Question : A shopkeeper offers the following two discount schemes. A) Two successive discounts of 10% and 15% B) Buy 5 get 2 free. Which scheme has the maximum discount percentage?
Option 1: B does not give any discount
Option 2: B
Option 3: A and B both have the same discount percentage
Option 4: A
Correct Answer: B
Solution : For the first condition, We know that two successive discounts of $a$% and $b$% are equivalent to $(a+b-\frac{a×b}{100})\%$ So, two successive discounts of 10% and 15% are equivalent to, $(10+15-\frac{10×15}{100})=23.5$% For the second condition, So, discount = $\frac{7-5}{7}×100=28.57$% So, the scheme which has the maximum

Question : In a $\triangle ABC, \angle B=\frac{\pi}{3}, \angle C=\frac{\pi}{4}$ and D divides BC internally in the ratio 1 : 3, then $\frac{\sin \angle BAD}{\sin \angle CAD}$ is equal to:
Option 1: $\frac{1}{\sqrt{2}}$
Option 2:
$\frac{1}{\sqrt{3}}$
Option 3:
$\frac{1}{\sqrt{6}}$
Option 4: $\sqrt{6}$
Correct Answer:
Solution : Given: $\triangle ABC, \angle B=\frac{\pi}{3}=\frac{180°}{3}=60°,$ and $\angle C=\frac{\pi}{4}=\frac{180°}{4}=45°$ So, $\angle A= 180°-(60°+45°)=75°$ In triangles $ABD$ and $ACD$, we have: $\frac{AB}{\sin B}=\frac{BD}{\sin \angle BAD}$ and $\frac{AD}{\sin C}=\frac{CD}{\sin \angle CAD}$ ⇒ $\frac{\sin C}{\sin B}=\frac{\sin \angle CAD}{\sin \angle BAD}×\frac{BD}{CD}$ ⇒ $\frac{\sin 60°}{\sin 45°}=\frac{\sin \angle CAD}{\sin \angle BAD}×\frac{1}{3}$ ⇒

Question : At what time will a 100 metres long train running at a speed of 50 km/h cross a pillar?
Option 1: 7 seconds
Option 2: 72 seconds
Option 3: 7.2 seconds
Option 4: 70 seconds
Correct Answer: 7.2 seconds
Solution : Given: The distance of the train is 100 m. The speed of the train is 50 km/h. We know that, $\text{Time}=\frac{\text{Distance}}{\text{Speed}}$ To convert km/h into m/s, multiply with $\frac{5}{18}$, we get, $50\times \frac{5}{18}=\frac{125}{9}$ m/s So, the train takes time to cross the pillar =
