Question : Disha takes 12 hours to copy a 75-page manuscript, while Mohit can copy the same manuscript in 10 hours. How many hours will it take for them to copy a 150-page manuscript if they work together?
Option 1: $10 \frac{10}{11}$ hours
Option 2: $9 \frac{9}{11}$ hours
Option 3: $8 \frac{9}{11}$ hours
Option 4: $11 \frac{8}{11}$ hours
Correct Answer: $10 \frac{10}{11}$ hours
Solution : Given: Time taken by Disha = 12 hours Time taken by Mohit = 10 hours Total work = LCM of (12, 10) = 60 units 60 units = 75 pages ⇒ 120 units = 150 pages Efficiency of Disha = $\frac{60}{12}$ = 5
Question : The marked price of an item is 25% more than that of its cost price. If a discount of 10% is given on the marked price, then the gain percentage is:
Option 1: $10 \frac{1}{2}$%
Option 2: $9 \frac{1}{2}$%
Option 3: $13 \frac{1}{2}$%
Option 4: $12 \frac{1}{2}$%
Correct Answer: $12 \frac{1}{2}$%
Solution : Let Rs. 100 be the cost price. Marked price = 100 + 25 = Rs. 125 Discount = 10% Selling price = 90% of marked price = 0.9 × 125 = Rs. 112.5 Profit = 112.5 – 100 = 12.5 Profit% = $\frac{12.5}{100}×100$ =

Question : If $\frac{x+1}{x-1}=\frac{a}{b}$ and $\frac{1-y}{1+y}=\frac{b}{a}$, then the value of $\frac{x-y}{1+xy}$ is:
Option 1: $\frac{2ab}{a^{2}-b^{2}}$
Option 2: $\frac{a^{2}-b^{2}}{2ab}$
Option 3: $\frac{a^{2}+b^{2}}{2ab}$
Option 4: $\frac{a^{2}-b^{2}}{ab}$
Correct Answer: $\frac{2ab}{a^{2}-b^{2}}$
Solution : $\frac{x+1}{x-1}=\frac{a}{b}$ ⇒ $bx+b = ax-a$ ⇒ $x = \frac{a+b}{a-b}$ Multiplying and dividing by $(a+b)$ in RHS, we get: ⇒ $x=\frac{(a+b)^2}{a^2-b^2}$ ----------------(i) Again, $\frac{1-y}{1+y}=\frac{b}{a}$ ⇒ $a-ay = b+by$ ⇒ $y=\frac{a-b}{a+b}$ Multiplying and diving by $(a-b)$ in RHS, we get: ⇒ $y=\frac{(a-b)^2}{a^2-b^2}$----------------(ii) From (i) and (ii), $\frac{x-y}{1+xy}$

Option 1: 50
Option 2: 30
Option 3: 60
Option 4: 40
Correct Answer: 50
Solution : Cost price of 60 chairs = Rs. 24,560 Cost price of a chair = Rs. $\frac{24560}{60}$ Selling price of a chair after 20% profit = $\frac{24560}{60}\times \frac{120}{100} = \frac{24560}{50}$ Number of chairs sold in Rs. 24,560 =$\frac{24560}{\frac{24560}{50}}=50$ Hence, the correct answer is 50.
