Question : A supermarket earns $5\frac{1}{2}$% as a discount on the total purchasing value and a bonus of $\frac{1}{2}$% on sales more than Rs. 10,000. What is the total sale value if it earns Rs. 1,990?
Option 1: Rs. 14,000
Option 2: Rs. 16,000
Option 3: Rs. 34,000
Option 4: Rs. 24,000
Correct Answer: Rs. 34,000
Solution : Let the total sales be $x$. Discount on total purchasing value = 5.5% Bonus on sales more than 10000 = 0.5% 0.5% on $(x-10000)=\frac{0.5(x-10000)}{100}$ Given earning = 1990 According to the question: ⇒ $\frac{5.5x}{100}+\frac{0.5(x-10000)}{100}=1990$ ⇒ $6x=199000+5000$ $\therefore x=34000$ Hence, the correct answer is Rs.

Question : $\frac{(100-1)(100-2)(100-3)....(100-200)}{100\times99\times98...3\times2\times1}$ is equal to:
Option 1: $\frac{100}{99\times98\times97\times...\times3\times2\times1}$
Option 2: $\frac{1}{99\times98\times97\times...\times3\times2\times1}$
Option 3: $0$
Option 4: $\frac{2}{99\times98\times97\times...\times3\times2\times1}$
Correct Answer: $0$
Solution : Given: $\frac{(100-1)(100-2)(100-3)....(100-200)}{100\times99\times98...3\times2\times1}$ ⇒ $\frac{(100-1)(100-2)(100-3).....(100-100).....(100-200)}{100\times99\times98...3\times2\times1}$ This will be equal to zero, as there will be a term in between $(100 – 100)$ equal to zero. Hence, the correct answer is $0$.
