Question : Manoj marked his goods 30% above the cost price and gave a 12% discount to the customers. The profit or loss percentage is:
Option 1: 14.8% loss
Option 2: 15.4% profit
Option 3: 14.4% profit
Option 4: 15% loss
Correct Answer: 14.4% profit
Solution : Let the cost price be $x$. Manoj marked his goods 30% above the cost price. So, the marked price $=\frac{130}{100}x=\frac{13x}{10}$ He then gave a 12% discount on the marked price. The selling price $=\frac{100-12}{100}×\frac{13x}{10}=\frac{143x}{125}$ Since the selling price is more than the cost price,
Question : A person, who spends 68% of his monthly income, can save INR 14,720 per month. Find his total expenses.
Option 1: INR 46,000
Option 2: INR 38,210
Option 3: INR 31,280
Option 4: INR 42,400
Correct Answer: INR 31,280
Solution : Given: A person spends 68% of his monthly income. Savings = INR 14,720 per month. Expenditure = 68% Savings = 100 – 68 = 32% So, 32% = INR 14720 ⇒ 1% = $\frac{14720}{32}$ = INR 460 ⇒ 68% = 460 × 68 =
Question : If $\frac{x}{y}=\frac{a+2}{a-2}$, then the value of $\frac{x^{2}-y^{2}}{x^{2}+y^{2}}$ is:
Option 1: $\frac{4a}{a^{2}+2}$
Option 2: $\frac{2a}{a^{2}+2}$
Option 3: $\frac{4a}{a^{2}+4}$
Option 4: $\frac{2a}{a^{2}+4}$
Correct Answer: $\frac{4a}{a^{2}+4}$
Solution : Given: $\frac{x}{y}=\frac{a+2}{a-2}$ Let $x = a+2$ and $y=a-2$, Now, $\frac{x^{2}-y^{2}}{x^{2}+y^{2}}$ = $\frac{(a+2)^{2}-(a-2)^{2}}{(a+2)^{2}+(a-2)^{2}}$ = $\frac{(a^{2}+4a+4)-(a^{2}-4a+4)}{(a^{2}+4a+4)+(a^{2}-4a+4)}$ = $\frac{8a}{2a^{2}+8}$ = $\frac{4a}{a^{2}+4}$ Hence, the correct answer is $\frac{4a}{a^{2}+4}$.
