Question : A tradesman marks his goods at 25% above the cost price. If he reduces the marked price by $12\frac{1}{2}\%$, then his profit will be:
Option 1:
$9\frac{3}{8}\%$
Option 2: $7\frac{3}{5}\%$
Option 3: $6\frac{3}{8}\%$
Option 4: $5\frac{1}{3}\%$
Correct Answer:
Solution : Use the successive percentage change formula, where $x$ and $y$ are percentage increases or decreases, if increases take positive and if decreases take negative. $=(x+y+\frac{xy}{100})\%$ We have, $x = 25\%$ and $y=-12\frac{1}{2}\%=-\frac{25}{2}\%$ The required profit percentage, $=(25-\frac{25}{2}-\frac{25×25}{200})\%$ $=(25-\frac{25}{2}-\frac{25}{8})\%$ $=\frac{75}{8}\%$ $=9\frac{3}{8}\%$ Hence, the correct answer is
Question : Rajinder drives his car at an average speed of 40 km/hr to cover half of his total distance and thereafter he increases his speed to 60 km/hr. He covers his journey in 7 hours. What is the average speed of Rajinder on this journey?
Option 1: 52 km/hr
Option 2: 48 km/hr
Option 3: 50 km/hr
Option 4: 54 km/hr
Correct Answer: 48 km/hr
Solution : Let the total distance covered by Rajinder = $2x$ km Time taken to travel half distance = $\frac{x}{40}$ Time taken to travel other half distance = $\frac{x}{60}$ Average speed = $\frac{\text{Total distance travelled}}{\text{Total time taken}}$ = $\frac{2x}{\frac{x}{40}+\frac{x}{60}}$ = $\frac{2×40×60}{40+60}$ = 48 km/hr Hence, the
