Question : When a discount of 25% is given on a cruise trip, the profit is 41%. If the discount is 26%, then the profit is:
Option 1: 39.12%
Option 2: 67%
Option 3: 94.88%
Option 4: 11.24%
Correct Answer: 39.12%
Solution : Let the cost price be Rs. 100. When profit % = 41, selling price = 100 + 41 = Rs. 141 When discount = 25%, selling price = 75% of Marked price Marked price = $\frac{141}{\frac{75}{100}}$ = $\frac{141}{\frac{3}{4}}$ = $\frac{141 × 4}{3}$ = Rs. 188
Question : R jogs at twice the speed of walking and runs at twice the speed of jogging. From his home to office, he covers half of the distance by walking and the rest by jogging. From his office to home, he covers half the distance jogging and the rest by running. What is his average speed (in km/hr) in a complete round from his home to office and back home if the distance between his office and home is 10 km and he walks at the speed of 5 km/hr?
Option 1: $\frac{90}{8}$
Option 2: $\frac{60}{8}$
Option 3: $\frac{60}{9}$
Option 4: $\frac{80}{9}$
Correct Answer: $\frac{80}{9}$
Solution : R's jogging speed = 5 × 2 = 10 km/hr R's running speed = 10 × 2 = 20 km/hr Now, At the time of going to his office time taken $= \frac{5}{5} + \frac{5}{10} =1 + 0.5 = 1.5$ hours At the time of

Correct Answer: 742.85
Solution : $\therefore$ Average Marked price $= \frac{1100+700+900+600+400+500+1000}{7}=\frac{5200}{7}= 742.85$ Hence, the correct answer is 742.85.
Question : If $x=\sqrt[3]{28}, y=\sqrt[3]{27}$, then the value of $x+y-\frac{1}{x^{2}+xy+y^{2}}$ is:
Option 1: 8
Option 2: 7
Option 3: 6
Option 4: 5
Correct Answer: 6
Solution : Given: $x=\sqrt[3]{28}$ and $y=\sqrt[3]{27}.$ To find $x+y–\frac{1}{x^{2}+xy+y^{2}}$ Multiplying and dividing by $(x–y)$ $=x+y–\frac{(x–y)}{(x–y)(x^{2}+xy+y^{2})}$ $=x+y–\frac{(x–y)}{(x^{3}–y^{3})}$ $=x+y–\frac{(x–y)}{(28–27)}$ $=x+y–x+y$ $=2y$ $=2×\sqrt[3]{27}$ $=2×3 = 6$ Thus, $x+y-\frac{1}{x^{2}+xy+y^{2}}=6$ Hence, the correct answer is 6.
Question : Directions: Select the option that is related to the fifth number in the same way as the second number is related to the first number and the fourth number is related to the third number. 5 : 45 :: 3 : 3 :: 6 : ?
