells a car priced at Rs. 36000. He gives a discount of 8% on the first Rs. 20,000 and 5% on the remaining Rs. 16,000. B also sells a car of the same make, priced at Rs. 36000. He gives a discount of 7% on the total price. Calculate the actual prices charged by A and B for the cars.
Option 1: A = Rs. 33,500 B = Rs. 33,400
Option 2: A = Rs. 33,480 B = Rs. 33,600
Option 3: A = Rs. 33,450 B = Rs. 33,650
Option 4: A = Rs. 33,600 B = Rs. 33,480
Correct Answer: A = Rs. 33,600 B = Rs. 33,480
Solution : Selling price of A = Rs. 36000 Total discount by A = $20000 \times \frac{8}{100}+16000 \times \frac{5}{100}$ = 1600 + 800 = Rs. 2400 $\therefore$ Actual price charged by A = Rs. 36000 − Rs. 2400 = Rs.
